Fig. 7From: Effect of tungsten disulfide nanotubes on crystallization of polylactide under uniaxial deformation and annealingNormalized Raman intensity of 924 cm− 1 and 1454 cm− 1 PLA bands measured in the spectra of UNST, ST0, ST3, ST10 films of PLA and PLA-WS2 nanocomposites. The data are normalized with respect to the intensity of the PLA band at 1095 cm− 1Back to article page
