| 目的 考察交联剂种类及用量、引发剂用量、聚合温度对聚丙烯酸铕配合物吸水性能的影响，并探讨不同交联剂对聚丙烯酸铕（PAAEu）吸水树脂发光性能的影响。方法 以环己烷和正己烷为连续相，Span-60为悬浮稳定剂，过硫酸钾为引发剂，N, N'-亚甲基双丙烯酰胺（MBA）和EuCl3为交联剂，通过反相悬浮聚合制备聚丙烯酸铕吸水树脂。结果 当交联剂、引发剂分别为单体质量的0.27%，1.3%，聚合温度为68 ℃时，树脂吸水倍率可达491.21；通过热重分析可知，吸水树脂的外延起始温度为333.1 ℃，具有较好的热稳定性；发射光谱测试表明，由MBA与EuCl3 混合交联剂制备的树脂具有较好的发光性能。结论 将MBA与EuCl3混合用作交联剂时，能得到具有较好发光和吸水性能的聚丙烯酸铕配合物吸水树脂。 |

| The work aims to investigate the influence of the type and amount of crosslinker, initiator amount and polymerization temperature on the water-absorbability of poly(acrylic acid) europium(PAAEu) complex and study the influence of different crosslinkers on luminescence properties of PAAEu. The water-absorbent resin of PAAEu was prepared through the inverse suspension polymerization, with cyclohexane and n-hexane as the continuous phases, span60 as the suspension stabilizer, potassium persulfate as the initiator, and N,N'-methylene bin-acrylamide (MBA) and EuCl3 as the crosslinkers. The water absorbency of resin could reach 491.21 when the crosslinker and initiator were respectively 0.27% and 1.3% of the monomer mass, and the polymerization temperature was 68 ℃. In addition, the thermogravimetric (TG) analysis showed that, the extension starting temperature of the water absorbent resin was 333.1 ℃, indicating the good thermal stability. The resin prepared with MBA and EuCl3 as the mixed crosslinker showed good luminescence properties through the emission spectrum test. The water-absorbent resin of PAAEu complex with better properties of luminescence and water-absorbability can be obtained when the mixture of MBA and EuCl3 is used as the crosslinker. |
