Achieving sandwich-like laminated composite materials for robust superhydrophobicity, rapid photochromism and photo-mask writable media

Abstract

Photochromic materials with anti-water properties have impressed practical values, but their applications are severely hindered by poor stability and slow colour-switching rate. Inspired by the superhydrophobicity of lotus leaf and...

Color morphing surfaces with effective chemical shielding

“…One way of overcoming this challenge is by imparting superrepellency (i.e., extreme repellency to liquids) [12][13][14][15][16][17][18][19][20][21] to photochromic materials, thereby providing effective chemical shielding. While there are prior reports on imparting superhydrophobicity (i.e., extreme repellency to high surface tension liquids like water) [22][23][24][25] , to the best of our knowledge, there are no reports on imparting superomniphobicity (i.e., extreme repellency to both high and low surface tension liquids) to photochromic materials. Here, we emphasize that superomniphobic surfaces impart improved chemical resistance compared to superhydrophobic surfaces 16 .…”
