Stainless-steel-net-supported superhydrophobic COF coating for oil/water separation

This work reports the preparation and post-synthetic modification of COF named BTADHBD with perfluorooctyltriethoxysilane (POTS) to obtain a superhydrophobic COF coating. Through post-synthetic modification, the water contact angle (CA) of BTADHBD is increased from 83.7° to 153.2° without change of crystals morphology and structure. BTADHBD COF coating was prepared on the stainless steel net (SSN) through repeated growth, followed by...
