改性水滑石复合质子交换膜的制备及性能VIP专享

I壳聚糖/改性水滑石复合质子交换膜的制备及性能摘要：这里用来制备改性水滑石(Q-LDH)的方法是季铵化改性，在壳聚糖（CS）基体中混合剂量不一的改性水滑石制成了不同含量 Q-LDH 的 CS/改性水滑石复合质子交换膜。采用 IR 和 TG 分析改性水滑石的结构以及组成。对复合膜的断面形态，通过 SEM 来观测，同时采取措施测试出了复合膜的各种性质，比方说质子传导率、尺寸稳定性等等。测试完成后发现，在各项性能指标中，最为优越的一种指标是热稳定性。在加入改性水滑石以后，得到了显著提高的性能指标有质子传导率还有其力学性能，其他的性能指标没有变化。关键词：壳聚糖；改性水滑石；质子交换膜IIPreparation and properties of chitosan/modified hydrotalcite composite proton exchange membraneAbstract: The method of preparing modified hydrotalcite (Q-LDH) is quaternary ammonium modification. CS/modified hydrotalcite composite proton exchange membranes with different content of Q-LDH were prepared by mixing different doses of Modified Hydrotalcite in chitosan (CS) matrix. The structure and composition of the Modified Hydrotalcite were analyzed by IR and TG. The cross-sectional morphology of the composite film was observed by SEM. Meanwhile, various properties of the composite film, such as proton conductivity, dimensional stability and so on, were tested. After testing, it is found that thermal stability is one of the most superior performance indicators. After adding the modified hydrotalcite, the properties of the Modified Hydrotalcite have been significantly improved, including proton conductivity and mechanical properties, while the other properties have not changed..Key word：Chitosan; modified hydrotalcite; proton exchange membraneIII目录摘要...................................................................................................................................................I关键词.................................................................................
