Doppler broadening studies of surface-modified conducting polyethylene

Description

Carbon doped, conducting polyethylene has been studied by positron techniques: bulk lifetime and depth-resolved doppler broadening analysis. Lowering of the Doppler broadening S-parameter has been observed for samples just at percolation threshold. Chemical modifications reduce diffusion of positrons in near surface layers. Doping with carbon does not change free-volumes, as monitored via long component of positron lifetime spectrum. (author). 7 refs, 3 figs
