Yuav ua li cas txhim kho kev ua tau zoo ntawm polyimide zaj duab xis

Kev ua tau zoo ntawm polyimide zaj duab xis yog qhov kev txhawj xeeb zoo rau cov neeg siv khoom thiab cov phooj ywg uas xav siv nws. Yog tias peb xav ua kom tau raws li peb cov kev xav tau tiag tiag, peb yuav tsum nkag siab meej tias yuav ua li cas txhawm rau txhim kho kev ua tau zoo ntawm polyimide zaj duab xis. Hauv qab no, kev tshaj lij Cov chaw tsim khoom tau muab cov lus qhia, cia peb saib nws kom meej.

Polyimide zaj duab xis cov ntaub ntawv muaj cov cua kub tsis kam, corrosion kuj, txhua yam khoom, tsis tshua muaj dielectric zog, hluav taws xob tsis kam thiab ua haujlwm siab, yog li lawv tau siv dav thiab nrov. Nws kuj tseem muaj txiaj ntsig zoo rau kev thov hauv thaj chaw aerospace.

Txawm li cas los xij, vim qhov chaw tshwj xeeb ntawm qhov chaw thiab qhov tsis muaj zog ntawm cov khoom siv hluav taws xob high-tech, hluav taws xob zoo li qub tau ua rau muaj kev puas tsuaj loj rau cov khoom siv dav hlau thiab cov khoom siv hluav taws xob. Lub conductivity ntawm polyimide zaj duab xis nws tus kheej yog tsawg heev, uas txwv nws daim ntawv thov nyob rau hauv aerospace thiab ntau yam teb nyob rau hauv ntau yam. Yog li ntawd, kev kho thiab hloov kho cov ntaub ntawv polyimide tau coj mus rau pem hauv ntej.

Txij li thaum nws qhov kev npaj hauv xyoo 2004, graphene tau dhau los ua qhov tseem ceeb ntawm kev saib xyuas thoob plaws ntiaj teb, thiab nws cov khoom siv hluav taws xob zoo heev, thermal conductivity thiab mechanical zog yog qhov zoo tshaj plaws. Graphene tuaj yeem txhim kho cov conductivity thiab thermal stability ntawm cov khoom.

Qee qhov kev hloov kho ntawm cov hlau dopant doped hauv cov khoom siv polymer sib xyaw yuav tsum tau nqa tawm ntawm qhov kub thiab txias. Qhov kub tsis kam ntawm polyimide tuaj yeem ua kom lub cev decomposition thiab hloov pauv ntawm cov hlau dopant. Ntau txoj kev sib txuas ntawm polyimide tuaj yeem ua kom muaj ntau txoj hauv kev doping. Tsis tas li ntawd, lub siab solubility ntawm polyamic acid nyob rau hauv muaj zog polar solvents yuav pab tau inorganic tshuaj zoo dua doped rau hauv lub polyimide zaj duab xis.

Yog li ntawd, nyob rau hauv daim ntawv no, graphene yog doped rau hauv polyimide los hloov cov polyimide zaj duab xis, yog li no comprehensively txhim kho cov kev ua tau zoo ntawm polyimide zaj duab xis. Thaum graphene tau muab tso rau hauv cov ntaub ntawv polyimide, dispersion yog thawj qhov kev xav. Nyob rau hauv qhov tseeb, dispersion ntawm inorganic tshuaj nyob rau hauv cov ntaub ntawv inorganic/polymer yog ib qho tseem ceeb heev, thiab cov uniformity ntawm dispersion yuav cuam tshuam rau kev ua tau zoo ntawm kev npaj composite membrane. Nyob rau hauv daim ntawv no, cov txheej txheem ntawm kev koom ua ke ntawm graphene yog thawj zaug kawm, thiab ib txoj kev sib tov zoo yog prospected. Tom qab ntawd, qhov kev ua tau zoo ntawm cov khoom sib xyaw ua ke tau raug sim thiab ua kom pom tseeb. Nws xav tias qhov sib ntxiv ntawm graphene yuav txhim kho cov conductivity thiab thermal zog ntawm polyimide zaj duab xis.
