This study was designed to investigate the effect of nano silica particles on the pressure-sensitive acrylic adhesive bonding on polypropylene film. In this work, the effect of plasma treatment on polypropylene films was examined. Selected variables including plasma treatment time, power and gas type at three levels were considered. Results were analyzed by Taguchi method and optimum condition of high adhesive strength at 7 minutes, power of 100 W and argon gas was obtained. Then varying amounts of silica nanoparticles were added to the acrylic adhesive. Adhesion strength test method was evaluated and the results showed that the strength increases to maximum value at 5.0 weight of nano silica. Functional groups on PP surface following plasma treatment were also detected using ATR- FTIR method; moreover, the etching condition of the surface was examined by both SEM and AFM methods.
