- Abstract
The preirradiation grafting of acrylic acid AA onto polyethylene terephthalate PET had been found to affect the thermal and physical characteristics of fabric. The grafted fabrics with various graft levels were characterized by thermal gravimetric analysis TGA, ATRFTIR spectroscopy, contact angle, differential scanning calorimetry DSC, Xray diffraction XRD, atomic force microscopy AFM, and scanning electron microscopy SEM. The initial decomposition temperature and T50were increased with the increase in degree of grafting. The percentage crystallinity was decreased as the degree of grafting increases. The detailed elemental analysis was done by Xray photoelectron spectroscopy XPS. The atomic ratio O1sC1s was found to increase significantly with increasing the degree of grafting and reached 0.64 at 14.5 grafting from 0.38 for virgin PET. The surface topography and morphology was strongly influenced as the degree of grafting was increased. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
