Cov cuab yeej dielectric, raws li kev ntsuas ntawm lub peev xwm teb ntawm cov khoom nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb, yog ib qho tseem ceeb indispensable Performance index los ntsuam xyuas cov hluav taws xob khoom ntawm cov khoom. Los ntawm kev ntsuam xyuas dav thiab cov ncauj lus kom ntxaws, peb tuaj yeem nkag siab qhov kev ua tau zoo ntawm cov khoom siv nyob rau hauv qhov kev txiav txim ntawm hluav taws xob, suav nrog tab sis tsis txwv rau dielectric tas li, dielectric poob, rwb thaiv tsev lub zog thiab dielectric tawg voltage.
Dielectric tas li, qhov ntau ntawm lub cev ncaj qha qhia txog qib ntawm polarization ntawm cov khoom hauv hluav taws xob. Nws tus nqi yog lub hauv paus ncaj qha los ntsuas qhov hluav taws xob teb qhov muaj peev xwm ntawm cov khoom siv, thiab qhov loj dua tus nqi tas li, qhov tseem ceeb tshaj qhov tshwm sim ntawm cov khoom siv hauv qab qhov kev txiav txim ntawm hluav taws xob teb.
Dielectric poob yog hais txog lub zog poob ntawm cov khoom nyob rau hauv qhov kev txiav txim ntawm ib qho hluav taws xob teb, uas feem ntau yog xam los ntawm qhov poob yam. Qhov ntsuas no qhia txog qhov xwm txheej tshwj xeeb ntawm lub zog dissipation ntawm cov khoom hauv hluav taws xob.
Rwb thaiv tsev lub zog, qhov ntsuas no yog siv los ntsuas qhov siab tshaj plaws hluav taws xob teb lub zog uas cov khoom tuaj yeem tiv taus nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb, thiaj li txiav txim siab qhov rwb thaiv tsev ntawm cov khoom.
Dielectric breakdown voltage, uas sawv cev rau qhov voltage qhov pib ntawm cov khoom nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb tawg, los ntawm kev ntsuam xyuas qhov Performance index, peb yuav soj ntsuam cov khoom nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb breakdown resistance peev xwm.
Hauv kev sim dielectric zog, kev sim ntawm qhov kub qis muaj ntau yam zoo.
Ua ntej, nws tuaj yeem qhia meej meej cov txheej txheem ntawm kev cuam tshuam ntawm qhov kub thiab txias ntawm dielectric zog, los ntawm kev sim ntawm qhov sib txawv ntawm qhov kub thiab txias, peb tuaj yeem soj ntsuam qhov sib txawv ntawm cov khoom siv nrog qhov kub thiab txias, uas yog qhov tseem ceeb rau peb kom nkag siab txog kev ua tau zoo ntawm cov ntaub ntawv nyob rau hauv cov xwm txheej tshwj xeeb lossis huab cua. .
Qhov thib ob, kev ntsuas kub qis pab txhim kho qhov tseeb thiab kev ntseeg siab ntawm qhov kev sim, txo qhov cuam tshuam ntawm cov suab nrov thermal thiab lwm yam cuam tshuam uas yuav cuam tshuam los ntawm qhov kub thiab txias ib puag ncig, yog li txhim kho qhov tseeb ntawm cov ntaub ntawv xeem. Tsis tas li ntawd, qhov ntsuas kub tsis tshua muaj peev xwm kuj simulate qhov kub thiab txias hloov hauv qhov chaw siv tiag tiag, kom cov txiaj ntsig kev ntsuas tau ze rau qhov tseeb ntawm daim ntawv thov scenario.
Thaum kawg, kev ntsuas kub qis pab nthuav dav qhov kev ntsuas kom npog ntau qhov kev ua haujlwm kub thiab zaus, muab cov ntaub ntawv nthuav dav ntxiv rau kev siv cov khoom siv.
Nyob rau hauv cov nqe lus ntawm daim ntawv thov, tsis tshua muaj kub dielectric khoom kuaj yog haum rau ntau yam ntaub ntawv, xws li cov ntaub ntawv ceramic, nyias zaj duab xis cov ntaub ntawv, khoom electrolytes thiab multi-functional composite cov ntaub ntawv. Piv txwv li, nyob rau hauv cov ntaub ntawv ceramic, qhov kub thiab txias ib puag ncig tuaj yeem ua rau muaj kev hloov pauv loj hauv lawv cov khoom dielectric, yog li kev ntsuas kub qis yog qhov tseem ceeb kom nkag siab txog lawv cov kev ua tau zoo. Rau cov ntaub ntawv nyias nyias, uas tau siv dav hauv microelectronics thiab semiconductor teb, lawv cov khoom siv hluav taws xob muaj kev cuam tshuam ncaj qha rau cov cuab yeej cuab yeej, thiab kev ntsuas kub tsawg pab qhia lawv tus cwj pwm dielectric ntawm qhov kub thiab txias. Nyob rau hauv cov nqe lus ntawm cov khoom electrolytes, ntsuas kub tsis tshua muaj pab kom nkag siab txog lawv cov ion conduction thiab dielectric zog ntawm qhov kub thiab txias, thiab muab kev taw qhia rau kev txhim kho kev ua tau zoo ntawm cov khoom siv hluav taws xob tshiab xws li cov roj teeb hauv lub xeev thiab cov supercapacitors. Rau multifunctional composites, kev ntsuas kub tsis tshua muaj peev xwm ntsuas lawv cov kev ua tau zoo hauv cov cheeb tsam nyuaj thiab muab kev txhawb nqa rau lawv cov kev nce qib hauv kev siv tswv yim.
