Cov khoom siv kho tshuab ntawm cov txheej membrane raug cuam tshuam los ntawm qhov adhesion, kev ntxhov siab, kev sib sau ua ke, thiab lwm yam. Los ntawm kev sib raug zoo ntawm cov khoom siv txheej membrane thiab cov txheej txheem, nws tuaj yeem pom tias yog tias peb xav txhim kho lub zog kho tshuab ntawm cov txheej membrane, peb yuav tsum tsom mus rau cov txheej txheem hauv qab no:
(1) theem nqus tsev. Lub nqus tsev ntawm kev ua tau zoo ntawm zaj duab xis yog qhov pom tseeb heev. Feem ntau ntawm cov ntsuas kev ua tau zoo ntawm cov txheej zaj duab xis yog nyob ntawm theem nqus tsev. Feem ntau, thaum qib nqus tsev nce ntxiv, qhov ceev ntawm zaj duab xis nce ntxiv, qhov ruaj khov nce ntxiv, cov qauv zaj duab xis zoo dua, cov tshuaj lom neeg ua rau ntshiab, tab sis tib lub sijhawm kev ntxhov siab kuj nce ntxiv.
(2) Tus nqi tso tawm. Txhim kho tus nqi tso tawm tsis yog tsuas yog siv tau los txhim kho tus nqi evaporation, uas yog, ua kom qhov kub ntawm qhov chaw evaporation nce ntxiv, kuj tseem siv tau los ua kom thaj chaw evaporation nce ntxiv, tab sis kev siv qhov chaw evaporation los ua kom qhov kub ntawm txoj hauv kev muaj nws qhov tsis zoo: ua rau txheej membrane ntxhov siab dhau; cov roj ua yeeb yaj kiab yooj yim rau decompose. Yog li qee zaum nce thaj chaw evaporation dua li txhim kho qhov kub ntawm qhov chaw evaporation zoo dua.
(3) qhov kub ntawm lub substrate. Qhov kub ntawm lub substrate ua rau cov roj molecule seem nyob rau saum npoo ntawm lub substrate adsorption kom tsis txhob muaj, ua rau lub substrate thiab lub zog khi ntawm cov molecule uas tau tso rau hauv lub substrate: tib lub sijhawm yuav txhawb kev hloov pauv ntawm kev nqus lub cev mus rau kev nqus tshuaj, txhim kho kev sib cuam tshuam ntawm cov molecule, kom cov qauv txheej membrane nruj. Piv txwv li, Mg, membrane, cua sov rau 250 ~ 300 ℃ tuaj yeem txo qhov kev ntxhov siab sab hauv, txhim kho qhov ceev ntawm kev sib sau ua ke, ua rau lub zog ntawm txheej membrane nyuaj dua: cua sov rau 120 ~ 150 ℃ npaj Zr03-Si02, ntau txheej membrane, nws lub zog kho tshuab nce ntau, tab sis qhov kub ntawm lub substrate siab dhau yuav ua rau txheej membrane puas tsuaj.
(4) Kev foob pob Ion. Kev foob pob Ion muaj feem cuam tshuam rau kev tsim cov nplaim sib xyaw ua ke, qhov roughness ntawm qhov chaw, oxidation thiab aggregation density. Kev foob pob ua ntej txheej tuaj yeem ntxuav qhov chaw thiab ua rau muaj kev nplaum ntxiv; kev foob pob tom qab txheej tuaj yeem txhim kho qhov ceev ntawm cov zaj duab xis txheej, thiab lwm yam, yog li ua rau lub zog thiab qhov nyuaj ntawm cov khoom siv kho tshuab nce ntxiv.
(5) Kev ntxuav cov khoom siv hauv pem teb. Txoj kev ntxuav cov khoom siv hauv pem teb tsis tsim nyog lossis tsis huv, cov khoom seem lossis cov tshuaj ntxuav hauv cov khoom siv hauv pem teb, tom qab ntawd ua rau muaj kuab paug tshiab, hauv cov txheej txheem ntawm cov xwm txheej sib txawv thiab kev nplaum, cuam tshuam rau thawj txheej ntawm cov yam ntxwv ntawm cov qauv thiab qhov tuab ntawm lub teeb, tab sis kuj ua rau txheej zaj duab xis yooj yim tawm ntawm cov khoom siv hauv pem teb, yog li hloov cov yam ntxwv ntawm cov txheej zaj duab xis.
