摘　　要：针对通常的熔融加工过程中聚偏氟乙烯(PVDF)结晶经常获得不具有压电性的α晶的情况,讨论了制备富含具有良好压电性能β晶的PVDF制品的方法,从纯PVDF,PVDF纳米复合材料,PVDF共混物等方面综述了制备β相PVDF的方法、影响β相含量因素及各种制备方法的利弊,并对其制备方法的趋势进行了展望。According to the conditions that during common melt processing, the crystallization of PVDF generally results in α phase without any piezoelectricity, so the preparation methods of PVDF products with high content of β phase which has good piezoelectricity were introduced. The ways to prepare β phase and the factors that influence the content of β phase from pure PVDF, PVDF nanocomposites, PVDF blends and so on were summarized, the methods to obtain PVDF products with high content of β phase were prospected.
