Cov ntaub ntawv ua los ntawm biomass graphene tsis muaj qhov sib txawv ntawm kev sib chwv thiab cov ntaub, tab sis muaj qhov tshwj xeeb ntawm kev ua haujlwm xws li kev ua kom sov, bacteriostatic, tiv thaiv ultraviolet thiab deodorization. Nws tuaj yeem ua haujlwm ua lub tsev sov sov thiab txo qhov mob ntawm ncauj tsev menyuam. Txij li thaum electrothermal conversion efficiency ntawm graphene tuaj yeem ncav cuag 99%, nws muaj qhov zoo dua piv nrog lwm cov khoom siv hluav taws xob. Thib ob, cov khoom siv hluav taws xob ua kom sov, thiab nws yog qhov ua rau luv luv hluav taws xob, dej tsis muaj zog, thiab tib neeg kev nplij siab. |
1.Conductive number case Tus cwj mem conductive yog tus cwj mem ua los ntawm cov khoom siv hluav taws xob thiab muaj qee qhov kev coj ua, thiab tuaj yeem siv los ua cov ntawv luam tawm lossis cov kab hluav taws xob. Nyob rau hauv xyoo tas los no, nws tau dhau los ua ntau thiab siv ntau hauv kev lag luam xws li xov tooj ntawm tes, cov khoom ua si, membrane keyboards, solar cells, far-infrared heating films thiab radiofrequency identification technologies. Nyob rau hauv ob peb lub xyoo dhau los, qhov loj tshaj plaws downstream ntawm conductive inks yog hnub ci hlwb thiab cov khoom siv. Cov ntawv thov yav tom ntej suav nrog cov sensors kov thiab lawv cov electrodes, RFID thiab cov ntawv hluav taws xob tseem yuav loj tuaj. | |
2.Sensors Graphene muaj ntau yam kev siv hauv cov sensors vim nws cov qauv ob-seem tshwj xeeb. Nws muaj cov yam ntxwv ntawm cov ntim me me, qhov loj ntawm qhov chaw, siab rhiab heev, lub sij hawm teb ceev ceev, ceev electron hloov, yooj yim kho cov proteins thiab tswj nws cov haujlwm. Yam khoom ua haujlwm. Feem ntau siv rau hauv kev tsim cov pa roj, bio-me me molecules, enzymes thiab DNA electrochemical sensors. Nanyang Technological University hauv Singapore tau tsim graphene lub teeb sensor nrog rhiab heev ntawm 1000 npaug ntawm cov pa sensor; Rensselaer Polytechnic lub koom haum ntawm Tebchaws Meskas tau tsim ib qho pheej yig graphene sponge sensor uas deb tshaj li cov khoom lag luam uas twb muaj lawm. 3. Cov khoom siv roj ntsha Graphene cov ntaub ntawv muaj ntau yam kev siv nyob rau hauv biological teb. Ntawm lawv, graphene oxide tuaj yeem ua rau hauv cov ntaub ntawv nano-antibacterial, thiab nws cov cuab yeej tiv thaiv kab mob tshwm sim los ntawm kev puas tsuaj ntawm E. coli cell membrane. Vim nws cov khoom siv nplua nuj, cov khoom siv lead ua tshiab no yuav tsum tau siv dav hauv kev tshawb nrhiav ib puag ncig thiab tshuaj kho mob. 4. Cov khoom siv hluav taws xob cia Graphene kuj tseem ua lub luag haujlwm tseem ceeb hauv kev cia lub zog. Hydrogen ib txwm tau suav tias yog lub zog zoo heev. Txawm li cas los xij, vim nws qhov chaw ntom ntom ntom tsawg thiab tawg, hydrogen cia cov khoom siv tau ib txwm yog qhov chaw kub rau kev tshawb fawb. Graphene Qhov tshwm sim ntawm cov ntaub ntawv hauv chav kawm yuav siv dav hauv hydrogen zog cia. 5. Lithium roj teeb Graphene yog dav siv nyob rau hauv lithium ion roj teeb. Nws tau raug coj mus muag ua cov khoom siv ntxiv hauv cov khoom siv cathode txhawm rau txhim kho cov khoom siv hluav taws xob thiab txhim kho tus nqi kev ua haujlwm thiab lub neej voj voog. Tam sim no, daim ntawv thov paub ntau dua yog siv graphene los ua cov tshuaj pleev xim rau cov khoom siv qib zoo xws li hlau phosphate. Tam sim no, txheej slurry rau ib tug zoo electrode feem ntau muaj xws li ib tug graphite slurry, ib tug carbon nanotube slurry, thiab lwm yam, thiab nrog rau loj zus tau tej cov graphene hmoov thiab graphene microchip hmoov, graphene muab tshuaj txhuam yog tso tawm ntau thiab tus nqi yog pheej yig dua. Cov txheej txheem zoo. Raws li cov roj teeb lithium loj tuaj, graphene pastes yuav nce tsis tu ncua. Cov roj teeb lithium-ion feem ntau yog siv rau hauv cov khoom siv hluav taws xob, xws li xov tooj ntawm tes, khoos phis tawj thiab cov koob yees duab video, thiab nquag nthuav dav mus rau hauv lub zog tshiab xws li tsheb hluav taws xob, thiab muaj kev cia siab rau kev loj hlob mus ntev. 6. Cov khoom siv semiconductor Graphene yog suav tias yog cov khoom siv zoo tshaj plaws rau kev hloov silicon, thiab ntau lub tuam txhab muaj zog tau tsim cov khoom siv graphene semiconductor. Sungkyunkwan University hauv Kaus Lim Kauslim tau tsim lub siab ruaj khov n-hom graphene semiconductor uas tuaj yeem siv rau hauv huab cua ntev. Columbia University tau tsim ib lub graphene-silicon optoelectronic hybrid nti, uas muaj dav daim ntawv thov kev cia siab nyob rau hauv lub tshav pob ntawm optical interconnects thiab low-power photonic integrated circuits. IBM cov kws tshawb fawb tau tsim graphene teb-zoo transistors nrog kev txiav tawm zaus mus txog 100 GHz thiab kev ua haujlwm zaus zoo tshaj qhov kev txiav tawm zaus (40 GHz) ntawm cov qib siab tshaj plaws silicon transistors ntawm tib lub rooj vag ntev.
