Surface Morphology Study on Fibres Treated in Cold Plasma Discharge

Abstract:

The paper presents results related to surface treatment of polypropylene fibres with intention to increase its performance in cement composite by exposing such fibres in cold plasma discharge. In was previously demonstrated that such treatment has beneficial effect. Here we focused mainly on the changes in the surface. The study was carried out by electron microscopy, confocal microscopy and microscopy of atomic forces. The results suggest increasing degree of change in the surface as the energy of discharge and time of exposure increase. Atomic force microscopy indicates increase in adhesion force.
