摘　　要：添加适当的分散荆，考察纳米石墨在极性介质中的分散稳定性。通过粒径大小，Zeta电位以及吸光度等测试，分析分散剂及pH值对纳米石墨的分散稳定性效果的影响。结果表明，在pH值为10～11时，体系的Zeta电位绝对值最大，此时体系最稳定。羟甲基纤维素钠作为分散剂的分散效果最好。The dispersion of nano-graphite with proper dispersant in polarity medium was researched mainly. The influence of dispersants and pH on the dispersion stability was analyzed by testing particle size, zeta potential and absorbency, etc. The results showed that the absolute Zeta values of systems were maximal within pH=10-11. So the system was the most steady. The CMC was the best dispersant.
