Abstract
Polymerized high internal phase emulsion of poly (DVB) polyHIPE filled with maleimide-terminated poly (arylene ether sulfone) oligomers (M-PSO) has been successfully prepared using high internal phase emulsion technique. Poly (DVB) polyHIPE filled with maleimide-terminated poly (arylene ether sulfone) oligomers (0, 2.5, 5, and 10 wt%) were prepared using SPAN80:DDBSS:CTAB (6.3:0.4:0.3) as mixed surfactant. The obtained polyHIPE foams were characterized for their phase morphology, surface area, thermal behaviour, and mechanical properties using SEM, BET, TG/DTA, and a LLOYD Universal Testing machine, respectively. The prepared polyHIPE foams will be used for adsorbing the CO2 produced during the gasification process to increase the heating value of syn gas. Phase morphology of the obtained polyHIPE foams showed an open cellular structure with small interconnectivity. The mechanical properties and decomposition temperatures (Td) increased with increasing filler content from 0 to 10 wt%. The adsorption of CO2 gas by poly (DVB) polyHIPE foam filled with maleimide-terminated poly (arylene ether sulfone) oligomer was found to increase as well (from 3.125 to 3.459 mmol/g) when compared with neat poly (DVB) polyHIPE foam.
