Properties Of Composites

In this paper several properties of new materials based on polymer blends were studied. The properties of composites made of the blends of chitosan and collagen with addition of poly (methyl methacrylate) and hydroxyapatite were investigated. Mechanical properties, thermal analysis, FTIR spectra and SEM images were obtained for different blends of chitosan/collagen in weight ratios 75/25, 50/50, 25/75. Poly (methyl methacrylate) was used in ratios 15, 50 and 85 wt% based on chitosan. The influence of the addition of hydroxyapatite to the polymer blends on their properties was tested. The results showed that the amount of components can influence on the mechanical properties observed for obtained materials.

ABSTRACTSolid sol of silver in poly(methyl methacrylate), Ag/PMMA, was prepared by bulk polymerization of methyl methacrylate solution of silver (I) triflluoroacetate (AgTfa) and followed by postheating. The formation of the metallic Ag nanocluster was characterized by visible spectroscopy, and effects of the concentrations of AIBN and AgTfa and the heat-treatment duration on the formation of Ag cluster were investigated. Furthermore, based on the kinetic study of MMA in the presence of AgTfa, possible mechanism for the reduction and agglomeration of silver is proposed.
