Abstract
The crystal structure and morphology of syndiotactic polystyrene (sPS) melt-crystallized in various electrostatic fields have been investigated by using wide angle X-ray diffraction (WAXD), differential scanning calorimeter (DSC) and scanning electron microscope (SEM). WAXD and DSC analyses show that sPS is gradually transformed from a phase to β phase with increase of electrostatic intensity. The SEM observations indicate that the morphology of sPS micro-crystals is strongly dependent on electrostatic intensity applied to the sample during solidification. The variation of the micro-crystals orientation from disordered lamellae to ordered lamellare have been observed with increase of electrostatic intensity.
