Ion-Energy Dependency in Proton Irradiation Induced Chemical Processes of Poly(dimethylsiloxane)
In this paper, we present a study of chemical changes in poly(dimethylsiloxane) (PDMS) induced by proton irradiation of various energy and fluence. It has been found that the forming products vary as the energy of the proton changes, which means that the
