A neutron beam, generated from a proton beam with an energy of 26.5 MeV, is used to modify the polymer films annealed at different temperatures, and the effects of neutron irradiation on the crystallinity and ordering of the polymer chains and hence the ferroelectric properties of the films are analyzed. The ferroelectric properties are characterized using piezoresponse force microscopy and polarization-voltage measurements. A comparison of the non-irradiated and irradiated P(VDF-TrFE) films shows that the remnant polarization of the irradiated films increases to 17% owing to the microstructural changes induced in them.

中子辐照对P(VDF-TrFE)薄膜铁电性能的影响

由能量为 26.5 MeV 的质子束产生的中子束用于改性在不同温度下退火的聚合物薄膜，以及中子辐照对聚合物链的结晶度和有序性的影响，从而影响其铁电性能。电影进行分析。铁电特性使用压电响应力显微镜和极化电压测量来表征。未辐照和辐照的 P(VDF-TrFE) 薄膜的比较表明，由于在其中引起的微观结构变化，辐照薄膜的剩余极化增加了 17%。
