Stick-slip phenomena and its influence on polymer scratch
The stick-slip phenomenon is commonly observed during polymer scratch process. The occurrence of stick-slip and its characters are controlled by many factors according to previous analytical study. It is believed the stick-slip will change the surface roughness which eventually induces the scratch visibility. Both ASTM and Erichsen test methods are employed to study the loading effect of stick-slip phenomenon during polymer scratch. The influence of stick-slip phenomenon on scratch performance is studied. Possible solutions to minimize the occurrence of stick-slip phenomena thus improve the scratch resistance of polymeric material are also discussed.
