Poly(benzylsilsesquioxane) (BnSiO3/2) particles show glass transition behavior, and the particles become a supercooled liquid when they are heated at temperatures above the glass transition temperature. Contact angles of BnSiO3/2 molten liquid on the hydrophobic surface with fluoroalkylsilane and hydrophilic surface with silica were found to be around 77 degrees and 12 degrees, respectively. Using the difference in wettability for BnSiO3/2 molten liquid between the hydrophobic and hydrophilic surfaces, micropatterns of transparent BnSiO3/2-thick films were formed by the electrophoretic deposition of BnSiO3/2 particles on indium tin oxide substrates with hydrophobic-hydrophilic patterns and subsequent heating above the glass transition temperature.
