| 中文摘要: |
| 基于磺酸咪唑鎓离子对修饰配体构筑一例新型铜基金属有机框架(Cu-MOF)材料。Cu-MOF与交联聚乙烯醇(CL-PVA)复合后经X-2R活性染料染色处理，得到染色膜CL-PVA@Cu-MOF-15-Y，对其结构、形貌、尺寸稳定性和质子导电率进行表征。试验结果显示，当染色浓度为10%时，膜样品在相对湿度90%和80 ℃条件下的质子电导率最高为3. 7×10-2 S/cm，质子传输以Vehicle机制为主导；膜样品各项性能均有不同程度的提升，拉伸强度和断裂伸长率分别为24. 2 MPa和230. 4%，吸水率和溶胀率分别为120. 6%和68. 2%。 |
| 英文摘要: |
| A novel copper based metal organic framework (Cu MOF) material was constructed based on sulfonic acid imidazolium ion pairs to modify ligands. Cu-MOF was compounded with crosslinked polyvinyl alcohol (CL-PVA) and dyed with X-2R reactive dyes to obtain the dyed film CL-PVA@Cu-MOF-15-Y. Its structure, morphology, dimensional stability and proton conductivity were characterized. The experimental results show that when the dyeing concentration is 10%, the highest proton conductivity of the membrane sample is 3. 7×10-2 S/cm at 90% relative humidity and 80 ℃, and the proton transmission is dominated by the Vehicle mechanism. All the properties of the membrane samples were improved to varying degrees, with tensile strength and elongation at break of 24. 2 MPa and 230. 4%, water absorption rate and swelling rate of 120. 6% and 68. 2%, respectively. |
