Ceramic Nanocomposites

This chapter reviews the various properties enhancement of polymer/ceramic nanocomposites. Ceramics nanofillers have attracted both academic and industrial interest as they can produce a significant improvement in the properties of polymers even at lower filler loadings. Recently, numerous kinds of polymeric matrices reinforced with ceramic nanoparticles have been reported. The surface-modification of ceramic nanoparticles was reported to provide extra-improvements in the thermal and mechanical properties of these materials. In addition, the type of the used ceramic nanofillers agent determines the final properties of the nanocomposites. Herein, the various effects of adding ceramic nanoparticles on the thermal, electrical, optical, and mechanical properties of polymer/ceramic nanocomposites as well as the reinforcing mechanism are discussed in general along with detailed examples drawn from the scientific literature.

A composite of laser-activate particles and the super engineering plastic of polyphenylene sulfide was fabricated via melt-mixing. The laser-activate particle surfaces were modified using hydroperoxide and three different silane coupling agents. The laser-activate particles dramatically deteriorate the mechanical properties of polyphenylene sulfide because of its low compatibility with the polymer. However, surface modification, especially via amino silane treatment, effectively prevented the degradation of thermal and mechanical properties upon adding laser-activate particle, while modification with phenyl silane had the reverse effect. In order to confirm the different effects, solubility parameters obtained by theoretical calculation via the group contribution method were compared. Thermally and mechanically enhanced laser-activate particle/polyphenylene sulfide composites were fabricated for laser direct structuring and electroless plating applications.
