Abstract

Plastics play a significant part in human life and the world we live in. The use of plastics results in detrimental effects on the natural world, which compels us to look for viable replacements. As a result of their enhanced capacity to biodegrade, bioplastics are becoming increasingly important materials. In recent years, there has been a rapid ascent in the utilization of biopolymers in various applications. The objective of this research is to investigate the impact that silica obtained from rice hull ash (RHA) and microcrystalline cellulose (MCC) obtained from groundnut husk have on the properties of bioplastic obtained from wheat gluten and fish scales. The usage of fish scales has been shown to have a positive effect on weight reduction and debasement rates. Microcrystalline cellulose (MCC) is utilized in a wide range of concentrations, and the influence of MCC on bioplastic is researched. The biodegradability tests of bioplastic revealed that the plastic lost 35% of its weight in just 14 days. The experiments that were done to evaluate the chemical stability and tensile strength of the bioplastic indicated that the MCC content has a significant effect in improving the characteristics of the material.

摘要

塑料在人类生活以及我们生活的世界中扮演着重要角色。塑料的使用对自然世界产生了有害影响,这迫使我们去寻找可行的替代品。由于生物塑料具有更强的生物降解能力,它们正成为越来越重要的材料。近年来,生物聚合物在各种应用中的使用迅速增加。本研究的目的是探究从稻壳灰中获得的二氧化硅以及从花生壳中获得的微晶纤维素对由小麦面筋和鱼鳞制成的生物塑料性能的影响。鱼鳞的使用已被证明对减重和降解率有积极影响。微晶纤维素(MCC)以多种浓度使用,并研究了MCC对生物塑料的影响。生物塑料的生物降解性测试表明,该塑料在短短14天内重量损失了35%。为评估生物塑料的化学稳定性和拉伸强度而进行的实验表明,MCC含量对改善材料特性有显著影响。
