摘　　要：以共轭亚油酸钠(SCL)修饰Fe_(3)O_(4)纳米颗粒制备SCL@Fe_(3)O_(4)纳米颗粒,并以其促进甘油-水体系发泡;利用光学接触角仪、表面张力仪和光学显微镜表征SCL@Fe_(3)O_(4)纳米颗粒的润湿性、气/液表面吸附和泡沫性能。结果表明,SCL@Fe_(3)O_(4)纳米颗粒具有合适的润湿性,吸附在气/液表面可以有效降低甘油-水体系的表面张力,从而改善其泡沫性能;水含量降低和颗粒浓度增加有利于减缓泡沫排液,当水含量为20%,SCL@Fe_(3)O_(4)纳米颗粒浓度为3%~5%时,泡沫性能最好。The surface of Fe_(3)O_(4)nanoparticles with sodium conjugated linoleate(SCL)to prepare SCL@Fe_(3)O_(4)nanoparticles,promoting non-aqueous foam of glycerol-water mixtures.Wettability,adsorption on the air/liquid surface and foamability of glycerol-water mixtures promoted by SCL@Fe_(3)O_(4)nanoparticles are determined by optical contact angle meter,surface tensiometer and optical microscope.Results indicate that SCL@Fe_(3)O_(4)nanoparticles show suitable wettability,resulting in effective reduction of the surface tension of glycerol-water mixtures by absorbing at the air/liquid surface,and thus improving foamability of the mixtures.Drainage of foam is reduced by decreasing water contents or increasing particle concentrations of SCL@Fe_(3)O_(4)nanoparticles,and best foamability is corresponding to the 20%water content and the particle concentration from 3%to 5%.
