Progresses of the Effects of Inorganic Substance on Mechanical Properties of Starch Plastics
Starch has been a major source for preparing biodegradable plastics because of its inherent biodegradability,ready availability and relatively low cost.The research and application of starch plastics have been developed rapidly in recent years.The research interest is focused on improving the performance (mechanical and water resistance etc).Nowadays,inorganic or mineral fillers are widely used in composite materials to improve its performance.In this paper,the progress of the effects of inorganic substances on mechanical properties of starch plastics is reviewed in recent years.According to their different categories,we mainly reviewed the effect of inorganic substances on the mechanical properties of starch plastics,including oxide,hydroxide carbonate,silicate and phosphate salt etc.At last,the latest research progress,problems,and the trend in the future are also proposed.
