摘要：

Poly(ethylene-co-vinyl acetate) (EVA)/Calcium phosphate nanocomposites were prepared by melt mixing in a Brabender plasticoder. Nanoparticles of calcium phosphate were synthesized by the polymer-mediated synthesis and characterized by X-ray diffractometry and transmission electron microscopy. Mechanical properties such as tensile strength, tensile modulus, tear strength, etc., were measured with respect to the filler loading. Thermal stability of the composites under nitrogen atmosphere was also measured. The composites showed better thermal stability due to the nanoreinforcement. Oxygen gas permeability of the composites showed considerable decrease due to tortuous path created by the nanofillers. POLYM. COMPOS., 31:1011-1019, 2010. (C) 2009 Society of Plastics Engineers
