Effect of Biopolymer Loading into High Porosity Polymer Adsorbent for Carbon Dioxide Adsorption

摘要

The effect of biopolymer (BP) on polymer obtained from high internal phase emulsion (HIPE) polymerization was studied. Divinylbenzene (DVB) and mixed surfactants were used in emulsion preparation. More BP could be added to the poly(DVB)HIPE when the amount of mixed surfactant was increased. The highest possible BP wt% in the BP-poly(DVB)HIPE was 77 wt%. The structure of polyHIPE before and after loading BP showed a highly interconnected pore network. The surface area decreased when the amount of BP increased. The CO2 adsorption capacity of BP-poly(DVB)HIPE was measured to be 0.173 mmol/g in the moisturized condition.
