High CO2 Adsorption Polymeric Foam from Poly(DVB)PolyHIPE Filled with Maleimide-Terminated Poly(Arylene Ether Sulfone) Oligomers via High Internal Phase Emulsion

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.

Organoclay derived from Na-bentonite can offer an alternative used as an inorganic filler for high internal phase emulsiom foams. Two types of organoclay, hybrid organic–inorganic porous clay heterostructures (HPCH), derived from organo–bentonite which prepared through surfactant–directed assembly of tetraethoxysilane (TEOS)/methyltetraethoxysilane (MTS) into galleries of the clay mineral, and organo-modified bentonite (MOD) treated with quaternary alkyl ammonium cation by ion exchange reaction, were used as a reinforcing agent for poly(divinylbenzene; DVB)polyHIPE foams in this study. Poly(DVB)polyHIPE foams filled with organo-bentonite (MOD and HPCH) loadings of 0, 1, 3, 5, and 10 wt% were successfully prepared using the HIPE technique. To study the effects of the organoclay on morphology, surface area, and mechanical properties of the prepared poly(DVB)polyHIPE foams, SEM, N2 adsorption-desorption, and a Lloyd Universal testing machine were employed. It was demonstrated that the addition of organo-bentonite (both MOD and HPCH) into PolyHIPE foams resulted in the enhancement of physical properties of the poly(DVB)polyHIPE foams. The incorporation of layered silicate in the polymer matrix were supported by SEM images, which shown that the roughness of the polymer wall surfaces appeared to increase due to the presence of organoclay. It was established that the use of organo–bentonite, both HPCH and MOD, as inorganic filler for poly(DVB)polyHIPE, has an effect on improving the surface area of the obtained materials. However, higher improvement in surface properties was achieved with poly(DVB)polyHIPE filled with HPCH when compared with poly(DVB)polyHIPE foams filled with MOD. This is because of the surface charateristic of the HPCH which is a combination of micro– and mesoporosity between each layered of silicates and gas molecules might be able to adsorbed into these porous structures. Mechanical properties of the filled poly(DVB)polyHIPE foams were found to improve when compared to the neat poly(DVB)polyHIPE. Highest Young’s modulus and compressive stress were observed at 5 wt% organoclay loading. It was clearly demonstrated in this study that the suitable content of

Comonomer Content

The effect of enhancing the crosslinking degree in polyHIPEs made from dicyclopentadiene by additionally using a crosslinking comonomer is described. Foams of 80% porosity with 10-40 w% comonomer content in the continous phase are prepared and show similar porosities and morphological characteristics as foams prepared with dicyclopentadiene alone. Assessing the mechanical properties reveals that the ductility is decreasing while the stiffness of the samples is increasing with increasing comonomer content. The foams containing the crosslinking comonomer take up at least five fold mass of toluene therby swelling to at least 30 v%. Upon drying of the swollen specimens, their initial shap and porosity are recovered. This feature distinguishes them from polyHIPEs made from dicyclopentadiene only.<br>

PolyHIPEs are highly porous polymeric form, prepared through emulsion templating by polymerizing the continuous phase of high internal phase emulsions (HIPEs). A maleimide-terminated aryl ether sulfone oligomer (MAPES) was copolymerized with divinylbenzene (DVB) in the continuous phase, using a mixed surfactants system (sorbitan monooleate (Span80), cetyltrimethylammonium bromide (CTAB), dodecylbenzenesulfonic acid sodium salt (DDBSS)), and peroxide initiator, to improve CO2 adsorption and the mechanical properties of obtained materials. PolyHIPEs were prepared by two different ratios of mixed surfactants; (SPAN80, DDBSS, and CTAB; 6.3, 0.4, and 0.3 wt%, which was denoted as 7s) and (SPAN80, DDBSS, and CTAB; 11.3, 0.4, and 0.3 wt%, which was denoted as 12s). 0, 2.5, 5, 10, 20, and 30 wt% of maleimide-terminated aryl ether sulfone oligomer were copolymerized with DVB. All PolyHIPE nanocomposites foam were characterized for phase morphology, thermal behavior, surface area, mechanical properties and adsorption of CO2 by using SEM, TG-DTA, N2 adsorption-desorption, LLOYD universal testing machine and CO2 adsorption unit, respectively. The obtained PolyHIPEs showed an open cell and a secondary pore structure with surface areas of approximately 400m2/g. CO¬2 adsorption tests were characterized by pilot gasification unit and the obtained materials showed higher adsorption than neat poly(DVB) without MAPES. Compressive modulus test of the materials showed a higher modulus than for poly(DVB) PolyHIPEs.
