Friction behaviour of polymeric material

The understanding of the friction behaviour of the human skin is indispensable in order to optimize surfaces and materials in contact with the skin. The coefficient of friction for different materials contacting against the skin is mainly influenced by the nature of the materials, mechanical contact parameters and physiological skin conditions. The aim of the present research work was to study the grip effect of two different polymeric materials by producing different textured patterns using a 3D printing micro-fabrication technique. It was found that a difference in friction amplitude exists between the two different polymeric materials and that positive texturing showed higher coefficient of friction than negative texturing (that decreases as the textured pattern area density increases).
