报道了聚电解质复合物的一种新的溶剂体系———离子表面活性剂剂的水溶液 ,研究了表面活性的用量及结构、温度、外加小分子电解质对复合物溶解性的影响 ,初步探讨了溶解机理 ,通过扫描电镜观察了复合物溶解后在溶液中的形态 .研究表明 ,当复合物与离子表面活性剂定量结合到一定程度时 ,就会使复合物发生溶解 .表面活性剂碳链长度的增加、温度的提高均会对复合物的溶解有不同程度的促进 .加入少量的无机电解质如氯化钠 ,会促进复合物的溶解 ,若氯化钠加入量过多 ,反而不利于复合物的溶解 .复合物的溶解机理被认为是表面活性剂的解离作用和疏水作用二者的协同 .
Reported a new solvent system of polyelectrolyte complex --- ionic surfactant aqueous solution, studied the amount and structure of surface activity, temperature, plus a small molecule electrolyte on the solubility of the complex, initially discussed The mechanism of dissolution and the morphology of the complex dissolved in solution were observed by scanning electron microscopy.The results showed that when the complex and ionic surfactant were quantitatively bound to a certain extent, the complex would dissolve.The carbon chain length , The increase of temperature will promote the dissolution of the composites to some extent.Adding a small amount of inorganic electrolyte such as sodium chloride will promote the dissolution of the complex.If too much sodium chloride is added, The dissolution mechanism of the complex is believed to be a synergy of both the dissociation and hydrophobic effects of the surfactant.
