In this work, we present a simple and fast method for elaborating hybrid membranes by growing metal–organic framework crystals inside a polymer solution. The solution thus obtained was casted then annealed at 90°C for 5 h. This method was tested with poly(vinylidene fluoride) (PVDF) as a piezoelectric polymer and the Cu₃(BTC)₂, BTC = 1,3,5‐benzene tricarboxylate, as a filler. The characterization of the obtained membranes by attenuated total reflectance Fourier transform infrared spectroscopy and X‐ray diffraction showed the presence of the characteristic signatures of Cu₃(BTC)₂ and the β‐phase of PVDF. Moreover, scanning electron microscopy images reveal that the Cu₃(BTC)₂ crystallites have grown along the PVDF membranes. The effect of the filler on both thermal and mechanical properties of the membranes was also studied. POLYM. ENG. SCI., 60:464–473, 2020. © 2019 Society of Plastics Engineers

原位晶体生长制备的聚偏二氟乙烯/ Cu3（BTC）2复合膜的理化性质

在这项工作中，我们提出了一种通过在聚合物溶液中生长金属-有机骨架晶体来制造杂化膜的简单而快速的方法。将由此获得的溶液浇铸，然后在90℃下退火5小时。使用聚偏二氟乙烯（PVDF）作为压电聚合物，并使用Cu ₃（BTC）₂（BTC = 1,3,5-苯三羧酸酯）作为填充剂测试了该方法。通过衰减全反射傅立叶变换红外光谱和X射线衍射对获得的膜进行表征，结果表明存在Cu ₃（BTC）₂的特征标记和PVDF的β相。此外，扫描电子显微镜图像显示，Cu ₃（BTC）沿着PVDF膜生长了_2个微晶。还研究了填料对膜的热性能和机械性能的影响。POLYM。ENG。SCI。，60：464–473，2020.©2019塑料工程师协会
