Micro/Nano‐Pores and Anti‐Fingerprint Coating by Vacancy‐Capture and Interface Intelligent Control

In this work, a simple anti-fingerprint strategy (reduced ≈40–60%) to rearrange fingerprint droplets by patterned micro/nano-pore/spoons texture, air cushion and low surface energy is reported. Superior previous precise complex preparation methods, the micro/nano-texture are fabricated through conventional process of spray dip. The pore spoon can be freely switched changing process. number (N) size (r) pores spoons controlled intelligently solvent volatilization interfacial tension ( γ FP/PU − H 2 O ${{\bm{\gamma }}_{{\rm{FP/PU}}{\bm{ - }}{{\rm{H}}_2}{\rm{O}}}}$ γFP/PU Solvent), key for pore/spoon's forming expanding. A physical model interface intelligent controlling micro/nano-pore/spoon texture induced “Vacancy-Capture” proposed. description being reported, first time, knowledge, expecting make it possible prepare engineering materials with newly potential industrial applications on optical device large-scale in future.
