Surface static properties of plasma treated FRP

This study on comparative analysis of the surface degradation mechanism through measurement of chemical and electrical changes was conducted to explain the surface degradation of FRP (fiber reinforced polymer) resulting from a plasma interaction and degradation process. Chemical and electrical analysis of a macromolecular surface subjected to plasma treatment shows that a hydrophilic surface is caused by the generation of radicals containing the -COO group, on the surface of which the static balance is destroyed rapidly to become positive.
