研究团队用一步引发式化学气相沉积在多种基底上制备聚合物纳米褶皱涂层
Substrate-Independent Polymeric Nanowrinkled Coatings Synthesized via One-Step Initiated Chemical Vapor Deposition
AI 导读
研究团队通过顺序 iCVD 沉积 PV3D3 与 PPFDA，在不预拉伸、不热收缩、不使用弹性体基底的情况下制得聚合物纳米褶皱涂层。该涂层水接触角超过 150°，具有自清洁性能，可使水滴冻结时间较裸石英延长 7 倍并延缓结霜，同时显著减少细菌附着。涂层在水性、酸性和碱性环境中长时间暴露后仍保持形貌、化学组成与疏水性。
推荐理由
该工作用全气相 iCVD 顺序沉积在刚性基底上直接生成纳米褶皱，读者可据此判断无需预拉伸的褶皱涂层路线。
创新点
与依赖基底形变或预拉伸的褶皱制备策略不同，该工作用全气相顺序 iCVD 在刚性或复杂基底上直接生成纳米褶皱，并同时获得超疏水、抗结霜与抗细菌附着性能。
