32.Sulfonic acid functionalization of 2-aminoterephthalate metal−organic framework and silica nanoparticles by surface initiated radical polymerization: as proton-conducting solid electrolytes

What is it about?

A post-polymerization method for metal–organic frameworks (MOFs) and silica nanoparticles have been developed to produce super-acidic solid nanoparticle. Thus, silica and amino-functionalized metal−organic framework [NH2-MIL-101(Al)] were functionalized with 4.4′-Azobis(4-cyanovaleric acid) (ACVA) from hydroxyl and amine groups to yield initiator anchored silica and MOF nanoparticles. Then, sulfonated polymer/MOF and sulfonated polymer/silica hybrid nanoparticles were prepared by free radical polymerization of 2-acrylamido-2-methyl-1-propane sulfonic acid [(MOF-g-PAMPS) and (Si-g-PAMPS)], initiated onto the surfaces of initiator functionalized nanoparticles.
