Recent advances in fundamental understanding of scratch and mar behavior of thermoplastic olefins
The work conducted over the past decade at Texas A&M in the field of polymer scratch research has led to the development of a standardized scientific research tool. Through its use, significant strides towards understanding the underlying fundamental principles of the deformation of polymeric surfaces have been made. It has been realized that scratch research can be approached from either a mechanistic or an aesthetic standpoint. From a mechanistic view, the focus is on the relationship between mechanical/physical properties and scratch deformation. In the aesthetic approach, the principles of surface/light interaction and human optical physiology are incorporated into a recently-developed software package to automatically detect the onset of scratch visibility. Several case studies will be shared that include not only thermoplastic olefins, but also films, coatings, and nanocomposites.
