PREFACE

On behalf of the FP7 Project NANOTECH FTM and the Organizing committee we would like to welcome you to the first International Workshop on Processing of Nanostructured Ceramics, Polymers, and Composites at the Faculty of Technology and Metallurgy, University of Belgrade.
The Workshop aims to present current advances in processing of nanomaterials. It will be organized as oral sessions with invited speakers from the international as well as local academic, scientific, and industrial communities, as poster session for presentations of young researchers, and a round table “Nanotechnology today – where is it going?”, which will initiate discussions on fundamental issues and application potentials of contemporary nanotechnology.
It is our hope that NANOTECH FTM project results will contribute to the increasing level of research in this area and in the way bring scientific and industrial institutions in Serbia closer to activities and objectives of European Research Area. This event will raise public and professional attention of the contemporary research in nanotechnology and advanced functional materials.
We express our gratitude to the invited Speakers and Networking Partner members for their contribution to the scientific level of the Workshop and participation in the round table meeting. The event is supported with the enthusiasm of the Faculty staff and colleagues from other institutions in organizing details, promotion and other assistance, which is sincerely acknowledged.

Development of Multifunctional Advanced Composites with Polymer Nanocomposite Matrices for Damage Sensing Applications
M. Monti, M. Natali, R. Petrucci, L. Torre, J. M. Kenny
University of Perugia, Civil and Environmental Engineering Department, Terni, Italy
In recent years, nanotechnology has given the importance chance of tailoring properties of a material, depending on its final application. In fact, the ability on handling materials at nanoscale level can lead to advancements which were unthinkable just two decades ago. Among the nano-scaled particles that are commonly included in plastics for enhancing their properties, carbon nanotubes and nanofibers have a particular role, because of their electrically active behaviour, which is very interesting when it is necessary to modify the electrical conductivity of a plastic material: for this reason, they can be considered as intrinsically multifunctional nanoparticles.

Thermosetting matrices are commonly employed as matrices for fiber reinforced polymers. Polymer-based fiber reinforced composite materials are widely used in applications in which they have a structural role, in many different sectors such as aerospace, automotive and machinery in general, as well as in civil engineering. In these cases, it is very important to have the chance of detecting the presence of strain accumulation and the presence of any damages, which can worsen the mechanical resistance of the composite itself.

Since design and functionality requirements of engineering structures such as spacecraft, aircraft, vessels, buildings, dams, bridges and vehicles is becoming more multifaceted, structural health monitoring and damage evaluation is becoming more critical. Researchers have demonstrated that no single technique used on its own provides reliable results on this topic. Among traditional non-destructive inspection methods to evaluate structural integrity, real-time structural health monitoring systems represent a key technology to ensure the reliability of a fiber reinforced composite structure.

The use of techniques that exploit electrical properties of the composite to monitor damages has been recognized as a non-invasive way in carbon fiber reinforced plastic, since the good electrical conductivity of carbon fibers themselves. In fact, in this case, fracture of fiber results in a strong increase of electrical resistance. Nonetheless, this approach does not consider the fractures involving the matrix and the fiber-matrix interface, so it can give just a partial view of what could happen inside the composite during a mechanical solicitation. Moreover, it can not be employed with non-conducting fibers, e.g. glass or aramid. For this reason, some researchers has begun to investigate the possibility of the employment of electrically modified polymeric matrices.

In this study, both unsaturated polyester and an epoxy resins were doped with carbon-based electrically conductive nanoparticles, such as carbon nanofibers and nanotubes, in order to obtain a matrix with enhanced electrical conductivity for the production of a glass fiber reinforced composite. In the case of the polyester resin, the calendering technique was employed for the dispersion of the nanoparticles in the
matrix. The benefits of the calendering process are strictly related to the fact that it is already an industrial process, although in different applications, and so it can be considered an easily up-scalable technique. A common mechanical stirring was employed for the mixture epoxy-CNTs.

Glass fiber reinforced composites produced by liquid molding processes, were studied by mechanical and electrical tests. In particular, for the polyester-based composite a flexural load was exerted at the same time as electrical resistance was measured, in order to verify whether any change in resistance is related to the mechanical stress. On the other hand, the possibility on monitoring the presence of a damage for the epoxy-CNT-matrix composite was focused on impact damages.

This study has demonstrated how just a very low content of high aspect ratio carbon nanoparticles leads to a completely different electrical behaviour of the matrix and to the final glass fiber composite. Therefore, carbon nanotubes and nanofibers, when employed in glass fiber composites, can be considered a very interesting tool for strain and damage sensing.

New Developments in the Field of Nanostructured 3D Scaffolds for Bone Tissue Engineering
A. R. Boccaccini
Institute of Biomaterials, University of Erlangen-Nuremberg, Erlangen, Germany
Tissue engineering aims to restore function to diseased or damaged tissue using combinations of functional cells and biodegradable highly porous scaffolds made from engineered biomaterials. The main function of a tissue engineering scaffold is to act as substrate for cell attachment and proliferation and subsequent tissue growth. In this presentation current research in the area of advanced scaffolds for bone tissue engineering which are based on composite bioactive nanostructured materials will be discussed. Particular systems of interest are a new generation scaffolds based on nanostructured porous composite materials fabricated from combinations of biodegradable polymers and bioactive inorganic fillers and coatings, e.g. bioactive glass, TiO₂ nanoparticles or carbon nanotubes. For applications in bone tissue engineering Bioglass® based glass-ceramic scaffolds are favoured. The scaffold microstructure comprises a highly porous network (> 90% porosity) and densified struts exhibiting also the presence of nanoscale crystals (e.g. Na₂Ca₂Si₃O₉), which lead to improved compressive strength of the foam structure. The coating of the foam struts with a thin biodegradable polymer layer containing functionalised carbon nanotubes, biodegradable polymer nanofibres (by electrospinning) or nanoscale bioactive glass particles increases the mechanical competence of scaffolds and induces the formation of a nanostructured hydroxyapatite layer upon immersion in simulated body fluid. This layer promotes the adhesion of newly formed bone tissue on the scaffold surface. Ideally, these scaffolds should not only be osteoconductive providing a passive structural support for bone cells, but they also should favourably affect bone formation by stimulating osteoblastic cell proliferation and differentiation. Since many trace elements such as Sr, Cu, Zn, V or Co presented in the human body are known for their anabolic effects in bone metabolism, new approaches for enhancing bioactivity of scaffold materials are being investigated by introducing therapeutic ions into the scaffold material. The effect of these ions on the osteogenic and angiogenic properties of the constructs will be presented and discussed.

Recent developments of multifunctional scaffolds containing carbon nanotubes will be also presented, including the description of the electrophoretic deposition (EPD) technique developed to manipulate and control the deposition of electrically charged nanoscaled particles and other nanostructures on scaffold surfaces. It will be shown that nanostructuring the 3D porous scaffolds has also the benefit of mimicking the structural scale of proteins in the body and as such it promotes the attachment and proliferation of cells, leading to enhanced biological performance of the scaffolds in-vitro and in-vivo.
