Single-cantilever mode of the dynamic mechanical analyzer
(DMA Q800, TA Instruments) was used to measure the storage modulus (E0) and glass transition temperature (Tg, peak temperature in the Tan Delta curve) of the nanocomposites by heating the specimen from 30 to 250 C with a ramping rate of 3 C/min, a frequency of 1 Hz and an oscillation amplitude of 20 mm.
