摘要
用 WAXD、DSC和 SEM研究了高真空强静电场下熔融结晶的间规聚苯乙烯晶体结构和形态。实验发现 ,随电场强度的增大 ,间规聚苯乙烯晶体逐渐由 α相向 β相转变 。
The structure and morphology of syndiotactic polystyrene (sPS) melt crystallized in high vacuum electrostatic fields has been respectively investigated by using WAXD, DSC and SEM. The results show that sPS crystals gradually changes from α phase to β phase with increase of electrostatic intensity. The crystal orientation and variation of the crystals from disordered lamellar crystals to ordered lamellar crystals with increase of electrostatic intensity were observed.
