Cellulose-based ionic porous material compatibilized with polymeric ionic liquid was prepared by means of templating technique using oil/ionic liquid emulsion in the presence of sorbitane monooleate. In situ polymerization of a mixture of polymerizable ionic liquids, 1-(3-acryloyloxypropyl)-3-methylimidazolium and 1-(3-acryloyloxypropyl)-3-vinylimidazolium bromides was first performed in a solution of cellulose in a solvent of an ionic liquid, 1-butyl-3-methylimidazolium chloride. The sonication of the mixture coexisting with corn oil and sorbitan monooleate, followed by the successive treatment with methanol, acetone, and hexane gave the porous material. The material thus obtained was characterized by the FT-IR, TGA, XRD, and SEM measurements. The SEM images of the material showed the morphology of the porosity with the pore sizes of around 0.15-1.3 mu m accompanied with the smaller sizes of 30-70 nm.
