Plasma?Assisted Deposition of TiO ₂ 3D Nanomembranes: Selective Wetting, Superomniphobicity, and Self?Cleaning

Fabrication of tunable wetting surfaces is sought for the last years given its importance on energy, biomaterials and antimicrobials, water purification, microfluidics, smart surfaces. Liquid management mainly depends control at micro- nanoscale both roughness chemical composition. Herein, combination a soft-template method plasma-enhanced vapor deposition presented synthesis TiO2 nanofibers porous substrates such as cellulose stainless-steel membranes. The protocol, carried out under mild conditions, produces 3D nanomembranes with superhydrophobicity oleophilicity that are tested microliter water/oil filters. Photoactivation by UV illumination provides straightforward approach tunability converts surface into amphiphilic. A final modification embedding them in an elastomeric polymeric shell fluorine-based grafting opens path toward formation superomniphobic self-cleaning long-lasting lifetimes. Thus, reliable procedure demonstrated fabrication nanofibers, which allows supports innovative route development design wetting. This protocol extendable to alternative metal oxides, metals, core@shell nanoarchitectures potential multifunctionalities.
