Effect of tungsten disulfide nanotubes on crystallization of polylactide under uniaxial deformation and annealing
Tungsten disulfide (WS 2 ) nanotubes (NTs) are examined here as a filler for polylactide (PLA) for their ability to accelerate PLA crystallization and for their promising biocompatibility in relevant to biomedical applications of PLA-WS 2 nanocomposites. In this work, we have studied the structural...

NTs from 0 (neat PLA) to 0.6 wt%. The films were uniaxially drawn at 90 °C and annealed at the same temperature for 3 and 10 min. Using wide angle x-ray scattering, Raman spectroscopy and differential scanning calorimetry, we probed the effects of WS
