Qhov sib txawv ntawm qhov yooj yim thiab nyuaj coacervation yog qhov yooj yim coacervation, tsuas yog ib hom polymer yog siv los ua coacervate, whereas, nyob rau hauv complex coacervation, ob los yog ntau tshaj polymers yog siv los ua lub coacervate.
Coacervation yog tsim los ntawm kev sib xyaw ntawm macromolecules xws li hluavtaws polymers, proteins, lossis nucleic acids thiab theem aqueous. Qhov sib tov no ua los ntawm cov kua-kua theem sib cais. Nws ua rau cov theem ntom ntom uas muaj nyob rau hauv cov thermodynamic sib npaug nrog rau theem dilute. Qhov sib tov no hu ua coacervate. Ntxiv mus, dispersed droplets ntawm qhov ntom ntom kuj hu ua coacervates.
Peb tuaj yeem hu ua coacervates li lyophilic colloids. Qhov no txhais tau tias theem ntom ntom qee cov thawj cov kuab tshuaj (piv txwv li dej) thiab feem ntau tsis vau rau cov khoom siv tawv; Hloov chaw, nws tseem yog cov khoom ua kua. Muaj ob hom kev coacervation yooj yim thiab complex uas siv tau los tsim ib coacervate.
Kev sib koom tes yooj yim yog dab tsi?
Yooj yim coacervation yog cov txheej txheem uas muaj kev siv tib lub polymer xws li gelatin lossis ethyl cellulose rau theem hloov. Yog li ntawd, coacervation yooj yim xav tau ib yam ntawm cov polymer, whereas complex coacervation siv ob los yog ntau hom polymers.
Raws li qee qhov kev tshawb fawb tshawb fawb, kev sib koom ua ke yooj yim tuaj yeem tshwm sim los ntawm qee cov ntsev. Feem ntau, cov theem sib cais hauv cov txheej txheem no yog coj los ntawm kev ntxiv ntsev, pH, lossis kub hloov pauv hauv cov tshuaj polymeric.
Kev sib koom ua ke yog dab tsi?
Complex coacervation yog cov txheej txheem zoo microencapsulation uas muaj txiaj ntsig zoo hauv kev lag luam tshuaj, zaub mov, kev ua liaj ua teb thiab textile. Cov txheej txheem no suav nrog kev sib cuam tshuam ntawm qhov sib txawv ntawm cov polyelectrolytes nyob rau hauv ib daim ntawv aqueous.
Cov txheej txheem coacervation nyuaj yog cov txheej txheem formaldehyde lossis glutaraldehyde-based. Cov txheej txheem no siv ob lub ntuj biodegradable polymers ntawm tus nqi sib txawv. Piv txwv li, peb tuaj yeem siv ib khub xws li alginate thiab gelatin. Feem ntau, gelatin yog siv los ua cationic polymer. Raws li anionic polymer, muaj ntau yam ntuj tsim thiab hluavtaws dej-soluble polymers uas peb tuaj yeem siv los cuam tshuam nrog gelatin los ua ib qho kev sib koom ua ke. Txawm li cas los xij, kev lag luam khoom noj feem ntau siv cov pos hniav Arabic nkaus xwb.
Dab tsi yog qhov sib txawv ntawm qhov yooj yim thiab nyuaj Coacervation?
Yooj yim coacervation yog cov txheej txheem uas muaj kev siv tib lub polymer xws li gelatin lossis ethyl cellulose rau theem hloov. Complex coacervation yog ib theem kua-kua sib cais tshwm sim nyob rau hauv cov kev daws teeb meem ntawm oppositely-them macromolecular hom, xws li cov proteins, polymers, thiab colloids. Qhov sib txawv ntawm qhov yooj yim thiab txoj kev coacervation yog qhov yooj yim coacervation, tsuas yog ib hom polymer yog siv los ua coacervate, whereas, nyob rau hauv complex coacervation, ob los yog ntau tshaj polymers yog siv los ua cov coacervate.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm qhov yooj yim thiab nyuaj coacervation hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Yooj yim vs Complex Coacervation
Coacervation yog tsim los ntawm kev sib xyaw ntawm macromolecules xws li hluavtaws polymers, proteins, lossis nucleic acids, thiab theem aqueous. Muaj ob hom kev txuag; lawv yog cov yooj yim thiab complex coacervation. Qhov sib txawv ntawm qhov yooj yim thiab nyuaj coacervation yog qhov yooj yim coacervation tsuas yog siv ib hom polymer los ua coacervate, qhov nyuaj coacervation siv ob lossis ntau dua polymers.
