摘要：

Several techniques have been applied to the surface of polypropylene (PP) film to improve its adhesion properties: grafting of poly(acrylic acid) by peroxidation after either irradiation by gamma-rays or activation by argon plasma, acrylic acid plasma polymerization and nitrogen plasma. A first evaluation of their efficiency was made by measuring the adhesion energy of a two-layer complex containing the modified PP film and an acrylic adhesive tape. Grafting of poly(acrylic acid) either by pre-irradiation or by argon plasma treatment did not give a satisfactory improvement of the adhesion. On the contrary, nitrogen as well as acrylic acid plasmas induced a peeling energy that was up to 10 times higher than the value obtained for an untreated PP film towards the acrylic adhesive tape. The adhesion of PP films was also tested on bilayer laminates with (a) an extrusion-oxidized polyethylene film and (b) a terpolymer film of ethylene, acrylic acid and acrylate. Good adhesion was achieved between nitrogen-plasma-treated PP film and the oxidized polyethylene film (600 J m(-2)) as well as the terpolymer film (427 J m(-2)). However, the poly(acrylic acid) plasma-deposited layer induced an improvement of the adhesion only with the preoxidized polyethylene film (390 J m(-2)).
