Ethyl cellulose hydrophilic po'o le hydrophobic

Ethyl cellulose o se polymer synthetic lea e masani ona faʻaaogaina i pisinisi eseese, e aofia ai vailaʻau, meaʻai, ma tausiga a le tagata lava ia. E lauiloa mo ana mea e sili ona lelei e fai ata tifaga, maualuga le fetaui ma isi mea, ma lelei le tetee atu i vailaʻau ma mea tau le siosiomaga. O se tasi o mea taua o le ethyl cellulose o lona hydrophobicity, o se fuataga o lona vavalalata mo le vai.

Hydrophobicity o se meatotino o se mea e faʻamatalaina lona uiga e faʻafefe ai mole mole vai. I le tulaga lautele, o mea hydrophobic e le mafai ona solu pe le lelei ona solu i le vai ma e masani ona faʻafesoʻotaʻi ma isi molelaʻau hydrophobic. Ole Hydrophobicity e masani ona fa'aalia i le iai o vaega e le polar po'o le maualalo-polarity vaega i le fausaga mole, pei o filifili hydrocarbon po'o mama manogi.

Ethyl cellulose ua manatu o se polymer hydrophobic ona o le i ai o vaega ethyl i lona fausaga mole. O vaega o le ethyl e le polar ma le hydrophobic, ma o latou i ai e faʻateleina ai le hydrophobicity atoa o le polymer. E le gata i lea, o le ethyl cellulose o loʻo i ai se tikeri maualalo o le suia o vaega o le ethyl, lea e fesoasoani atili i lona uiga hydrophobic.

Ae ui i lea, o le hydrophobicity o le ethyl cellulose e mafai ona suia e ala i le suia o le tikeri o le suitulaga poʻo le faʻaopoopoina o vaega hydrophilic i le fausaga polymer. Mo se faʻataʻitaʻiga, o le faʻaofiina o vaega hydrophilic e pei o le hydroxyl poʻo le carboxyl vaega e mafai ona faʻateleina le hydrophilicity o le polymer ma faʻaleleia lona solubility i le vai. E mafai foi ona faateleina le tikeri o le suitulaga e faateleina ai le numera o vaega hydrophilic ma faaleleia ai le hydrophilicity o le polymer.

E ui lava i lona hydrophobicity, o le ethyl cellulose o loʻo manatu pea o se mea aoga mo faʻaoga eseese, aemaise lava ile fale gaosi oloa. O lona uiga o le hydrophobic e avea ai ma mea sili ona lelei mo le tu'uina atu o vaila'au, aua e mafai ona taofia ai le tu'uina atu o le susu po'o isi mea hydrophilic i totonu o le vaila'au. E mafai ona fesoasoani lenei mea e puipuia ai le mautu ma le aoga o le vailaʻau mo se taimi umi.

I se aotelega, o le ethyl cellulose o se polymer hydrophobic ona o le i ai o vaega ethyl nonpolar i lona fausaga mole. Ae ui i lea, o lona hydrophobicity e mafai ona suia e ala i le suia o le tikeri o le suitulaga poʻo le faʻaopoopoina o vaega hydrophilic i le fausaga polymer. E ui lava i lona uiga hydrophobic, o le ethyl cellulose o loʻo avea pea ma mea aoga mo faʻaoga eseese, aemaise lava ile fale gaosi oloa.
