Effect of surface treatment on polypropylene film-oil interactions

The results are being presented of an investigation to explore the possibility of using surface modification of biaxially oriented polypropylene (BOPP) film in the control of some polymer-oil interactions. The deposition of thin-film polymer structures by means plasma polymerization of styrene in r.f. glow discharges have been used as a method of polymer surface treatment. The change of some characteristics of polypropylene after treatment and effect of use of plasma polymer coating on polymer-oil interaction as well as on resulting dielectric properties of polymer-oil system have been investigated.
