Adhesion Properties of Metal-Filled Functionalized Polypropylene-Based Nanocomposites.

The influence of the filler concentration and the type of compatibilizer on the peeling resistance of polypropylene-based nanocomposites is considered. The filler was aluminum and copper nanoparticles, the substrate was copper and aluminum foil, and the compatibilizer was a polypropylene graft copolymer with 5.6 wt % of maleic anhydride and a polypropylene graft copolymer with 7.0 wt % of methacrylic acid. The filler concentration was varied within 5–50 wt %. It was found that polypropylene nanocomposites containing 10 wt % of filler have relatively high values of peel resistance. The main factors influencing the mechanism of adhesive contact and the type of adhesive destruction, which result in high values of resistance to peeling of the adhesive from the foil surface, are revealed.
