Cov ntsiab lus tseem ceeb thiab qhov sib txawv ntawm cov roj hmab txhawb ntxiv thiab muab tub lim

Txawm hais tias polymer xws li cov roj hmab tuaj yeem ntub cov nplaim ntawm cov neeg ua kom muaj zog yog qhov tsim nyog ua ntej rau tus neeg sawv cev rov qab los ua lub luag haujlwm txhawb nqa. Txawm tias tus neeg sawv cev tiv thaiv kab mob tuaj yeem ntub lossis tsis yog nyob ntawm cov khoom ntawm cov pab pawg nquag nyob rau saum npoo. Tsuas yog thaum cov saum npoo nquag pab pawg ntawm tus neeg txhawb zog yog lipophilic nws tuaj yeem ua ntub dej los ntawm polymers xws li roj hmab. Ib yam li ntawd, thaum lub saum npoo active pawg ntawm polymers yog hydrophilic, nws yog tsis yooj yim sua kom hydrocarbon thiab ester polymers yuav tsum tau ntub. Txawm hais tias macroscopically lawv tuaj yeem sib xyaw rau hauv ib qho, kev sib tiv tauj hauv micro kuj tseem sib cais.
