仿贻贝足丝同源梯度界面相纤维膜实现热冲击下稳定的相变缓冲与辐射冷却
Bioinspired Homologous Gradient Interphase Sustains Phase‐Change Buffering and Radiative Cooling Under Thermal Shocks
AI 导读
研究团队仿贻贝足丝的分级应力传递，构建了核-梯度界面相-壳纤维膜（Ho-GIFM），在同轴静电纺丝中让同源聚乙二醇基聚氨酯在界面互扩散缠结，并用原位 UV 交联稳定界面相。
推荐理由
同源梯度界面相把相变应变分散到界面，读者可据此理解纤维相变膜在热冲击下保持辐射制冷性能的结构思路。
创新点
用同源聚乙二醇基聚氨酯在界面互扩散并原位 UV 交联形成梯度界面相，把相变产生的应变分散到界面并抑制长程链重排，从而在反复热冲击下同时保住相变功能与多孔纤维网络。
