Preparation and Properties of Polylactide/Nano-Silica Composites
Polylactide/nano-silica composites were synthesized with lactide and modified nano-silica by tin octoate catalyst. The structures and properties of the composites were characterized by FT-IR, TG and SEM. The results of FT-IR and SEM showed that nano-silica and polylactide are connected with covalent bonds, and inorganic phrases is dispersed in polylactide homogeneously. The results of TG indicated that thermal decomposition temperature is increased with the increasing of silica content. The tensile strength of composites was enhanced because of adding nano-inorganic particles into polylactide.
