Awareness of the environmental impact of using polymeric materials obtained from petroleum is causing increased interest in sustainable materials manufacturing. Here, we present the elaboration of fully biobased materials using an aromatic epoxy resin matrix coming from wood biomass and two natural by-products, namely, keratin from chicken feathers and lignin. In situ FTIR kinetic studies show that the two natural fillers increase the conversion of the epoxide during cross-linking. This result, together with DSC studies, proves the chemical interactions between the keratin or lignin and the epoxide network. Up to 30% of these natural components could be reacted and incorporated into the epoxide with good compatibility. The thermomechanical properties of the elaborated materials are comparable to those of commercial ones.

通过将生物基环氧树脂与角蛋白和木质素交联来设计可持续材料

意识到使用从石油中获得的聚合材料对环境的影响，引起了人们对可持续材料制造的关注。在这里，我们介绍了使用源自木材生物质的芳族环氧树脂基质和两种天然副产品，即来自鸡毛和木质素的角蛋白，对完全生物基材料进行的详细说明。原位FTIR动力学研究表明，两种天然填料在交联过程中提高了环氧化物的转化率。该结果与DSC研究一起证明了角蛋白或木质素与环氧化物网络之间的化学相互作用。这些天然成分中最多有30％可以反应并以良好的相容性掺入环氧化物中。精制材料的热机械性能可与市售材料相比。
