Abstract

Poly(vinylbenzylchloride/divinylbenzene); by high internal phase emulsion (poly(VBC/DVB)HIPE) was functionalized with diamines (ethylenediamine, piperazine, aminopiperidine, and imidazole) to improve carbon dioxide adsorption capacity. The amine group in the poly(VBC/DVB)HIPE was confirmed and quantified by Fourier transform infrared spectroscopy and elemental analysis. The surface area, pore size, and pore volume of the materials, after being functionalized with amines, were reduced. The order of the amine loading in the materials was ethylenediamine > piperazine > aminopiperidine > imidazole. The CO2 adsorption capacities were 2.18, 0.83, 0.66, and 0.39 mmol/g.m2.mol amine for the polyHIPE materials of ethylenediamine, piperazine, aminopiperidine, and imidazole, respectively.
