Chemistry and technology of nanoparticles : preparation, processing and application

Abstract

A fabrication and a processing process of nanoparticles by chemical synthesis routes have been developed for ceramic and nanocomposite materials. The investigation shows that microemulsion and controlled growth processes followed by solvo-thermal treatment can be used for the preparation of agglomerate-free powders to be either incorporated into polymer matrices for nanocomposites or to be processed to ceramics. For obtaining green densities up to 60% by volume, appropriate surface modification techniques for controlling the particle-to-particle interaction have been developed. As alternative route also leading to nanocomposites, the so-called in situ process has been established. For this route, alkoxide and organic nanomer containing systems are hydrolysed, processed to films or bulk components with optical quality.
