Abstract

Simple drop-casting of a new gelator, incorporating a diacetylene core and fluorous ponytails, yields porous xerogels as surface coatings. The mechanical stability of such coatings is quantified with a self-devised...

通过将自组装超分子干凝胶转化为共价聚合物干凝胶实现全疏水、可浇铸表面涂层的光稳定†

一种新型凝胶剂的简单滴注，结合了二乙炔芯和含氟马尾辫，可以产生多孔干凝胶作为表面涂层。通过自行设计的划痕天平对此类涂层的机械稳定性进行量化，引入了一种简单通用的量化方法来比较微米级涂层的稳定性。涂层中孔隙的直径可以通过呼吸图形效应来控制。涂层显示出全疏性，静态接触角高达139°（水）和96°（正癸烷）。涂层通过紫外线辐射进行拓扑化学聚合，将机械稳定性提高了四倍。同时，由于表面粗糙度的轻微增加，水和正癸烷的接触角分别增加了约9°和4°。

期刊介绍： Materials Chemistry Frontiers focuses on the synthesis and chemistry of exciting new materials, and the development of improved fabrication techniques. Characterisation and fundamental studies that are of broad appeal are also welcome. This is the ideal home for studies of a significant nature that further the development of organic, inorganic, composite and nano-materials.
