Surface modification of silica–PAN composite nanofibers induced by CO₂‐pulsed laser

Abstract

In this study, the modification induced by CO 2 -pulsed laser on the surface morphology of silicapolyacrylonitrile composite nanofibers has been investigated. Applied surface modification method is based on different infrared adsorption of materials. Two types of composite nanofibers containing silica nanoparticles with various diameters are irradiated with CO 2 -pulsed laser of 1084 wavenumber (cm À1 ). Surface morphology of irradiated composite nanofibers was analyzed using field emission scanning electron microscope (FE-SEM). FE-SEM scans show characteristic modification on the surface of nanofibers with controlled distribution and dimension.

Comparative study of gamma and ion beam irradiation of polymeric nanocomposite on electrical conductivity

“…For the mechanism of conductivity, two important considerations must be one observed the movement of electrons along the electrical paths and the second focuses on the formation of electrical paths through the composite samples. The two mechanisms are dependent on the filler content …”
