摘要
反气相色谱优势在于该技术可以在一个宽广的温度范围内对材料的表面性质进行表征,具有简便、快速、准确的特点。本文采用XRD、红外光谱仪、气相色谱仪对碳纳米管、碳黑及石墨烯三种材料的成分、结构进行表征,借助色谱工作站对数据进行采集;通过色谱工作站采集的数据运用已有的知识计算碳纳米管、碳黑及石墨烯三种材料的色散自由能等相关参数。结果表明:炭黑、碳纳米管和石墨烯的保留时间均随探针分子的横截面积增加而增加;碳纳米管的色散自由能最大,其次是石墨烯,最小的是炭黑;三种物质的色散自由能均随着比表面积的增加而增加,两者的线性相关因素为0.5902;三种物质的表面活性中,色散自由能起着主要的作用。
Inverse gas chromatography the advantage of the technology can be in a wide temperature range of surface properties of materials were characterized with characteristics of simple, rapid and accurate. In this paper, the composition and structure of three carbon nano-tubes, carbon black and graphene were characterized by XRD, infrared spectrometer and gas chromatograph. The data were collected by chromatographic workstation; The dispersion free energy and surface free energy polar parameters of three kinds of carbon nano-tubes, carbon black and graphene are calculated by using the data collected from the chromatographic workstation. The result shows: The retention time of carbon black, carbon nano-tubes and graphene increases with the increase of the cross sectional area of the probe molecules; Carbon nano-tubes have the largest dispersion free energy, followed by graphene, and the smallest is carbon black; The dispersive free energy of three kinds of materials increases with the increase of specific surface area, and the linear correlation factor is 0.5902. The dispersion free energy plays a major role in the surface activity of three kinds of materials.
