TiO2/EP superhydrophobic composite coating with excellent mechanical and chemical stability

Superhydrophobic coatings have great influence in various applications because of their excellent hydrophobic properties. The focus of current research is to develop superhydrophobic coatings with excellent mechanical and chemical stability. In this work, silane coupling agent KH560 was used to modify titanium dioxide nanoparticles (TiO2) and blend them with epoxy resin E51 (EP). The mixed composite material was sprayed on the substrate for curing treatment. Form TiO2/EP superhydrophobic coatings with excellent mechanical and chemical stability. By adjusting the mass ratio of TiO2 to EP, it is found that the 1:3 TiO2/EP coating has excellent mechanical and chemical stability while having a contact Angle of 159.5° ± 1.5°. The layered bone structure brought by the modification of TiO2 by KH560 gives the coating excellent corrosion resistance. A series of tests have proved that the coating has a wider application prospect in super hydrophobic properties and harsh outdoor conditions.
