摘要： This study proposed an eco-friendly method to prepare biocomposite pots using straw fiber and hydrolyzed keratin (HK)-modified urea-formaldehyde (UF) resin, and investigated their interphase and degradation behavior in depth by nanoindentation (NI). The results showed that HK was successfully grafted onto UF resin molecular structure with epoxy group as intermediate, which increased the molecular weight and rheological properties of the resin. Moreover, the mechanical properties and degradability of the biocomposite pots were also improved. When 6 wt% HK was added (RS-K6EUF), the degradation rate of the biocomposite pot after 6 months of soil burial was increased by 44.31% compared to the blank pot (RS-UF). Furthermore, the study on the degradation behavior of the interphase indicated that the degradation rate of RS-UF mainly depended on the fiber, while RSK6EUF was more affected by fiber-resin interphase. This research endeavor significantly advances the fundamental understanding of the degradation mechanisms of biocomposites.
