Polielektrolitske kapsule: ravnovesna porazdelitev vode in Donannovo ravnovesje ionov : doktorska disertacija
Haložan, David
Po metodi LbL (Layer-by-Layer) smo izdelali polielektrolitske kapsule z izmenično adsorbcijo polielektrolitov poli(allilamin hidroklorida) in natrijevega poli(stiren sulfonata) na polistirenske delce ...s polmerom ▫$10,25 \mu m$▫, ki smo jih nato odstranili s tetrahidrofuranom ali dimetilformamidom. Izvedli smo nov izvirni postopek ujetja polianionskih molekul poli(akrilne kisline) v notranjo raztopino teh polielektrolitskih kapsul. Metoda temelji na spremembi pozornosti stene kapsul, ki jo dosežemo z izpostavljanjem kapsul bazičnemu pH 11,4. Določili smo količino ujetega polianiona in odzivnosti polielektrolitskih kapsul na spremembe pH in spremembe koncentracije NaCl v zunanji raztopini. Meritve na populaciji kapsul smo izvedli s spektrofotometričnimi metodami. Meritve na posameznih kapsulah smo izvedli s konfokalnim laserskim vrstičnim mikroskopom. Fluorescenčni signal smo zajeli od fluorescentnih označevalcev, ki so pripeti na ujet polianion. Meritve smo opisali s preprostim matematičnim modelom Donnanovega ravnovesja malih ionov preko selektivno prepustne stene kapsule. Iz primerjave izmerjenih podatkov in napovedi modela ugotavljamo, da se ta sistem vede kot Donnanov sistem. Nakažemo tudi možnosti uporabe tega sistema kot senzorja pH in senzorja soli.
