摘要:
为获得高性能、易便携的柔性湿度传感器,以1,6己二醇二丙烯酸酯(HDDA)为交联剂,将不同摩尔质量比的聚电解质2(二甲氨基)甲基丙烯酸乙酯季铵盐(DEB)与甲基丙烯酸甲酯(MMA)通过紫外光固化交联反应负载在聚乳酸熔喷非织造材料(Polylactic acid meltblown nonwovens material,PLA MB)表面,制得聚电解质@PLA熔喷非织造材料(DEB/MMA@PLA MB)柔性湿度传感器,并探讨DEB和MMA的摩尔质量比对柔性湿度传感器的形貌、组成、传感性能和力学性能的影响。结果表明:经过紫外光固化交联反应后,DEB/MMA在PLA MB表面可均匀成膜;当DEB与MMA摩尔质量比为1∶2时,DEB/MMA@PLA MB传感器在相对湿度10%~90%条件下,传感性能良好、线性关系良好且响应时间短(10~80 s);在高湿环境(相对湿度53%~91%)下,其响应时间仅为10 s,且具有静态稳定性和较好的动态稳定性;与原PLA MB相比,DEB/MMA@PLA MB柔性湿度传感器的拉伸强度有所下降,但断裂伸长率显著提高。该文有望可为生物可降解PLA MB在传感器制备方面的应用提供参考。
