Published in 2018 at "High Energy Chemistry"

DOI: 10.1134/s0018143918050132

Abstract: Energy characteristics of the irradiated surface of a polytetrafluoroethylene film depend on the energy and fluence of bombarding MeV protons. Irradiation with 2–4 MeV protons leads to an increase in the surface free energy; 4… read more here.
