Txij li kev siv cov txheej txheem polymer ua ntej los npaj cov khoom siv ua tau zoo tshaj plaws tau thov ntau dua 30 xyoo dhau los, SiOC macroporous ceramics tau siv dav hauv qhov ntsuas kub siab thiab MEMS rau qhov kub thiab txias ib puag ncig vim lawv qhov kub tsis kam tiv thaiv, tshav kub, hluav taws xob qhov hnyav, thiab kev tiv thaiv corrosion. , Lithium roj teeb cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob ci ci thiab lwm yam. Nrog rau kev thov maj mam ntawm SiOC macroporous ceramics hauv thaj tsam ntawm kev tiv thaiv cua sov kub, nws cov khoom cua sov, xws li thermal stability thiab muaj peev xwm hloov cua sov, yuav yog qhov teeb meem tseem ceeb. Raws li qhov teeb tsa no, muaj qhov xav tau nrawm los kawm txog kev ua haujlwm rwb thaiv tsev cua sov ntawm SiOC macroporous ceramics thiab txoj kev xav uas pab nws txoj kev ua kom zoo dua qub.
Tsis ntev los no, cov kws tshawb fawb los ntawm Kev Tshawb Fawb Txog Kev Tshawb Fawb thiab Kev Tshawb Fawb Kev Tshawb Fawb ntawm Lub Koom Haum ntawm Engineering Thermophysics ntawm Suav Academy ntawm Kev Tshawb Fawb tau kawm txog kev hloov pauv kub ntawm SiOC macroporous ceramics npaj los ntawm cov txheej txheem polymer ua ntej. Qhov pom kev ua kom sov ntawm SiOC macroporous ceramics ntawm chav sov li ntawm 0.041 W · m-1 · K-1 txog 0.078 W · m-1 · K-1. Qhov ntsuas cua sov no tuaj yeem piv nrog cov ntawv qhia txog aluminium airgel. Piv nrog carbon airgel. Hais txog qhov ua tau zoo microstructure ntawm SiOC macroporous ceramics, cubic array interspersed nanosphere qauv piav qhia nws cov cua sov thauj khoom (raws li qhia hauv daim duab 1) tau npaj tseg thiab cov qauv theoretical rau kwv yees qhov txiaj ntsig thermal conductivity tau tsim. Cov kev tshawb fawb tau ceeb toom ntxiv tias qhov pom kev ua kom sov ntawm SiOC macroporous ceramics tsim los ntawm tib lub thermoelectric pyrolysis qhov kub tau cuam tshuam los ntawm theem theem ntim ib feem ntawm SiOC, thaum lub microstructure tsis ntawm SiOC macroporous ceramics muaj qhov sib txawv pyrolysis kub Lub ci ci, tshwj xeeb tshaj yog qhov piv txwv a/d ntawm qhov kov ntev ntawm qhov sib txuas ib sab mus rau qhov me me taub, yog lwm qhov tseem ceeb cuam tshuam rau nws cov cua sov thauj mus los.
