摘要
Abstract
A novel poly(ionic liquid) which can be used as a carbon precursor was synthesized using a one-pot reaction using 1, 2-dimethylimidazole and epichlorohydrin as starting materials. The unique features of this poly( ionic liquid) include:no additional initiator is required;anions can be metathesized to regulate the micropore size of the carbonaceous materials. Carbonaceous materials derived from the poly( ionic liquid) with chloride anions ( Cl-) as counter ions have a low surface area of 47 m2/g. However, by re-placing Cl-with a bulky bis( trifluoromethylsulfonyl) imide ( TFSI-) anion, the carbonaceous materials produced have a high surface area of 595 m2/g, while replacing Cl- with dicyanoimide (N(CN)2-) anion results in a reduced surface area of 30 m2/g.关键词
