SurfaceFilmFormation Behavior of Modified Polypropylene

Polypropylene(PP) was mixed with the modifiers to improve its wettability. Results showed that the filmforming ratio of modified PP after immersion increased significantly from about 19.9% to 94.4%, and the immersion had little effect on neat PP. Invasion work became positive after wetting modification, so liquid film was stable on the surface, and the liquid flow on the plane was also stable.
