Cov ntaub ntawv Polymer muaj qhov zoo ntawm qhov ceev ceev, kev ua tau yooj yim, thiab rwb thaiv hluav taws xob zoo.Lawv tau siv dav hauv kev lag luam xws li microelectronics kev koom ua ke thiab ntim khoom, tshuab hluav taws xob, thiab LED txuag hluav taws xob.Feem ntau hais lus, polymers yog cov tsis zoo conductors ntawm tshav kub.Raws li cov ntaub ntawv insulating muaj kev txhawj xeeb, lawv lub peev xwm kub dissipation tau dhau los ua qhov teeb meem hauv lub cev, thiab yuav tsum tau ceev nrooj los npaj cov khoom siv thermal conductivity polymer nrog cov khoom zoo heev.

Silicon carbide muaj cov yam ntxwv ntawm corrosion kuj, kub tsis kam, siab zog, zoo thermal conductivity, cuam tshuam tsis kam, thiab lwm yam. Nyob rau tib lub sij hawm, nws muaj qhov zoo ntawm thermal conductivity, oxidation kuj, thiab zoo thermal stability.

Cov kws tshawb fawb tau siv silicon carbide ua cov thermal conductive muab tub lim los sau epoxy, thiab pom tias nano-silicon carbide tuaj yeem txhawb kev kho ntawm epoxy resin, thiab silicon carbide hais feem ntau yuav tsim txoj hauv kev thermal conduction lossis thermal network saw hauv cov txheej txheem cob. , txo qhov tsis muaj qhov sib piv ntawm epoxy resin thiab txhim kho epoxy resin.Mechanical thiab thermal conductivity ntawm cov khoom.

Qee cov kev tshawb fawb tau siv silane coupling tus neeg sawv cev, stearic acid thiab lawv cov kev sib xyaw ua ke los ntawm kev hloov kho los kawm txog cov teebmeem ntawm cov kev hloov pauv sib txawv ntawm cov khoom siv, cov nqi roj nqus thiab thermal conductivity ntawm β-SiC hmoov.Cov txiaj ntsig kev sim qhia tau hais tias qhov kev hloov pauv ntawm KH564 hauv silane coupling tus neeg sawv cev yog pom tseeb dua;los ntawm kev kawm ntawm stearic acid thiab kev sib xyaw ua ke ntawm ob qhov kev hloov kho saum npoo, cov txiaj ntsig tau pom tias qhov kev hloov kho tau zoo dua qub dua piv nrog cov hloov kho ib leeg, thiab qhov hardness siab dua.Cov nyhuv ntawm fatty acid thiab KH564 yog qhov zoo dua, thiab cov thermal conductivity nce mus txog 1.46 W / (m·K), uas yog 53.68% siab dua li ntawm unmodified β-SiC thiab 20.25% siab dua li ntawm ib zaug KH564 hloov.

Saum toj no rau koj siv nkaus xwb, cov ntsiab lus xav tau koj qhov kev sim, ua tsaug.
