摘要 采用新型的前端聚合反应模式,成功地制备了聚(N-羟甲基丙烯酰胺-co-二甲基二烯丙基氯化铵)(聚(NMA-co-DMDAAC))水凝胶材料。考察了单体比例对前端反应过程以及产物溶胀性能的影响。随着DMDAAC质量分数由0增大至30%,前端速度由0.83 cm/min降至0.38 cm/min,前端最高温度由97℃降低至77℃,而产物的溶胀率则由原来的291.7%增大至4 014.2%。借助于聚(NMA-co-DMDAAC)水凝胶对量子点的有效吸附,进一步成功制备了具有荧光性能的CdTe/聚(NMA-co-DMDAAC)荧光复合材料。实验表明该复合材料的荧光性能随着其溶胀缩水性能的改变而产生变化,因而在湿度"开关"器件方面有潜在的应用。 The poly(N-methylolacrylamide-co-dimethyl diallyl ammonium chloride)(poly(NMA-co-DMDAAC)) hydrogels have been successfully synthesized using frontal polymerization.The effects of NMA/DMDAAC ratio on the frontal polymerization and the swelling ratio(SR) of the products were explored as well.As the mass fraction of DMDAAC enhances from 0 to 30%,the frontal velocity decreases from 0.83 cm/min to 0.38 cm/min and the front temperature decreases from 97 ℃ to 77 ℃,while the SR of the hydrogels increases from 291.7% to 4 014.2%.The fluorescent CdTe/poly(NMA-co-DMDAAC) hydrogels have been prepared with the aid of the excellent adsorption performance of the poly(NMA-co-DMDAAC) to CdTe quantum dots.This functional hydrogel exhibits obvious luminescence switching behavior through altering the process of swelling and deswelling,which can be developed as QD-based moisture sensor.
