摘　　要：以十二烷基缩水甘油醚为原料合成了疏水改性海藻酸钠(DGE-alginate),研究了DGE-alginate的表面活性及胶束性质。结果表明:DGE-alginate具有良好的表面活性,在水溶液中可以形成具有核-壳结构的胶束。DGE-alginate在水溶液中的临界胶束浓度为4.0mg/mL,粒径大约为1000 nm,Zeta电位为-63±1mV。Hydrophobically modified alginate DGE-alginate was obtained with sodium alginate and dodecyl glycidyl ether（DGE） as materials. The surface activity and particle size distribution of DGE-alginate was studied. The results showed that DGE-alginate could form core-shell micelles in aqueous solution, and the critical micelle concentration（CMC） was 4.0 mg/mL. The micelle diameter of DGE-alginate was about 1000 nm, and the Zeta potential was-63±1mV.
