Air-ozonolysis activation of polyolefins versus use of laden finishing to form contact-active nonwoven materials

Abstract Two synthetic approaches were explored for modification of the polyolefins polyethylene/polypropylene (PE/PP) to form contact-active nonwoven materials. In the first approach, polymer surfaces were activated by O2-free air-ozonolysis, and then the active agent (trimethoxysilyl) propyl-octad...
