Tsuas yog cov kauj ruam no yog xav tau los txhim kho cov yeeb yaj kiab polyimide

Yuav ua li cas ua tau zoo ntawm polyimide zaj duab xis? Cia peb saib ua ke.

Polyimide zaj duab xis cov ntaub ntawv yog ib yam uas tsis tshua muaj kub tsis kam, corrosion kuj, mechanical zog, tsis tshua muaj dielectric zog, hluav taws xob kuj thiab high processability, yog li nws siv yog heev 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 hauv qhov chaw thiab qhov tsis muaj zog ntawm cov khoom siv hluav taws xob high-tech, hluav taws xob zoo li qub 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 tsis pub nws daim ntawv thov nyob rau hauv aerospace thiab ntau yam teb nyob rau hauv ntau yam, yog li kev hloov pauv ntawm cov khoom siv polyimide tau coj mus rau qhov ua ntej.

Graphene tau dhau los ua qhov tseem ceeb ntawm kev saib xyuas tam sim ntawd tom qab nws tau npaj rau xyoo 2004, thiab nws cov khoom siv hluav taws xob zoo heev, thermal conductivity thiab cov khoom siv tshuab yog txhua yam nyob rau hauv kev ua tau zoo. Ntxiv graphene rau cov khoom yuav txhim kho nws cov conductivity thiab thermal stability.

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. Lub siab kub tsis kam ntawm polyimide tuaj yeem ua kom lub cev decomposition thiab hloov pauv ntawm cov hlau dopant. Cov txheej txheem ntau yam ntawm polyimide tso cai rau cov txheej txheem doping kom muaj ntau yam. Tsis tas li ntawd, lub siab solubility ntawm polyamic acid kom muaj zog polar solvents yuav pab tau inorganic tshuaj zoo dua doped rau hauv polyimide zaj duab xis.

Yog li ntawd, hauv daim ntawv no, graphene tau muab tso rau hauv polyimide los hloov cov polyimide zaj duab xis los txhim kho txhua yam ntawm kev ua tau zoo ntawm polyimide zaj duab xis. Thawj qhov kev txiav txim siab thaum graphene tau muab tso rau hauv cov ntaub ntawv polyimide yog qhov dispersibility. Qhov tseeb, qhov dispersibility ntawm inorganic cov ntaub ntawv nyob rau hauv inorganic / polymer cov ntaub ntawv yog ib qho tseem ceeb heev, thiab uniformity ntawm dispersion tuaj yeem cuam tshuam rau cov ntaub ntawv sib xyaw ua ke. Kev ua tau zoo.

Kab lus no thawj zaug kawm txog kev sib koom ua ke ntawm graphene, tos ntsoov rau txoj kev sib xyaw kom zoo dua qub, thiab kuaj thiab ua kom pom qhov ua tau zoo ntawm cov yeeb yaj kiab sib xyaw. Nws cia siab tias qhov sib ntxiv ntawm graphene yuav cuam tshuam cov conductivity thiab thermal zog ntawm polyimide zaj duab xis. Thiab qee qhov lwm yam khoom muaj tseeb
