Carbon nanotubes are one of the preferred fillers for polymer composites due to their exceptional electrical and mechanical properties. In this work, we would like to present the detailed study on reinforcement effects of polymer thin films against high energy radiations when the various amount of CNT fillers are introduced. By the irradiation of short wavelength ultraviolet(UV) light with ozone and electron beams, the surface modification and stripping effects on their CNT/PMMA thin films are studied as a function of weight % of CNT in PMMA matrices. The experimental evidence indicates that the presence of CNT in PMMA matrix lowers significantly the stripping rate of the composite materials. The results are then correlated with systemic study of the rheological and chemical properties of PMMA/CNT composites by thermal analysis (i.e. TGA and DSC), and spectroscopic techniques.
