ABSTRACT
This research studied the effect of three types of starch on the properties of thermoplastic starch (TPS)–Poly (vinyl alcohol) (PVA)–cellulose nanocomposite films. Three different types of starch with amylose and amylopectin contents used were corn starch, cassava starch, and sago starch. Meanwhile, the nanocellulose was isolated from oil palm empty fruit bunches (OPEFBs) by mechanical treatment using ultrafine grinder. The nanocomposite films were made by evaporation casting method. It was found that the difference of amylose content in the native starch affected the properties of nanocomposite films. Meanwhile, the nanocellulose added into matrix TPS–PVA could increase tensile strength of TPS–PVA nanocomposite films.
摘要
研究了三种淀粉对热塑性淀粉（TPS）-PVA-纤维素纳米复合膜性能的影响.淀粉酶和淀粉果胶含量不同的三种淀粉是玉米淀粉、木薯淀粉和西米淀粉.同时，采用超细粉碎机对油棕空果串（OPEFB）进行机械处理，得到纳米纤维素.采用蒸镀法制备了纳米复合薄膜.结果表明，天然淀粉中淀粉酶含量的不同影响纳米复合膜的性能，同时，在基体TPS-PVA中加入纳米纤维素可以提高TPS-PVA纳米复合膜的拉伸强度.
