Ethyl cellulose hydrophilic los yog hydrophobic

Ethyl cellulose yog ib qho hluavtaws polymer uas tau siv dav hauv ntau lub lag luam, suav nrog tshuaj, khoom noj, thiab kev saib xyuas tus kheej. Nws yog lub npe hu rau nws zoo heev zaj duab xis-forming zog, siab compatibility nrog rau lwm yam ntaub ntawv, thiab zoo kuj rau tshuaj thiab ib puag ncig yam. Ib qho ntawm cov khoom tseem ceeb ntawm ethyl cellulose yog nws cov hydrophobicity, uas yog ib qho kev ntsuas ntawm nws cov affinity rau dej.

Hydrophobicity yog ib yam khoom ntawm ib yam khoom uas piav txog nws txoj kev nyiam ua rau cov dej molecules. Feem ntau, cov tshuaj hydrophobic yog insoluble los yog tsis zoo soluble nyob rau hauv dej thiab nyiam mus koom nrog lwm cov hydrophobic molecules. Hydrophobicity feem ntau tshwm sim los ntawm qhov muaj cov pawg tsis muaj polarity los yog tsawg-polarity nyob rau hauv cov qauv molecular, xws li hydrocarbon chains los yog aromatic rings.

Ethyl cellulose yog suav tias yog hydrophobic polymer vim muaj cov ethyl pawg hauv nws cov qauv molecular. Cov pab pawg ethyl yog nonpolar thiab hydrophobic, thiab lawv lub xub ntiag ua rau kom tag nrho hydrophobicity ntawm polymer. Tsis tas li ntawd, ethyl cellulose muaj qhov tsis tshua muaj kev hloov pauv ntawm ethyl pawg, uas ntxiv rau nws tus cwj pwm hydrophobic.

Txawm li cas los xij, hydrophobicity ntawm ethyl cellulose tuaj yeem hloov kho los ntawm kev hloov pauv qib lossis los ntawm kev ntxiv cov pab pawg hydrophilic rau cov qauv polymer. Piv txwv li, kev qhia txog cov pab pawg hydrophilic xws li hydroxyl lossis carboxyl pawg tuaj yeem ua rau kom cov hydrophilicity ntawm polymer thiab txhim kho nws cov solubility hauv dej. Cov degree ntawm kev hloov pauv kuj tuaj yeem nce ntxiv kom muaj cov pab pawg hydrophilic thiab txhim kho cov hydrophilicity ntawm polymer.

Txawm hais tias nws hydrophobicity, ethyl cellulose tseem suav tias yog cov khoom siv tau zoo rau ntau yam kev siv, tshwj xeeb hauv kev lag luam tshuaj. Nws tus cwj pwm hydrophobic ua rau nws yog ib qho khoom thaiv zoo heev rau kev xa cov tshuaj, vim nws tuaj yeem tiv thaiv kev nkag mus ntawm cov dej noo lossis lwm yam tshuaj hydrophilic rau hauv daim ntawv ntau npaum. Qhov no tuaj yeem pab tiv thaiv kev ruaj ntseg thiab kev ua tau zoo ntawm cov tshuaj nyob rau lub sijhawm ntev dua.

Hauv cov ntsiab lus, ethyl cellulose yog hydrophobic polymer vim muaj cov pawg tsis muaj polar ethyl hauv nws cov qauv molecular. Txawm li cas los xij, nws cov hydrophobicity tuaj yeem hloov kho los ntawm kev hloov cov qib ntawm kev hloov pauv lossis ntxiv pawg hydrophilic rau cov qauv polymer. Txawm hais tias nws tus cwj pwm hydrophobic, ethyl cellulose tseem yog cov khoom siv rau ntau yam kev siv, tshwj xeeb hauv kev lag luam tshuaj.
