研制了1-丁基-3-甲基咪唑氯和1- h -3-甲基咪唑氯二元离子液体（ILs），用于溶解壳聚糖和纤维素以及分散多壁碳纳米管（MWCNTs）。该混合浆料可用于制备壳聚糖/纤维素/MWCNT复合膜和纤维。采用傅里叶变换红外光谱、广角x射线衍射、热重分析、扫描电镜、拉伸测试和电导率测量来评估复合材料的结构和性能以及不同载荷下MWCNTs掺入的效果。表征结果表明，MWCNTs的掺入提高了复合材料的综合性能，MWCNTs的最佳负载为4 wt %。该方法是制备壳聚糖/纤维素/MWCNT复合膜和纤维的一种绿色可行的方法，将为制备类似材料提供有益的参考。©2012 Wiley期刊公司j:。变异较大。科学。, 2013年
Binary ionic liquids (ILs), 1-butyl-3-methylimidazolium chloride and 1-H-3-methylimidazolium chloride, were developed to dissolve chitosan and cellulose and disperse multiwalled carbon nanotubes (MWCNTs). The resulting mixed paste could be used to prepare chitosan/cellulose/MWCNT composite membranes and fibers. Fourier transform infrared spectroscopy, wide-angle X-ray diffraction, thermogravimetric analysis, scanning electron microscopy, tensile testing, and conductivity measurements were used to evaluate the structure and properties of the composite materials and the effect of the incorporation of MWCNTs at various loadings. The characterization results indicate that the incorporation of MWCNTs improved the comprehensive performances of the composite materials, and the best loading of MWCNTs was 4 wt %. This IL dissolution method is a green and feasible method for preparing chitosan/cellulose/MWCNT composite membranes and fibers and will provide beneficial references for the preparation of similar materials. © 2012 Wiley Periodicals, Inc.
