Graphene Fluoride hmoovyog ib yam tshiab tseem ceeb ntawm graphene derivative. Piv nrog rau graphene, fluorinated graphene, txawm hais tias hom hybridization ntawm carbon atoms hloov los ntawm sp2 mus rau sp3, nws tseem khaws cov qauv lamellar ntawm graphene. Yog li ntawd, fluorinated graphene tsis tsuas yog muaj qhov loj ntawm thaj chaw raws li graphene, tab sis tib lub sijhawm, kev qhia txog fluorine atoms zoo heev txo lub zog saum npoo ntawm graphene, zoo heev txhim kho hydrophobic thiab oleophobic zog, thiab txhim kho thermal stability, tshuaj stability thiab kuj. . Corrosion peev xwm. Cov khoom tshwj xeeb ntawm fluorinated graphene no ua rau nws siv dav hauv kev hnav, lubricating, kub-resistant corrosion-resistant coatings, thiab lwm yam. Nyob rau tib lub sij hawm, vim qhov ntev band sib txawv ntawm fluorinated graphene, nws yog siv nyob rau hauv nanoelectronic li, optoelectronic. cov khoom siv, thiab cov khoom siv thermoelectric. Lub teb muaj peev xwm thov kev cia siab. Tsis tas li ntawd, vim tias cov khoom siv fluorinated graphene-based fluorocarbon muaj cov qauv tsim tshwj xeeb thiab qhov pore, thiab qhov sib txawv ntawm cov ntsiab lus fluorine muaj cov qauv siv hluav taws xob hloov tau, nws muaj cov khoom siv hluav taws xob tshwj xeeb thiab siv hauv cov ntaub ntawv lithium thawj roj teeb cathode. Nws muaj cov yam ntxwv ntawm kev sib cuag loj nrog electrolyte thiab ceev lithium ion diffusion. Cov roj teeb lithium thawj siv cov roj fluorinated zoo li cov khoom siv cathode muaj qhov zoo ntawm lub zog hluav taws xob, ntau yam kev tawm hauv lub zog, thiab cov khoom siv ntev ntev. , Nws muaj peev xwm siv tau zoo hauv aerospace thiab high-end pej xeem teb.
