两亲分子或表面活性剂在低浓度时以单分子状态分散于水中,当浓度增加到一定范围时,急速地聚集形成分子或离子的缔合体称为胶束(Micelle)。胶束属于胶体分散系,其分散系为大于1nm,小于0.5um,一般在5至50-100 nm范围内。分子结构中既有亲油部分也有亲水部分的两亲分子能够自发缔合成胶束,这些胶束由两亲分子的亲油部分缠绕构成内核,亲水部分则环绕在外构成外壳。这样的胶束结构
Amphiphilic molecules or surfactants are dispersed in water at low concentrations in a single molecule. When the concentration increases to a certain extent, the aggregates that rapidly accumulate to form molecules or ions are called micelles. Micelles belong to colloidal dispersion, the dispersion is more than 1nm, less than 0.5um, usually in the range of 5 to 50-100 nm. The amphiphilic molecules in both the lipophilic part and the hydrophilic part in the molecular structure spontaneously associate into micelles. These micelles are entangled with the lipophilic part of the amphiphilic molecule to form the core, while the hydrophilic part surrounds the outer shell. Such a micellar structure
