Salient Features of Amorphous Fraction Dynamics in Stretched Poly( l -lactic acid)
Melt pre-deformation is widely used to tailor the morphology and properties of semicrystalline polymers, yet its influence on the dynamics of the amorphous fractions remains poorly understood. Here, we investigate the evolution of the rigid amorphous fraction (RAF) and mobile amorphous fraction (MAF) in semicrystalli...
