Abstract
Superhydrophobic surfaces have considerable technological potential for variousapplications due to their extreme water-repellent properties. A number of studies havebeen carried out to produce artificial biomimetic roughness-induced hydrophobicsurfaces. It is not clear whether microstructures or nanostructures or their certaincombination on the surface, are required for superhydrophobicity. A variety of micro- andnanopatterned surfaces of two different polymers, poly(methyl methacrylate) (PMMA) andpolystyrene (PS), were fabricated. We show how static contact angles vary withmicro- and nanopatterns on the polymer surfaces. Based on the experimental dataand a numerical model, the trends are explained. Tribological properties play animportant role in many applications requiring water-repellent properties. Therefore,it is important to study the adhesion and friction properties of these surfacesthat mimic nature. An atomic/friction force microscope (AFM/FFM) was usedfor surface characterization and adhesion and friction measurements. To furtherexamine the effect of meniscus force and real area of contact, scale dependence isconsidered with the use of AFM tips of various radii. The effect of relative humidity isalso investigated to study the environmental effects on adhesion and friction.
