摘要

摘要:
采用一步法合成新型离子液聚合物，并以聚合物作为炭材料的前驱体。这种新型离子液聚合物的特征包括：聚合无需添加引发剂，聚合引入的阴离子能够控制材料的微孔大小。以含Cl^- 的离子液聚合物为前驱体合成的炭材料具有较小的比表面积（47m²/g），而以含较大(三氟甲基磺酰基)亚胺基阴离子的离子液聚合物为前驱体合成的炭材料具有较大的比表面积(595m²/g)。含二氰胺阴离子的离子液聚合物为前驱体合成的炭材料的比表面积为30m²/g。

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 47m²/g. However, by replacing Cl^- with a bulky bis(trifluoromethylsulfonyl)imide (TFSI^-) anion, the carbonaceous materials produced have a high surface area of 595m²/g, while replacing Cl^- with dicyanoimide (N(CN)2^-) anion results in a reduced surface area of 30m²/g.
