Qhov kev ruaj ntseg ntawm micelles tuaj yeem xav txog feem ntau ntawm cov ntsuas kub thiab kinetic stability. Thermodynamic stability piav qhia txog yuav ua li cas lub kaw lus ua raws li micelles tsim thiab ncav cuag qhov sib npaug.

Puas micelles ruaj khov?

Ntawm cov polymer siab siab, micelles ruaj khov tshwj tsis yog lawv tau diluted hauv qab CMC. Tom qab ntawd cov micelles yuav disassemble thiab dawb chains rov pom nyob rau hauv cov tshuaj ntau thiab adsorbed ntawm huab cua-dej interface los yog aqueous-organic hnyav interface.

Puas micellar cov kev daws teeb meem puas ruaj khov?

Lub kaw lus yog tsim los ntawm tus kheej, thiab nws yog thermodynamically ruaj khov.

micelles stabilized li cas?

Qhov nrov tshaj plaws covalent crosslinking lub tswv yim suav nrog tsim ntawm covalent bonds / crosslinking nyob rau hauv tshwj xeeb domains ntawm micelle, xws li lub plhaub thiab core domains. Qhov no txhawb nqa qhov tsis muaj zog ntawm kev sib cuam tshuam hauv nruab nrog cev thiab yog li stabilizes micelles.

Dab tsi yog qhov tseem ceeb ntawm thermodynamics ntawm micellization?

Taw qhia. Raws li tau hais ua ntej, cov txheej txheem ntawm micellization yog ib qho ntawm cov yam ntxwv tseem ceeb ntawm cov tshuaj surfactantthiab yog li nws yog qhov tseem ceeb kom nkag siab txog nws cov txheej txheem (tus tsav tsheb rau kev tsim micelle). Qhov no yuav tsum tau tsom xam ntawm ob qho tib si kinetic thiab qhov sib npaug ntawm cov txheej txheem.
