摘要
采用熔融挤出法制备了热塑性橡实淀粉(TPAS)/聚己内酯(PCL)二元复合材料。通过复合材料的拉伸测试、接触角、吸水性、吸湿性、FTIR、SEM、MIR、DMA和土埋实验,研究了PCL含量对复合材料力学性能、疏水性能、热性能和降解性能的影响,结果表明复合材料不仅具有较强的吸水性,还具有优异的力学性能、熔融流动性能和降解性能。
The binary composites of thermoplastic acorn starch(TPAS)/polycaprolactone(PCL) are produced by hot-melt extrusion method. The effects of PCL content on mechanical, hydrophobic, thermal and degradable properties of composites are studied by tensile test, contact angle, water absorption, moisture absorption, FTIR, SEM, MIR, DMA and soil burial degradation analysis. Researchs show that composites have more hygroscopicity, but the mechanical, melt flow and degradation properties of composites are favorable.
