以糠醇(FA)、4,4-双马来酰亚胺二苯基甲醇(BM)、BM与二乙烯基苯共聚物(BM-DVB)和蔗糖(S)为炭前驱体,硅胶为硬模板制备了六种纳米孔炭。在氦气气氛中800℃～1 000℃炭化30 min,炭化后利用质量分数40%HF脱除模板。利用元素分析、氮气吸附、热分析和漫反射红外表征产物的孔结构和化学结构及它们对多孔炭热性能的影响。结果表明,前驱体对多孔炭的性能有一定的影响。前驱体的化学结构和热处理条件对炭的孔隙结构,亲水性和热稳定性都有影响。最稳定的产物中含有氮和磷元素。
Using carbon tetrafluoride (FA), 4,4-bismaleimidodiphenylmethane (BM), BM with divinylbenzene copolymer (BM-DVB) and sucrose Template prepared six kinds of nanoporous carbon. Curing in a helium atmosphere at 800 ℃ ~ 1000 ℃ for 30 min, carbonization and then removing the template by mass fraction of 40% HF. The pore structure and chemical structure of the products were characterized by elemental analysis, nitrogen adsorption, thermal analysis and diffuse reflectance infrared spectroscopy and their effects on the thermal properties of porous carbon. The results show that the precursor has a certain impact on the performance of porous carbon. The chemical structure and heat treatment conditions of the precursor have an impact on the pore structure, hydrophilicity and thermal stability of the carbon. The most stable product contains nitrogen and phosphorus.
