Effect of Surface Fluorination of Poly (p-Phenylene Terephthalamide) Fiber

Abstract

Direct fluorination is one of the most important and effective method to modify the polymer surface. It is a simple and fast method that allows the simultaneous treatment of outer and inner surfaces of complex shaped polymeric materials. Poly-p-phenylene terephthalamide fibers which are a very important class of material was surface modified by direct fluorinaton. An extensive characterization of both the virgin and the fluorinated materials were performed by various techniques (XRD, FT-IR, Surface energy and DSC, TGA). From these data, possible effects of fluorination are discussed.
