Physico‐Chemical Characterizations of Poly(vinylidene fluoride)/Cu₃(BTC)₂ Composite Membranes Prepared by In Situ Crystal Growth

Abstract

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

Synthesis of a novel Zn‐MOF/PVA nanofibrous composite as bioorganic material: Design, systematic study and an efficient arsenic removal

“…Inorganic materials with combination of functionalized polymers are very interesting way to achieve advanced properties in field of chemistry and material science. [1][2][3][4][5][6][7] Metal organic frameworks (MOFs) along with polymerization have shown a large extent of porosity and a high surface area in for catalysis, energy storage devices and membrane for gas separation, ion exchange, and biomedical applications. [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] In recent years, heavy metal pollution has increased as a result of the evolution of the chemical industry and the introduction of toxic compounds into water.…”
