Descripción
Sumario:Compressibility of liquid flame spray-deposited porous TiO(2) nanoparticle coating was studied on paperboard samples using a traditional calendering technique in which the paperboard is compressed between a metal and polymer roll. Surface superhydrophobicity is lost due to a smoothening effect when the number of successive calendering cycles is increased. Field emission scanning electron microscope surface and cross‒sectional images support the atomic force microscope roughness analysis that shows a significant compressibility of the deposited TiO(2) nanoparticle coating with decrease in the surface roughness and nanoscale porosity under external pressure.
