PEPA/PVA hydrogel microporous material with fluorescence humidity sensing function and preparation method thereof

The invention discloses a PEPA/PVA hydrogel microporous material with a fluorescence humidity sensing function and a preparation method of the PEPA/PVA hydrogel microporous material. The PEPA/PVA hydrogel microporous material is prepared through a simple operation method of freeze-thaw cycle, and compared with a traditional fluorescent hydrogel material, the PEPA/PVA hydrogel microporous material has the advantages that the fluorescence characteristic of the PEPA/PVA hydrogel microporous material has specific sensitivity to microenvironment humidity change, and the PEPA/PVA hydrogel microporous material has a recycling function, so that the application performance and the field of an NTIL material are greatly expanded. 本发明公开了一种具备荧光湿度传感功能的PEPA/PVA水凝胶微孔材料及其制备方法。本发明通过冻融循环这种简单的操作方法制备了PEPA/PVA水凝胶微孔材料，与传统荧光水凝胶材料相比，PEPA/PVA水凝胶微孔材料荧光特性对微环境湿度变化具有专一敏感性，并且具备循环使用功能，从而极大拓展了NTIL材料应用性能与领域。
