Organo-clay hybrid hydrophobic spherical styrene divinyl benzene crosslink beads for high performance carbon dioxide capture

Abstract

We report here the carbon dioxide sorption properties for a series of cloisite containing crosslink hybrid materials.These materials were prepared copolymerizing styrene divinylbenzene in presence of various cloisites through suspension polymerization in one pot in order to obtain uniform spherical beads.The homopolymer formed during the polymerization was separated from the hybrid. The synthetic strategy is user-friendly, cost-effective, and can be easily scaled up for production and shows good mechanical strength. The microporous polymeric spheres containing organo-clay (cloisite) showed a high surface area of ~80 - 370 m2 g-1 with a microspheres size ~4.4 nm. These polymeric spherical beads were hydrophobic and thermally stable up to 300oC. It showed high carbon dioxide uptake (up to ~20.7 wt % at 273K /1.0 bar), due to lone pair electrons of heteroatom, which might sharpen the interaction between the CO2 molecules and polymeric matrices through local-dipole/quadruple interaction. It showed good capacity to store CO2, which is attributed to the presence of quaternary ammonium groups in the clay and a large amount of narrow microspheres (~4.4 nm). The equilibrium CO2 capacities of the prepared spherical beads were due to the interaction between the quaternary ammonium and the negatively charged oxygen atoms of CO2 occurred and showed potential applications in gas adsorption and separation.
