Abstract

This paper presents the study of behavior of storage modulus and glass transition temperature of MWNT/PMMA polymer nanocomposites prepared by solution casting method, with different (0, 0.1, 0.2, 0.3, 0.5, 1, 5, 10) wt% of MWNT in the PMMA matrix. Dynamic mechanical analysis has been done in tension mode. Storage modulus increases with CNT loading in matrix except for 0.1, 0.2 wt% CNT samples, for 0.5 wt% sample onwards to 10 wt% increases continuously, whereas glass transition temperature is found to increase smoothly for all samples, which is explained in terms of the interactions between polymer-MWNT and MWNT-MWNT.Keywords: Nanocomposites, Storage modulus, Glass transition temperature, Dynamic mechanical analyzer
