[交流] 制备聚酯（m-苯二胺）/还原氧化石墨烯水凝胶的过程以及它在吸附领域的应用已有1人参与

A Cu m phenylenediamine complex induced route to fabricate poly(m phenylenediamine)/reduced graphene oxide hydrogel and its adsorption application. Carbon 81 (2015) 748 - 757. 影响因子：6.16
摘要：Cu m phenylenediamine (Cu mPD) complex was ﬁrstly exploited to efﬁciently synthesize poly(m phenylenediamine)/reduced graphene oxide (PmPD/rGO) hydrogel. Cu mPD complex shows high gelation and redox reaction activity with GO, which is ascribed to the joint andmediation effect of Cu2+. The green and efﬁcient route realized highmonomer polymerization (>99%) and decreased hydrothermal reaction time (1 h) without additional polymerization process. Scanning electron microscopy, X ray diffraction, X ray photoelectron spectroscopy, Fourier transformed infrared spectroscopy, and Raman spectroscopy were conducted to characterize the morphology and structure of PmPD/rGO hydrogel. The macroscopic hydrogels exhibit high porosity, good mechanical strength, superior adsorption performance (with methylene blue adsorbance of 615mg g 1), and readily recycle properties.
中文翻译摘要：首次利用Cu-m-苯二胺（Cu-mPD）复合体高效的合成了聚酯（m-苯二胺）/还原氧化石墨烯水凝胶。Cu-mPD复合体具有高的凝胶化作用、与GO有高的氧化还原反应活性，这归因于Cu2+离子的交联和调停效应。这种环保高效的方法实现了高的单体聚合作用（＞99%），降低了水热反应时间（1h）而没有额外的聚合过程。用扫描电子显微镜、X-射线衍射、X射线光电子谱、傅里叶变换红外光谱学和拉曼光谱学表征pmPD/rGO水凝胶的形貌和结构。宏观上水凝胶具有高的孔隙率，好的机械性能，高的吸收性能（亚甲基蓝的吸附量是615mgg-1），以及好的循环性能。
