제목 Silica-Perfluorinated Polymer Composite Nanoparticles for Superhydrophobic Surfaces
초록 Herein, we report a simple technique to fabricate robust and efficient superhydrophobic surfaces by spray coating silica-core/perfluorinated polymer-shell composite nanoparticles (silica@PFA NPs) onto the adhesive-coated surface. The novel silica@PFA NPs were prepared by covalently attaching perfluoroalkyl acrylate on the surface of the silica nanoparticles. The fluorinated shell thickness in the silica@PFA NPs could be easily controlled by varying the degree of polymerization and the NPs underwent spontaneous assembly to form complex micro/nano dual scale roughness after spray coating. In addition, we introduced an epoxy adhesive layer in between the NPs and the substrate, which led to a high mechanical robustness of the surface from external damages. Thus, outstanding superhydrophobic performance and mechanical stability could be achieved simultaneously and in a simple manner.
