从农业来源获得的蛋白质代表了制备可热加工聚合物的独特原料。在这项研究中，热处理羽毛角蛋白膜堆肥与三个月大的堆肥接种物在自热实验室堆肥30天，温度和二氧化碳的发展监测。羽毛角蛋白聚合物（FKP）中约24%的可用碳在这段时间内代谢，这对于某些应用来说可能不够高。在10天内观察到羽毛角蛋白聚合物的降解，同时使用FT-IR测量分子量降低。在DSC分析中观察到结晶度的变化，并且也可以由此推断出一些降解过程。由爱思唯尔有限公司发布
Proteins obtained from agricultural sources represent a unique feedstock from which to prepare thermally processable polymers. In this study, thermally processed feather keratin films were composted with three-month-old compost inoculum in self-heating laboratory composters for 30 days and temperature and carbon dioxide development monitored. About 24% of the available carbon in the feather keratin polymer (FKP) was metabolized in this time and this may not be high enough for some applications. Degradation of the feather keratin polymers was observed within 10 days with concurrent molecular weight reduction measured using FT-IR. Visual inspection of the polymers also showed destruction of the films. A change in crystallinity was observed in DSC analysis and some degradation processes could be inferred from this as well.
