| Abstract: | It prepared the thermoplastic starch plastics (TPS) by means of plasticizers and heat shearing method,and determined the water content of TPS with different formulas under certain conditions of relative humidity.It studied the effects of the kinds and content of plasticizers (glycerol and formamide),the contents of amylose and polylactic acid (PLA) on the water absorption of TPS.It proved Peleg model is effective and reliable in describing the process of water absorption of TPS through the fitting analysis of the water content-time curve and the Peleg model curve. |
