Raws li ib feem tseem ceeb ntawm lub teb chaws txoj kev ua haujlwm tawm ntawm kev lag luam, kev lag luam silicone muaj peev xwm loj heev. Txawm li cas los xij, cov ntawv thov tam sim no tau txais ntawm cov khoom ntim silicone yog qhov tsawg. Tsis ntev los no, ntawm 2024 Silicon-based tshiab cov ntaub ntawv thev naus laus zis thiab cov kws tshaj lij kev lag luam muaj kev sib tham los ntawm cov khoom lag luam uas muaj kev tshawb fawb thiab thev naus laus zis, ua tiav cov txheej txheem thev naus laus zis hauv Cov tsoos silicone kev lag luam, thiab iterate kev ua tau zoo ntawm silicone cov ntaub ntawv yuav tsum tau los ntawm kev lag luam tawm, thiab txhawb nqa cov kev lag luam silicone rau "tshiab" tawg.
Ib tug. Silicone kom muaj kev nyab xeeb ntawm cov roj teeb
Nrog kev hloov pauv ntawm lub zog thoob ntiaj teb qauv thiab kev txhim kho sai ntawm kev siv hluav taws xob sai, qhov kev thov kom txuag hluav taws xob cia khoom yog loj hlob. FEI HUAFEN, tus kws tshawb fawb nyob rau hauv lub koom haum Chemistry, suav nrog cov roj ntsha, cov roj teeb hluav taws xob muaj zog muaj zog thiab kev nyab xeeb dua. Polysiloxane, raws li cov khoom siv polymer electrolyte, muaj cov tshuaj ruaj khov, dav ntau ntau yam yooj yim, thiab tsis muaj txiaj ntsig. Nws muaj cov ntawv thov zoo nyob rau hauv cov khoom siv hluav taws xob thiab yuav tsum tau siv hauv kev sib xyaw ua ke khoom thiab txawm tias muaj kev tswj hwm nano-micro interface lub zog.
"Tam sim no, Polysiloxane-raws cov khoom electrolytes tseem yuav tsum tau kov yeej cov teeb meem nyuaj xws li chav qis, tswj tsis tau muaj zog." FEI HUAFENM tau hais tias lawv siv polysiloxane raws li cov khoom siv polysiloxane ntawm polystricous salts, daws cov teeb meem ntawm nws cov kev ua tau zoo, thiab Ua kom muaj kev sib nraus lithium ion tsiv teb tsaws chaw ntawm electrolyte, li kev txhim kho nplaim retardant cov khoom thiab txhim kho cov roj teeb kev ua tau zoo.
Daim ntawv thov ntawm siab thermal colestivity cov ntaub ntawv hauv cov roj teeb lithium-ion yog qhov tseem ceeb rau kev txhim kho cov roj teeb kev nyab xeeb thiab nthuav teeb lub roj teeb. Kev siv cov nplaim hluavtaws-retardant thermal cov ntaub ntawv los encapsulate cov roj teeb hluav taws xob muaj peev xwm tswj tau roj teeb thiab ua kom muaj kev nyab xeeb sov. Zheng miaosheng, cov ntaub ntawv dav dav ntawm Kaibo Cov ntaub ntawv tshiab (Tianjin) Co., Ltd. Cov huab cua zoo heev thiab lwm yam khoom, thiab yog dav Siv lub zog tshiab, tsheb, khoom siv hauv tshuab hluav taws xob thiab lwm thaj teb. Raws li cov khoom siv hluav taws xob tsim kom muaj zog ntau dua thiab me dua, qhov kev thov rau thermal kev coj ua silicone gel yuav txuas ntxiv ntxiv rau yav tom ntej.
Ob. Silicone roj hmab ua tiav kev kho tus kheej thiab tsim dua tshiab
Cov khoom siv roj hmab silicone tau pom nyob rau sab nraud cov ntaub ntawv rwb thaiv tsev qhwv li cov kab thiab cov khoom siv hluav taws xob. Li Xiyu, Tus Thawj Coj ntawm Xi'an High Voltage Cov Khoom Siv Hluav Taws Xob, taw qhia cov khoom siv rwb thaiv tsev, ua cov teeb meem tseem ceeb hauv ac thiab dc cov teeb meem phlu. Nrog rau kev nce ua txuas ntxiv hauv kev siv thiab kev pabcuam lub neej, yuav ua li cas kom tau txais txiaj ntsig zoo ntawm cov roj hmab silicone roj hmab yog qhov teeb meem kev lag luam ceev yuav tsum kawm.
Xib fwb Xiang Hongping ntawm Guangdong University of Technology tseem tau taw qhia tias Silicone roj hmab muaj teeb meem xws li kev tawg thaum siv tom qab muab tso tawm tom qab pov tseg. Txawm hais tias muaj ntau yam ntawm tus kheej-kho thiab rov qab ua dua silicone rub tawm tau tsim, cov khoom tseem feem ntau muaj teeb meem xws li cov tshuab hluav taws xob muaj zog. Hauv kev teb rau qhov no, Xiang Hongping pawg tau npaj siab siv lub tswv yim zoo, kev kho tus kheej, thiab cov roj hmab ua kom zoo dua qub. Sab saw amino silicone roj (PDMS-NH2) tau sib xyaw siv cov qauv catalyatic. PDMS-NH2 tau sib xyaw nrog P-Carboxyldehyde ua kom cov pab pawg aldehyde los tsim dual dynamic cross-sib txuas thiab ionine hydrogen bonds). Silicone roj hmab ua tiav thim rov qab tawg thiab kev ua kom zoo nkauj hauv kev pab cuam thiab ionic hydrogen bonds, pub cov roj hmab hydrogen ntawm tus kheej thiab tsim dua tshiab.
"Txij li lub zog khi hluav taws xob ntawm ionic hydrogen bonds yog tsawg, thaum cov roj hmab silicone yog deforment nyob rau hauv kev ntxhov siab, uas ua lub luag haujlwm nyob rau hauv kev ntxhov siab, tus Ionic Hydrogen Bonds yuav rov ua dua tshiab thiab tawg tsis tu ncua, uas yog tus kheej kho lub luag haujlwm thiab rov qab ua dua ntau zaus, uas tuaj yeem txuas ntxiv cov kev pabcuam lub neej ntawm cov khoom siv. " Xiang hongping tau hais.
Peb. Kev tsim kho cov khoom lag luam silicone hauv ntau thaj teb
Kuv lub teb chaws yog lub ntiaj teb loj tshaj plaws ntawm silicone thiab nyob hauv ntiaj teb silicone thiab piv nrog cov teb chaws kev tsim khoom, Kuv lub teb chaws nyob rau ib tus capita silicone noj tseem lag ua lags.
"Kev txhim kho ntawm cov khoom lag luam tshiab organosilici tuaj yeem nthuav tawm cov khoom siv organosilicon thiab txhawb nqa cov khoom lag luam organosilicon, ua rau muaj cov khoom siv rau cov organosiailicon, tshwm sim hauv cov organosilicon." Wang Dengxu, a professor at Shandong University, introduced that they used new organosilicon synthesis methods such as the Heck reaction and multi-component reaction to construct a variety of new organosilicon materials such as organosilicon porous (fluorescent) materials and amphiphilic organosilicon polymers, which is Cia siab tias yuav ua tiav kev ua haujlwm zoo ntawm orgongosilicon cov ntaub ntawv thiab cov khoom siv roj carbon.
Zhuo Shengchi, Tus Thawj Coj ntawm Changxing cov ntaub ntawv (Suzhou) Lub Chaw Haujlwm Tshawb Fawb, cov qauv kev tshawb nrhiav tau npaj tau los ntawm cov qauv sol-gel, emulsion polymerization thiab lwm txoj kev. Cov khoom siv silicone no tuaj yeem nthuav tawm lub teeb pom kev zoo hauv cov teeb pom kev zoo thiab cov teeb meem zoo nkauj rau hauv cov teeb meem teeb pom kev zoo. Hauv cov tshuaj pleev ib ce, lub teeb tawg ntawm cov khoom ntawm cov khoom siv silicone facebooker tuaj yeem muab kov thiab kev sib tw zoo; Nyob rau hauv daim duab ntawm txheej, cov hnav tsis kam thiab kub ua rau ntawm silicone jookpheres tuaj yeem txhim kho kev ua tau zoo ntawm cov txheej txheem.
"Kuv lub teb chaws muaj cov zis loj heev ntawm silicone monomers, thiab raws li, ntau txhiab tus metylardichlorosilane los ntawm cov khoom lag luam yog tsim txhua xyoo." Yias Jiayan, Tus Thawj Coj ntawm Kev Koom Tes Technology ntawm Jiangxi Roj Cov Khoom Siv, Polyether-Modified Silicone Roj thiab lwm yam tshuaj lom neeg silicone, uas yog siv tshuaj tua kab, cov tshuaj txhua hnub , textiles thiab lwm daim teb, yog li paub txog qhov rov ua dua tshiab ntawm cov khoom lag luam.
