Abstract:
Disclosed is a method for making a poly-lactic acid/silica composite. At first, silica particles are aminated, thus providing aminated silica particles. Secondly, the aminated silica particles are mixed with poly-lactic acid. Then, the mixture is blended and extruded by two micro-screws, thus providing a poly-lactic acid/silica composite. Thus, the mechanical properties of the poly-lactic acid are improved without affecting the biodegradability of the poly-lactic acid.
