水溶性共聚物SMA,SSMA与表面活性剂相互作用的荧光研究

Study on the Interaction of Copolymers with Surfactants by Flurorescent Probe

摘要: 利用荧光光谱配以通常的表面张力法，测定了水溶性苯乙烯－马来酸印共聚物（ＳＭＡ）和磺化苯乙烯－马来酸酐共聚物（ＳＳＭＡ）的表面活性，研究了其与表面活性剂十二烷基硫酸钠（ＳＤＳ）、十二烷基聚氧乙烯醚（ＤＥ＿９）之间的相互作用。结果表明，由于具有高表面活性的ＳＳＭＡ与ＳＤＳ、ＤＥ＿９之间存在着强的增效作用，添加０．１％ＳＳＭＡ就可大大提高表面活性剂的使用效果。ＳＭＡ与上述表面活性剂的复配增效作用比ＳＳＭＡ要弱。

Abstract: The combination of fluorescence spectroscopy and traditional surface tensionmethod are used to investigate the interaction of hydrosoluble copolymers SMA and SSMAwith surfactants SDS,DE_9.Results show great synergistic effects of SSMA-anionic mixturesystem,The surface activity can be increased greatly by adding only 0.1%of SSMA to anion-ic solution. The synergism of SMA with above surfactants is weaker than SSMA.
