Abstract

In this paper, the mechanical and morphological properties of biodegradable SAN/EOC/Nanoclay/Proteins nanocomposite were investigated. The composites were first prepared by a laboratory-scale twin screw extruder. Morphology of the blend was determined by SEM images. Mechanical properties in terms of tensile tests were carried out by Testometric TS2000, stress at break, strain at break, and Young’s modulus was determined. Based on mechanical results, although the young’s modulus increases with increasing protein content but the strain at break of the composite decreases acutely because of the presence of protein. The blend indicated an improvement in mechanical and thermal properties. Today, according to the vast application of plastic in different fields, environmental issues were affected by these kinds of non-degradable materials, so that biodegradability of the plastics is just the remaining route to solve. In this research, biodegradable blends were prepared using whey protein as a biodegradable natural polymer. The results of the biological procedure-test after 3 months indicated sufficient weight loss and biodegradation of these blends.
SAN/EOC/纳米粘土/蛋白质纳米复合材料的制备、物理力学性能及生物可降解性研究
本文研究了可生物降解的SAN/EOC/纳米粘土/蛋白质纳米复合材料的力学性能和形态性能。该复合材料首先通过实验室规模的双螺杆挤出机制备。通过SEM图像确定共混物的形态。通过Testometric TS2000进行拉伸试验方面的机械性能,测定断裂应力、断裂应变和杨氏模量。根据力学结果,尽管杨氏模量随着蛋白质含量的增加而增加,但由于蛋白质的存在,复合材料的断裂应变急剧降低。该混合物表明其机械性能和热性能有所改善。如今,随着塑料在不同领域的广泛应用,这些不可降解材料影响了环境问题,因此塑料的生物降解性只是剩下的解决途径。在本研究中,以乳清蛋白作为可生物降解的天然聚合物制备了可生物降解混合物。3个月后的生物程序测试结果表明,这些共混物具有足够的重量损失和生物降解性。

期刊介绍: Polymers from Renewable Resources, launched in 2010, publishes leading peer reviewed research that is focused on the development of renewable polymers and their application in the production of industrial, consumer, and medical products. The progressive decline of fossil resources, together with the ongoing increases in oil prices, has initiated an increase in the search for alternatives based on renewable resources for the production of energy. The prevalence of petroleum and carbon based chemistry for the production of organic chemical goods has generated a variety of initiatives aimed at replacing fossil sources with renewable counterparts. In particular, major efforts are being conducted in polymer science and technology to prepare macromolecular materials based on renewable resources. Also gaining momentum is the utilisation of vegetable biomass either by the separation of its components and their development or after suitable chemical modification. This journal is a valuable addition to academic, research and industrial libraries, research institutions dealing with the use of natural resources and materials science and industrial laboratories concerned with polymer science.
