In this study, the modification induced by CO 2 ‐pulsed laser on the surface morphology of silica–polyacrylonitrile 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 −1 ). 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. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
