Scratch behavior of epoxy nanocomposites

What is it about?

The effects of nanoscale core-shell rubber (CSR) particles and α-zirconium phosphate (ZrP) nanoplatelet fillers on the scratch behavior of epoxy have been examined using the ASTM scratch testing method. The critical load for onset of microcrack formation is utilized to determine scratch resistance of the epoxy nanocomposites. Optical microscopy and scanning electron microscopy were performed to determine failure and fracture patterns caused by the scratch.

Why is it important?

It is uncertain before if scratch resistance of nanoplatelets and CSR nanoparticles enhanced epoxys would be improved. The present study provides a good understanding of fundamental structure-property relationship of scratch mechanisms of epoxy nanocomposites and establishes guidelines for preparation of scratch resistant polymeric systems.
