| Abstract | A simple and conventional coating-curing process to fabricate superhydrophobic coating surface wboth themicro-nano-scale binary structure (MNBS) roughness, and the lowest surface energy hydropbic groups (−CF3) on engineeringmaterials of stainless steel or othermetalswas developed by controcuring conditions. Results showthat higher temperature and longer cooling time resulted in longer ctallizing process, and the forming PTFE aggregates could slowly produce the crystallization and crethe willow-leaf-like or wheat-haulm-leaf-like polymer micro/nano-fiber on the atop surface. The cing temperature dramatically influences themicro/nano-fiber texture of the PTFE/PPS superhydrophocoating surface, leading to the excellent superhydrophobicity at higher temperature. An increase ofcuring temperature is beneficial to fluorine gradient-distribution, PPS thermal-oxidative cross-linkand oxidative reaction, resulting in the enhancement of adhesive strength and mechanical properof the PTFE/PPS superhydrophobic coatings. A bionic superhydrophobic surface with porous gel-network and PTFE micro/nano-fiber textures could be created by natural cooling in air, whereas Pnano-sphere/-papillates textures could be fabricated by hardening in H2O. |
