高聚物O-乙基-O-(2-羟乙基)纤维素(英文缩写为EHEC)与表面活性剂之间相互作用的研究,国外已有报道,但对于其作用机理并不十分清楚.本文试图在已有工作基础上,采用不同于国外的实验方法及手段,对表面活性剂与EHEC之间的相互作用做更深入的研究.本文利用单分子膜技术,测定了十二烷基硫酸钠(SDS),十六烷基三甲基溴化铵(CTAB),以及辛基苯基聚氧乙烯醚(TritonX-100)三类具有不同电荷的表面活性剂在高聚物EHEC的水溶液表面上成膜的π-A曲线,结果表明:在我们的实验条件下,高聚物EHEC都能不同程度地降低三类表面活性剂的表面张力,其中以CTAB的表面张力下降的最多. The research on the interaction between polymer O-ethyl-O- (2-hydroxyethyl) cellulose (abbreviated as EHEC) and surfactant has been reported in foreign countries, but its mechanism of action is not very clear In this paper, based on the existing work, this paper attempts to study the interaction between surfactant and EHEC by using different experimental methods and methods from foreign countries.In this paper, monolayer technique was used to determine the dodecyl Three kinds of surfactants having different charges, such as sodium sulfate (SDS), cetyltrimethylammonium bromide (CTAB) and octylphenyl polyoxyethylene ether (TritonX-100) Π-A curve of the film surface, the results show that: under our experimental conditions, the polymer EHEC can reduce the surface tension of the three types of surfactants to varying degrees, with the CTAB surface tension dropped the most.
