Silica-coated polymeric particles were synthesized based on the cationic colloidal particles which were prepared by precipitation polymerization of Divinylbenzene(DVB) in the presence of a cationic monomer, dimethylaminopropyl methacrylamide(DMAPMA) using 2,2'-Azobisisobutyronitrile(AIBN) as an initiator. Negatively charged silica precursors were rapidly hydrolyzed onto the cationic surfaces of colloidal particles. The resulted poly(DVB-co-DMAPMA)/silica core/shell particles were characterized by scanning electron microscopy (SEM). Then, the fabrication of a superhydrophobic particle surface was achieved by coupling reaction of the poly(DVB-co-DMAPMA)/silica core/shell particle surface with nonafluorohexyltriethoxysilane. The water static contact angle on the surface of epoxy layer with rough microstructures was investigated on a contact angle system. |
