摘　　要：通过丙烯酰胺与2-丙烯酰胺-2-甲基丙磺酸自由基共聚的方法制备了一种具有良好机械性能的纳米黏土/稀土复合发光水凝胶材料,稀土Eu^(3+)通过离子交换被引入到纳米黏土上,通过引入噻吩甲酰三氟丙酮(TTA)配体,从而得到了具有优异发光性质的水凝胶。该水凝胶是一种对酸碱敏感的发光材料,可在甲酸及三乙胺的蒸汽条件下实现荧光的可逆响应。In this paper,a kind of nano clay/rare earth composite luminescent hydrogel material with good mechanical properties was prepared by free radical copolymerization of acrylamide and 2-acrylamide-2-methylpropane sulfonic acid.The hydrogel is an acid base sensitive luminescent material,which can achieve reversible fluorescence response under the condition of formic acid and triethylamine vapor.
