高含量β相PVDF薄膜的制备技术及相形成机理研究进展
Research progress on preparation technology and phase formation mechanism of PVDF films with high β phase content
摘要
Abstract
Piezoelectric materials are widely used in electronic devices such as filters,micro-shifters,actuators and sensors,and also play an important role in high-tech fields such as satellite broadcasting,electronic equipment,biology and aerospace.Piezoelectric materials are mainly divided into monocrystal piezoelectric materials,polycrystalline piezoelectric materials,polymer piezoelectric materials and polymer-piezoelectric ceramic composite materials.Polymeric piezoelectric materials such as PVDF have good flexibility,excellent thermoelectric and ferroelectric properties,so they have been widely concerned.In this paper,the preparations of PVDF with high β phase content by solution casting,electrospinning and drawing are introduced.The influence of process types and process parameters on β phase formation were pointed out,and the mechanism of phase transformation under different processing technologies was discussed.The preparation technology,phase formation mechanism and application trend of high content β phase PVDF films are also prospected.关键词
