聚氧乙烯醚型表面活性剂的合成及表面性质
Surface and Interfacial Properties of Polyoxyethylene Ether-type Surfactants
摘要
Abstract
A series of poly nonylphenol polyoxyethylene ether nonionic surfactants with different polymeriza-tion degerees was synthesized with nonyl phenol and formaldehyde. The structures were characterized by infra-red spectroscopy and nuclear magnetic resonance. Moreover, the surface properties were evaluated using the surface tension method. It is found that critical micelle concentration(cmc) of monomer, dimer and trimer in-cease with increasing of the number of hydrophilic group epoxyethane(EO) of the surfactants. In the case of the same number of EO, the cmc of surfactants were significantly reduce with the increase of the degree of polymerization. Although dimer and trimer show good surface properties, the surface property of trimer is more excellent than dimer. Moreover, dimer and trimer show more excellent adsorption and dispersion performance because the arrangments of them on the air/ water boundary are significantly more compacted than dimer.关键词
