Txo qhov nro saum npoo
Surfactant molecules yog txheej txheem ntawm ob theem, ua rau qhov chaw ntawm ob theem sib npaug rau kev hloov mus rau sab hauv ntawm cov molecules, yog li txo qhov nro ntawm qhov chaw. Piv txwv li, ntawm cov kua roj interface, surfactants txo qhov nro ntawm dej los ntawm adsorption.
Daim ntawv aggregates
Nyob rau hauv lub bulk aqueous theem, surfactants yuav tsim aggregates, xws li micelles. Tus Tsov tus tw hydrophobic tsim cov tub ntxhais ntawm cov aggregate, thaum lub taub hau hydrophilic los rau hauv kev sib cuag nrog cov kua nyob ib puag ncig. Cov duab ntawm cov aggregate nyob ntawm cov qauv tshuaj ntawm cov surfactant, uas yog qhov sib npaug ntawm lub taub hau hydrophilic thiab hydrophobic tail, uas yog ntsuas los ntawm hydrophilic oleophilic tshuav nyiaj li cas (HLB). Ntxiv nrog rau micelles, lwm hom kev sib sau xws li kheej kheej lossis cylindrical micelles, lipid bilayers, thiab lwm yam kuj tuaj yeem tsim.
