Also known as colloids

A colloid is a mixture in which one substance, consisting of microscopically dispersed insoluble particles, is suspended throughout another substance. Some definitions specify that the particles must be dispersed in a liquid, while others extend the definition to include substances like aerosols and gels. The term colloidal suspension refers unambiguously to the overall mixture (although a narrower sense of the word suspension is distinguished from colloids by larger particle size). A colloid has a dispersed phase (the suspended particles) and a continuous phase (the medium of suspension). thu

AI overview

A colloid is a mixture where tiny, insoluble particles are suspended throughout another substance—like particles floating in a liquid, gas, or gel. Colloids matter because they're common in everyday materials (milk, fog, and paint are all examples) and understanding their structure helps explain how these mixtures behave and function.

在化學中,膠體(英語:Colloid)又稱膠狀分散體(colloidal dispersion)是一種,是的,在膠體中含有兩種不同相態的物質,被分散的物质称为分散相(或:分散质),另一种连续分布的物质称为分散介质(或:分散剂、分散媒)。分散的一部分可以是由许多原子或分子(103-106个)組成的有界面的粒子,大小(直径)介於1nm到100nm之間,也可以是没有相界面的大分子或胶束,前者称为溶胶,后者称为高分子溶液或缔合胶体。
