中文摘要:
      以4-羟基偶氮苯、1,2-二溴乙烷、PEG600为原料,合成直链型偶氮苯聚氧乙烯醚非离子表面活性剂(PEP-600)。通过红外光谱和核磁共振氢谱表征了其结构,并测试了其表面活性。结果表明,PEP-600临界胶束浓度(CMC)为4.99×10-3 mol/L,在CMC处表面张力为48.09 mN/m,饱和吸附量为2.48×10-3 mmol/m2,亲水亲油平衡值(HLB)为14.20。将PEP-600与0.1 g/L的十二烷基硫酸钠复配最大发泡比为12,泡沫半衰期为220 s,直链型分子结构的PEP-600在泡沫液膜表面排列紧密,具有优异的起泡性能,可用作泡沫染整稳泡剂。
英文摘要:
      A linear-type azobenzenepolyoxyethylene ether nonionic surfactant (PEP-600) was synthesized by p-benzeneazophenol, 1,2-dibromoethane and polyethylene glycol (PEG600), used as a foam stabilizer, to reversibly photo-control foam stability. PEP-600 was characterized by FT-IR spectra and 1H-NMR spec-trum. Besides, its surface activity and foam properties were analyzed. The results showed that the critical micelle concentration (CMC) of PEP-600 was 4.99×10-3 mol/L and the surface tension was 48.09 mN/m at this concentration. The surface excess and HLB value of PEP-600 were 2.48×10-3 mmol/m2 and 14.20, respectively. Meanwhile, the foaming ratio of PEP-600 was about 12 and foam half-life was 220 s with sodium dodecyl sulfate (0.1 g·L-1), meaning that PEP-600 owned the excellent foaming property, which was attributed to the tight arrangement at the surface of foam film. PEP-600 had the potential to apply in foam dyeing as a foam stabilizer.
