摘要
以甘油作为增塑剂,采用熔融共混法制备了小麦蛋白/聚乳酸(WG/PLA)共混物,研究了WG/PLA共混物的流变性能、黏弹性能和热机械性能。研究结果表明:随着甘油和PLA含量的增加,WG/PLA共混物的流动性逐渐增强,储能模量、损耗模量和热变形温度逐渐降低。
Blend of wheat gluten (WG) and poly (lactic acid) (PLA) was plasticized with glycerol by using an internal mixer. The rheological behavior, viscoelasticity and thermal mechanical property of the WG/PLA blend were investigated. Results show that with the amounts of glycerol and PLA increasing, the fluidity of the blend increases, whereas the storage modulus, loss modulus and thermal deformation temperature of the blend decrease.
