摘　　要：近年来,随着人类社会的高速发展,全球化石燃料资源大幅下降,现有的能源储量逐渐无法满足社会发展需求,因此,将自然界中无法利用的能量转换为可再生能源成为了研究热点。压电高聚物作为压电材料的重要组成部分,具有高强度、高柔性和对电压的高度敏感性,可以将自然界中的机械能、热能、声能和振动能转化为电能,在纳米发电机、传感器、生物医学等领域有着很大的潜力。但大多数压电高聚物存在着居里温度低的问题,因此研制新型耐高温的高聚物是目前的重要发展方向。首先针对几种广泛使用的压电高聚物(聚偏氟乙烯、尼龙11和聚丙烯腈)的研究进展进行了介绍,然后基于这些材料耐高温性能的发展进行了论述。In recent years,with the rapid development of human society,the global fossil fuel resources have declined significantly,and the existing energy reserves are gradually unable to meet the needs of social development.Therefore,it has become a research hotspot to convert the energy that cannot be used in nature into renewable energy.As an important part of piezoelectric materials,piezoelectric polymer has high strength,high flexibility and high sensitivity to voltage.It can convert mechanical energy,thermal energy,sound energy and vibration energy in nature into electric energy.It has great potential in nanogenerators,sensors,biomedicine and other fields.However,most piezoelectric polymers have the problem of low Curie temperature,so developing new high temperature resistant polymers is an important development direction at present.In this paper,the research progress of several widely used piezoelectric polymers(polyvinylidene fluoride,nylon 11 and polyacrylonitrile)is firstly introduced,and then the development of high temperature resistance of these materials is discussed.
