PLCL/CNT 电纺层合材料借 Bouligand 结构兼顾力学与传感
Architectural Tuning of Bouligand Electrospun Laminates Enables Coupled Mechanical Robustness and Electromechanical Sensing
AI 导读
研究将蓝蟹外骨骼的螺旋 Bouligand 结构移植到可生物降解的电纺 PLCL 层合材料中，并嵌入 CNT 传感层。在成分相同的前提下改变层间旋转角，20° 旋转使杨氏模量较随机堆叠层合材料提高三倍以上、拉伸强度提高近 40%；厚度约 100 µm 的层合材料可承受超过自身厚度 55 至 73 倍的面外变形，CNT 网络可实时检测结构损伤。
推荐理由
原文用层间旋转角这一单一变量，把 Bouligand 结构与模量、传感输出的对应关系拆开，可迁移到其他电纺层合体系。
创新点
以层间旋转角为唯一变量，把生物螺旋结构与电纺层合材料的力学增强和 CNT 传感输出定量对应起来，同一材料同时承担承载与损伤自检测功能。
