    Abstract In this work, the mechanical and barrier properties were examined for Polypropylene (PP) film in which the surface of the film was modified by Oxygen plasma treatment. The PP film was treated in various intervals of time of 60 s, 120 s, 180 s, 240 s and 300 s with three various RF power settings of 7.2 W, 10.2 W, 29.6 W. The contact angle was measured to characterize the wettability. The oxygen functional groups were generated on the surface of oxygen modified PP which was observed by Fourier

  • The Importance Of Wettability

    Wettability can be defined as the extent of intimate contact between liquid and solid. Many factors may affect the wettability like melting temperature, pre heating temperature, reinforcement material, amount, size, stirring speed, stirring time etc. Poor wettability can deteriorate the mechanical properties, wear resistance as well as corrosion resistance of the material. For better load transfer, the wettability of particle should be high (Prabu et al., 2006). (Hashim et al., 1999) concluded that
