Tej zaum qhov no yog kev txhawj xeeb ntawm ntau qhov hnyav rov qab tshuab tshuab. Hauv kev nkag siab qhov teeb meem no, cia peb xub nkag siab tias cov tshuaj hnyav sib xyaw yog dab tsi.
Cov tshuaj hnyav sib xyaw tsis yog qhov yooj yim nruab nrab ntawm qhov ua tau zoo ntawm ob lossis ntau dua cov kuab tshuaj. Hauv qee cov kuab tshuaj/cov tshuaj polymer zoo, cov kuab tshuaj tsis zoo (lossis tsis yog cov kuab tshuaj) tau maj mam ntxiv. Zoo, thiab tom qab ntawd tsis muaj zog; txawm tias qhov sib xyaw ntawm ob yam uas tsis yog cov kuab tshuaj tuaj yeem qhia tus cwj pwm ntawm cov kuab tshuaj zoo, uas yog hu ua cosolvent; tab sis kuj tseem muaj qhov xwm txheej uas ob lub kuab tshuaj dhau los ua cov kuab tshuaj tom qab sib xyaw. Txoj hauv kev no, qhov ua tau zoo ntawm cov kuab tshuaj sib xyaw tsis tuaj yeem txiav tawm ncaj qha los ntawm kev ua haujlwm ntawm cov tshuaj sib xyaw ua ke ob yam. Qhov xwm txheej ntawm cov kuab tshuaj sib tov yog nyuab dua. Nws cov khoom ua haujlwm tau zoo, cov khoom tsis zoo thiab tshem tawm cov ntim ntim, kev cuam tshuam ntawm ob lub kuab tshuaj hnyav, sib koom ua ke ntawm cov tshuaj hnyav, sib sau ua ke ntawm cov polymers hauv kev daws teeb meem, thiab cuam tshuam ntawm cov polymers ntawm qee yam khoom sib txawv xws li qhov tshwj xeeb adsorption ntawm cov kuab tshuaj muaj feem cuam tshuam. Lub dielectric tas li ntawm cov kuab tshuaj tuaj yeem cuam tshuam ncaj qha rau qhov kev sib tov ntawm cov tshuaj. Kev hloov pauv ntawm cov dej ua rau muaj kev hloov pauv hauv lub xeev thermodynamic, txheej txheem kinetic, thiab thermodynamic thiab kinetic sib npaug ntawm cov solute. Nyob rau tib lub sijhawm, qhov hnyav nruab nrab hloov pauv, kev sib cuam tshuam ntawm cov khoom hnyav, thiab kev sib cuam tshuam ntawm cov khoom hnyav thiab hnyav kuj hloov. Yog li ntawd, kev hloov pauv hauv qhov hnyav ib puag ncig yuav hloov pauv lub xeev cov khoom.
