Synthesis and Properties of Ethylene Imine-Based Porous Polymer Nanocomposites with Metal Oxide Nanoparticles
Ethylene imine-based porous polymer nanocomposites were prepared by ring-opening polymerization of 2,2-bishydroxymethylbutanol-tris [3-(1-aziridinyl)propionate] (3AZ), a tri-functional aziridine compound, in the presence of commercially available metal oxide nanoparticles, SiO<sub>2</sub> or ZrO<sub>2</sub>, accompanied by polymerization-induced phase separation. The reactions with SiO<sub>2</sub> and ZrO<sub>2</sub> nanoparticles successfully yielded nanocomposite porous polymers as rigid materials. The nanocomposite porous polymers with SiO<sub>2</sub> and ZrO<sub>2</sub> nanoparticles showed characteristic surface morphologies composed of gathered particles with diameters less than 1 micrometer. These nanocomposites were effective in increasing Young's moduli of the porous polymers due to an increase in their bulk densities. The presence of SiO<sub>2</sub> and ZrO<sub>2</sub> nanoparticles in the porous polymers efficiently retarded thermal decomposition.
