Abstract

CNT were dispersed in an epoxy matrix and cured by means of UV light. An increase on elastic modulus and Tg values was measured by DMTA anal. and attributed to the constraint effect of CNT on polymer chain mobility. Excellent scratch resistant coatings characterized by high crit. load, small cracks and high recovery were obtained in the presence of a very low CNT content (0.025 wt.-%). TEM anal. showed some isolated CNT and some cluster agglomerations of size of about 250 nm. It was shown that it was possible to decrease the surface resistivity of the cured samples by three orders of magnitude in the presence of 0.1 wt.-% of SWCNT content.
