Balaastigga kuleylka sarreeya waxay muujinayaan karti aan caadi ahayn oo ku saabsan inductors-ka beddelka, diridda kulaylka qaybta elektiroonigga ah, fiilooyinka gaarka ah, baakadaha elektiroonigga ah, dheriga kulaylka iyo meelaha kale ee waxqabadkooda habaysan ee wanaagsan, qiimo jaban iyo kulaylka heersare ah.Balaastigga kuleylka sare leh oo leh graphene sida buuxintu waxay buuxin kartaa shuruudaha cufnaanta sare iyo horumarinta isku dhafka sare ee maamulka kuleylka iyo warshadaha elektiroonigga ah.

Caadooyinka kuleylka caadiga ah waxaa inta badan ka buuxsamay bir kuleylkeedu sarreeyo ama walxaha buuxinta unugyada si ay si isku mid ah u buuxiyaan walxaha matrixka polymer.Marka qadarka wax-buuxiyuhu gaadho heer gaar ah, buuxintu waxa ay samaysaa qaab-dhismeedka silsilad-u-ekaanta iyo qaab-dhismeedka isku-xidhka ee nidaamka, taas oo ah, silsilad shabakad kuleyl leh.Marka jihada jihada ee silsiladaha mesh-hawlgalayaasha kulaylka ay barbar socdaan jihada socodka kulaylka, kuleylka kuleylka ee nidaamka ayaa si weyn loo wanaajiyay.

balaastiig heerkul sare leh oo lehgraphene kaarboon nanomaterialmaadaama buuxintu uu buuxin karo shuruudaha cufnaanta sare iyo horumarinta isku-dhafka sare ee maamulka kuleylka iyo warshadaha elektiroonigga ah.Tusaale ahaan, kuleylka kuleylka ee polyamide saafi ah 6 (PA6) waa 0.338 W / (m · K), marka la buuxiyo 50% alumina, kuleylka kuleylka ee isku-dhafka ah waa 1.57 jeer ka badan PA6 saafi ah;marka lagu daro 25% zinc oxide ee la beddelay, kuleylka kuleylka ee isku-dhafka ayaa saddex jeer ka sarreeya kan PA6 saafi ah.Marka 20% graphene nanosheet lagu daro, kuleylka kuleylka ee isku-dhafka wuxuu gaarayaa 4.11 W / (m•K), kaas oo kordhay in ka badan 15 jeer marka loo eego PA6 saafi ah, taas oo muujinaysa awoodda weyn ee graphene ee maareynta kulaylka.

1. Diyaarinta iyo dhaqdhaqaaqa kulaylka ee isku-dhafka graphene/polymer

Dhaqdhaqaaqa kulaylka ee isku-dhafka graphene/polymer waa mid aan kala sooc lahayn xaaladaha habaynta ee habka diyaarinta.Hababka diyaarinta ee kala duwan waxay sameeyaan farqi u dhexeeya kala firdhinta, ficilka isdhexgalka iyo qaab dhismeedka boosaska buuxinta ee matrixka, iyo arrimahan ayaa go'aaminaya qallafsanaanta, xoogga, adkaanta iyo ductility ee isku dhafan.Ilaa hadda inta ay khusayso cilmi-baadhista hadda jirta, isku-dhafka graphene/polymer, heerka kala firdhisanaanta graphene iyo heerka diirinta xaashida graphene waxa lagu xakamayn karaa iyada oo la xakameynayo xiirid, heerkulka iyo dareerayaasha dabaysha.

2. Qodobbada saameeya waxqabadka graphene waxay buuxiyeen balaastikada kuleylka sare

2.1 Qadarka lagu daro ee Graphene

In caag heer sare ah oo ka buuxsamay graphene, sida tirada graphene kordho, silsilad network conductive kulaylka ayaa si tartiib tartiib ah u samaysmay nidaamka, taas oo si weyn u hagaajinaysaa conductivity kulaylka ee walxaha isku dhafan.

Iyadoo la baranayo kuleylka kuleylka ee resin epoxy (EP) -ku salaysan graphene composites, waxaa la ogaaday in saamiga buuxinta ee graphene (qiyaastii 4 lakab) ay kordhin karto kuleylka kuleylka ee EP qiyaastii 30 jeer ilaa 6.44.W/(m•K), halka fuliyeyaasha dhaqameedku ay u baahan yihiin 70% (jajabka mugga) buuxinta si loo gaaro saamayntan.

2.2 Tirada lakabyada Graphene
Graphene multilayers, daraasadda 1-10 lakabyada graphene waxay ogaatay in markii tirada lakabyada graphene laga kordhiyay 2 ilaa 4, kuleylka kuleylka ayaa hoos u dhacay 2 800 W / (m•K) ilaa 1300 W / (m•K) ).Waxay raacdaa in kuleylka kuleylka ee graphene uu u janjeero inuu hoos u dhaco kororka tirada lakabyada.

Tani waa sababta oo ah graphene multilayer ayaa sii xumaan doona wakhti, taas oo keeni doonta in kulaylka kuleylka hoos u dhaco.Isla mar ahaantaana, cilladaha ku jira graphene iyo khalkhalka cidhifka ayaa yareyn doona kuleylka kuleylka ee graphene.

2.3 Noocyada substrate
Qaybaha ugu muhiimsan ee caagadaha kulaylka sare leh waxaa ka mid ah qalabka matrixka iyo buuxinta.Graphene waa doorashada ugu fiican ee buuxinta sababtoo ah kuleylkeeda kulaylka wanaagsanPolyamide (PA) waxay leedahay sifooyin farsamo oo wanaagsan, iska caabbinta kulaylka, xidhashada iska caabbinta, iskuxiran hoose oo hooseeya, dib u dhacyada ololka qaarkood, habaynta fudud, ku habboon buuxinta beddelka, si loo hagaajiyo waxqabadkeeda oo loo ballaariyo goobta codsiga.

Daraasadu waxay ogaatay in marka jajabka mugga graphene uu yahay 5%, kuleylka kuleylka ee isku dhafan uu 4 jeer ka sarreeyo kan polymer-ka caadiga ah, iyo marka jajabka mugga graphene la kordhiyo ilaa 40%, kuleylka kuleylka ee isku-dhafka. waxaa lagu kordhiyey 20 jeer..

2.4 Habaynta iyo qaybinta graphene ee matrixka
Waxaa la ogaaday in jaangooyooyinka toosan ee graphene ay hagaajin karto kuleylka kuleylka.
Intaa waxaa dheer, qaybinta buuxinta shaxanka ayaa sidoo kale saameynaya kuleylka kuleylka ee isku-dhafka.Marka fiiliyuhu si isku mid ah ugu kala firdhiyo shaxanka oo uu sameeyo silsilad shabakad kuleyl leh, tamarta kulaylka ee isku-dhafka ayaa si weyn loo wanaajiyay.

2.5 iska caabin Interface iyo xoog isku xidhka interface
Guud ahaan, iswaafajinta is-waafajinta ee udhaxeysa qaybaha filler-ka aan organic iyo matrix resin organic waa liidata, iyo walxaha buuxinta ayaa si fudud loogu daraa shaxanka, taas oo adkeynaysa in la sameeyo kala firdhisan isku mid ah.Intaa waxaa dheer, farqiga u dhexeeya xiisadda dusha sare ee udhaxeysa qaybaha fillerka aan noolaha ahayn iyo matrixku waxay adkeyneysaa in dusha sare ee walxaha buuxinta ay ku qoyaan matrixka resin, taasoo keentay faaruq ah isdhexgalka labada, taas oo kordhinaysa caabbinta kulaylka interfacial. ee isku-dhafka polymer.

3. Gabagabo
Balaastigga kuleyliyaha sare ee ay ka buuxaan graphene waxay leeyihiin kuleylka kuleylka sare iyo xasilloonida kulaylka wanaagsan, rajada koritaankoodu aad bay u ballaaran tahay.Ka sokow conductivity kaamerada, graphene waxay leedahay sifooyin kale oo aad u fiican, sida xoog sare, guryaha sare ee koronto iyo indhaha, waxaana si ballaaran loo isticmaalaa in qalabka mobile, hawada, iyo baytariyada tamarta cusub.
