摘要

这项研究的重点是含有氧化锌和二氧化钛的生物塑料和复合生物塑料。与使用二氧化钛制成的薄膜相比，氧化锌制成的薄膜更加透明。研究了这些添加剂对薄膜的物理和机械性能、生物降解性、表面形态和热性能的影响。傅立叶变换红外光谱确认了生物塑料和复合材料中的官能团 O-H、C-H、C=O 和 C-O。ZnO 和 TiO2 的添加可提高热稳定性。复合材料的拉伸强度高于对照生物塑料薄膜。生物塑料薄膜的生物降解率为 100%，而含有 ZnO 和 TiO2 的生物塑料薄膜的生物降解率分别为 14.71% 和 14.59%。

Characterization of composite bioplastic from Cassava starch with titanium dioxide and zinc oxide

This study focused on bioplastics and composite bioplastics with incorporated ZnO and TiO2. The ZnO gave a film more transparent than that made with TiO2. The effects of these additives on physical and mechanical properties, biodegradability, surface morphology, and thermal properties of the films were investigated. The functional groups O-H, C-H, C=O, and C-O in the bioplastic and the composites were confirmed by FT-IR. The addition of ZnO and TiO2 could increase thermal stability. The composites exhibited higher tensile strength than the control bioplastic film. The bioplastic film was 100% biodegradable compared to 14.71% and 14.59% for ZnO and TiO2 containing bioplastic films, respectively.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
