摘要: A post-polymerization method for metal–organic frameworks (MOFs) has been developed to produce super-acidic solid nanoparticles. Thus, the NH2MIL-53(Al) MOF was functionalized with (3-aminopropyl)triethoxysilane (APTES) from amine groups yield active site anchored Then, sulfonated polymer/MOF hybrid nanoparticles were prepared by redox polymerization of 2-acrylamido-2-methyl-1-propane sulfonic acid (MOF-g-PAMPS), initiated onto surfaces aminopropyl-functionalized The synthesis and modification characterized Fourier transform infrared (FTIR) spectroscopy TGA. FTIR TGA results indicated that APTES modifier agent AMPS monomer successfully grafted grafting efficiency PAMPS polymer estimated thermograms be 33%. Also, showed a proton conductivity as high 4.9 × 10−5 S cm−1. Nitrogen adsorption modified also decrease in pore volume. morphology crystalline structure before after processes studied SEM XRD, respectively. © 2015 Society Chemical Industry
