V. Svorcik et al., SURFACE MODIFICATION OF POLYETHYLENE AND POLYPROPYLENE BY ION-IMPLANTATION, Journal of applied polymer science, 49(11), 1993, pp. 1939-1942
The creation of oxidized structures and double bonds in polyethylene (
PE) and polypropylene (PP) samples implanted with P+ ions was studied.
The surface polarity and the electrical conductivity of the ion-impla
nted polymers were also examined. As a result of the ion implantation,
the polymer macromolecules are broken up and the material is degraded
. An oxygen penetration into the radiation-damaged polymers is also ob
served, with PE being more vulnerable to the oxidation. The ion-implan
ted PP exhibits higher surface polarity and sheet conductivity compare
d to that of PE. (C) 1993 John Wiley & Sons, Inc.
