The hydrophobic monomers such as glycidyl octyl dimethylammonium chloride, glycidyl dodecyl dimethylammonium chloride, glycidyl tetradecyl dimethylammonium chloride was applied to the hydrophobic modification of two kinds of sodium cellulose sulfate in isopropyl alcohol under 65℃.The success of synthesis of a kind of novel amphoteric surfactant by FT-IR and NMR. 3. By the measuring surface tension of all kinds of amphoteric polymeric surfactants based on cellulose, the critic micelle concentration was obtained such as 0.4wt%、0.3wt%、0.25wt% and corresponding surface tension was about 30mN/m

通过动态接触角测量仪确定了各种纤维素表面活性剂的表面张力和临界胶束浓度，结果表明该类表面活性剂可与小分子表面活性剂的降低表面张力的能力相媲美，最低可达28.41 mN/m，随着疏水基中碳链的增长，降低表面张力的能力下降，而临界胶束浓度从0.4wt%相应降低0.25wt%；应用环境扫描电镜确定其不同浓度胶束形态，结果表明在较低浓度下形成棒状单分子胶束，随着浓度的升高，单分子胶束逐渐聚集成树枝状胶束，进一步提高浓度，则聚集成网状结构；此外，采用了高级流变仪对其溶液的流变性质进行了研究，结果表明其溶液属于剪切变稀流体，是高分子溶液特有的性质。
