摘要: Monolithic carbon scaffolds were obtained by pyrolysis of regenerated cellulose. First, microcrystalline cellulose was compounded, at a 1:1 mass ratio, with 1-ethyl-3-methylimidazolium acetate, choline chloride or mixture the two ionic liquids. Test bars extrusion-molded and liquid removed leaching water. The porous carbonized 800 °C in nitrogen atmosphere. Raman ID/IG peak intensity ratios ranged from 0.74 to unity confirming formation amorphous carbon. Scanning electron microscopy revealed highly structure consisting both micro- nanopores.
