Kev tshawb fawb keeb kwm
Cov ntaub ntawv hloov pauv theem (PCMs) tau siv dav hauv kev tswj xyuas qhov kub thiab txias, siv cov khoom siv hluav taws xob pov tseg thiab cov cua sov dissipation hauv cov khoom siv hluav taws xob vim lawv cov phooj ywg ib puag ncig thiab kev ruaj ntseg. Ntawm ntau hom PCMs, organic PCMs (OPCMs) xws li polyethylene glycol (PEG) thiab paraffin wax muaj ntau dua enthalpy ntawm cov theem hloov, tsim nyog theem hloov kub ntau, qis corrosiveness, non-toxicity thiab zoo thermal stability, thiab yog li ntawd feem ntau siv dua lwm hom PCMs. Txawm li cas los xij, qhov qis thermal conductivity thiab qhov xav tau los ntawm cov ntsiab lus melting ntawm OPCMs yog qhov cuam tshuam loj rau lawv daim ntawv thov loj. Raws li qhov tshwm sim, pawg tau tshawb fawb dav dav txog cov teeb meem no.
Tshooj Lus Taw Qhia
Tsis ntev los no, ib qho tshiab carbonized melamine ua npuas ncauj / txo graphene oxide coated tooj liab network (MF / rGO / Cu-C) tau npaj los ntawm Prof. Zou Yongjin thiab Prof. Sun Lixian pawg ntawm Guilin University of Electronic Science thiab Technology rau kev tsim kho ntawm cov khoom siv ntau yam OPCMs. PEG raug xaiv los ua cov khoom siv thermal thiab cov khoom sib xyaw OPCMs (PEG@MF/rGO/Cu-C) tau npaj rau hauv tsab xov xwm los ntawm lub tshuab nqus tsev impregnation. pEG@MF/rGO/Cu-C muaj lub siab melting enthalpy (148.3 J g-1) thiab crystallization enthalpy (143.9 J g-1). Tsis tas li ntawd, nws cov thermal conductivity mus txog 0.4621 W m-1K-1, kev txhim kho ntawm 463% piv rau PEG@MF. Cov khoom sib xyaw OPCMs kuj pom zoo cov duab-thermal thiab electro-thermal hloov dua siab tshiab thiab yog li ntawd muaj peev xwm rau ntau yam kev qhuab qhia.
Graphic Analysis
- GO yog loaded nyob rau hauv MF (melamine npuas) 3D moj khaum los ntawm kev daws impregnation kom tau MF / GO network; Tom qab ntawd, MF / GO yog cov tshuaj tooj liab plated thiab GO raug txo ib txhij thaum lub sij hawm tooj liab plating kom tau MF / rGO / Cu; Tom qab ntawd, MF / rGO / Cu network yog carbonised ntawm qhov kub thiab txias kom tau txais MF / rGO / Cu-C; Thaum kawg, PEG yog nqus impregnated los ntawm tau ntim hauv MF / rGO / Cu-C kom tau txais PEG @ MF / MF / rGO / Cu-C composite OPCMs.
- Lub morphology ntawm cov khoom raug soj ntsuam siv SEM. templateing kev txiav txim ntawm MF ua rau MF / GO, MF / rGO / Cu thiab MF / rGO / Cu-C tag nrho muaj cov qauv zoo sib xws 3D porous mesh. Tsis tas li ntawd, kev ua tiav kev thauj khoom ntawm Cu hais tuaj yeem pom los ntawm SEM cov duab.
- Cov txiaj ntsig ntawm XRD, FT-IR thiab XPS kev txheeb xyuas pom tau tias muaj kev vam meej ntawm kev thauj khoom ntawm tooj liab thiab kev ua tiav ntawm GO.
- Cov theem hloov tus cwj pwm ntawm OPCMs tau tshawb xyuas siv DSC. Lub DSC nkhaus ntawm txhua qhov sib xyaw OPCMs zoo ib yam li cov PEG ntshiab, muaj lub ncov melting thiab crystallisation ncov, qhia tias kev taw qhia ntawm cov cab kuj tsis hloov pauv tus cwj pwm crystallisation ntawm PEG. Tsis tas li ntawd, kev taw qhia ntawm rGO thiab Cu thiab kev kho carbonization tau txhim kho cov thermal conductivity ntawm lub network.
- PEG@MF/rGO/Cu-C muaj peev xwm yees duab- thiab electro-thermal hloov dua siab tshiab.
