2g] zone-center mode, and the D and D' bands were ascribed to disorder-induced modes in the PVA-MWCNTs [26, 27], Generally, the degree of MWCNTs' alignment could be evaluated by the ratio of the intensities of G bands in the two polarization directions, GVv/ GvH, which was known as depolarization factor R [28-31].
The increase of melting point, the increase of depolarization factor R in the polarized Raman, and the delay of the crystallization of PVA molecules in the nonisothermal crystallization demonstrated that the interaction between MWCNTs and the matrix in the PVA-MWCNTs/PVA nanocomposites was stronger than in the raw-MWCNTs/PVA nanocomposites.
