And polarizing microscope, wide-angleX-raydiffraction (WAXD) and differential scanning calorimeter (DSC) were used to study the crystalline of PLA membranes prepared at different conditions.
The change of the crystalline structure of UHMWPE fiber was studied by small angleX-ray scattering (SAXS) , wideangleX-raydiffraction ( WAXD) and Raman spectroscopy.
