1,4-Bis(Imidazol-1-yl)butane was used to modify SBA-15,SBA-15prIm2Cl was obtained.SBA-15prIm2C4Cl and SBA-15prIm2C8Cl were obtained by extending the length of alkyl chain.
石墨烯/氧化石墨烯(G/GO)作为一类明星材料,已广泛用于能源材料、海水淡化、药物输送、生物传感及成像等诸多领域[1-2],并显现了超乎传统材料的优越性质。遗憾的是无论采取Top-Down 还是Bottom Up 方法都很难制备出完美无缺的石墨烯,而G/GO 表面官能团特别是羧基官能团会严重影响其物理化学性质以及进一步应用,如石墨烯表面极微量的羧基就会严重影响其导电或导热性质。
