英文摘要	利用γ射线辐照引发含双键的丙烯酸12冠4醚酯(V12C4)与丙烯酰胺(AM)发生共聚和交联反应,制备了新型的聚丙烯酰胺-丙烯酸12冠4醚酯(PAM-12C4)水凝胶.采用凝胶分析,显微红外,热重分析对PAM-12C4进行表征,并考察了PAM-12C4对水溶液中Li+的溶胀度响应性.研究表明,γ射线辐照可成功引发V12C4与AM发生共聚及交联反应,辐照至吸收剂量10 kGy时得到PAM-12C4的凝胶分数为94%.该新型含冠醚基团的水凝胶具有良好的热稳定性,在水溶液中对Li+具有明显的选择性溶胀度响应.; A novel poly-(acrylamide-co-vinyl-12-crown-4-ether) (PAM-12C4) hydrogel with a specific lithium- ion-response was synthesized via radiation-induced copolymerization and cross linking. The resultant PAM-12C4 was characterized by gel fraction, micro-FTIR spectroscopy, and thermo gravimetric analysis (TGA). The swelling behavior of PAM-12C4 in a lithium salt solution was also studied. The results showed that the PAM-12C4 hydrogel was successfully synthesized with a gel fraction of 94% at a dose of 10 kGy. The resultant PAM-12C4 hydrogel exhibits good thermal stability and gives an obvious response to the lithium-ion in an aqueous solution.; 国家自然科学基金项目(U1430324)资助; 中国科学引文数据库(CSCD); 4; 40-45; 35
