INORGANIC NANOPARTICLES IN POLYMER MATRIX COMPOSITES

Abstract

Polymer – inorganic nanoparticles composites present an interesting approach, because by combining the attractive functionality of both components result new materials with synergistically improved properties. The objective of this paper was to examine the structure and properties of a new type of composite materials based on thermoplastic polymers and inorganic nanoparticles. It is very difficult for inorganic nanoparticles to disperse in the polymer matrix through conventional mixing, because the nanoparticles have high surface energy and have tendency to agglomerate during mixing. So, surface of inorganic nanoparticles was modified with a capping agent, who it was used to improve the interface between the organic and inorganic phases. Chemical structure, particle size distribution and surface morphology of the obtained composites were characterized using Fourier infrared spectra
