Cov haujlwm ntawm Graphene Fiber Fabric

1.Dab tsi yog graphene fiber ntau?

Graphene yog ib qho siv lead ua ob sab uas tsuas yog ib qho atom tuab thiab ua los ntawm cov pa roj carbon atoms tawm ntawm cov khoom siv graphite. Graphene yog cov khoom thinnest thiab muaj zog tshaj plaws nyob rau hauv cov xwm. Nws yog 200 npaug zog dua hlau. Tsis tas li ntawd nws muaj zoo elasticity. Nws qhov tensile amplitude tuaj yeem ncav cuag 20% ​​ntawm nws qhov loj me. Txog tam sim no, nws yog lub thinnest thiab muaj zog tshaj tshiab nanomaterial nrog lub zog tshaj hluav taws xob thiab thermal conductivity.

2.Kev ua haujlwm ntawm graphene fiber ntauntaub

(1) Tsawg kub infrared kev ua haujlwm:

Tom qab sib xyaw nrog cov khoom siv biomass graphene, lub endowarm fiber yog ntxiv dag zog rau qhov nqus noo noo thiab huab cua permeability.viscose fiber ntau. Npuag ntawm endowarm fiber yog ci thiab mos. Nws muaj kev xav qhuav thiab du tes. Nws tsis yooj yim kom ploj mus. Nyob rau tib lub sijhawm, nws zoo kawg nkaus qhia txog kev ua tau zoo ntawm biomass graphene, ntawm cov uas pom tseeb tshaj plaws yog txhawm rau txhim kho cov nyhuv ntawm lub cev kub nyob deb infrared. Qhov ntawd yog qhov kub ntawm 20 ~ 35 ℃, nws qhov deb infrared lub teeb haum ntawm (6 ~ 14) μm yoj yog ntau dua 88%. Kev ua haujlwm zoo ntawm lub cev kub nyob deb infrared ntawm endowarm fiber ntau textile yog los pab ua kom cov tawv nqaij ntawm qhov kub thiab txias, uas ua rau lub capillaries, txhim kho lub cev microcirculation, ntxiv dag zog rau cov metabolism ntawm cov ntaub so ntswg, dredge lub meridians thiab txhim kho kev tiv thaiv kom ua tiav cov txiaj ntsig kev noj qab haus huv. ntawm tib neeg lub cev.

(2) Antibacterial thiab bacteriostatic zog:

Ntau hom kab mob ua raws li graphene paj rwb txhob lo lo ntxhuav ntaub. Lub graphene txiav cov cytomembrane los ntawm nws cov ciam teb ntse thiab tom qab ntawd cov superoxide ions nruab nrab oxidative kev nyuaj siab thiab thaum kawg cov kab mob tuag. Tsis tas li ntawd, graphene tuaj yeem ncaj qha rho tawm phospholipid molecules los ntawm cov cell membranes ntawm cov nplai loj thiab ua rau cov membranes puas los tua cov kab mob. Graphene muaj kev ua haujlwm zoo los tiv thaiv kab mob thaum cuam tshuam nrog cov kab mob. Tab sis nws pom tsuas yog tsis muaj zog cytotoxicity thaum cuam tshuam nrog cov hlwb lossis kab mob. Nws txhais tau hais tias graphene yog ib hom nanomaterial nrog ob qho tib si tshuaj tua kab mob thiab biocompatible, uas muaj peev xwm siv tau zoo hauv biomedical textiles.

(3) Anti-static thiab anti-electromagnetic zog:

Cov hluav taws xob conductivity ntawm graphene yog 1 × 10⁶S/m. Nws yog cov khoom siv hluav taws xob zoo. Graphene muaj hluav taws xob muaj zog heev. Lub electron txav ntawm graphene dav hlau tuaj yeem ncav cuag 1.5 x 10⁵cm / (V·s), uas yog 100 lub sij hawm siab dua li cov khoom siv silicone zoo tshaj plaws tam sim no. Yog li ntawd, ntxiv graphene rau sab hauv ntawmfiber ntauyuav txhim kho cov khoom tiv thaiv zoo li qub ntawm fiber ntau. Ntxiv graphene yuav degrease tshwj xeeb kuj ntawm fiber ntau nto thiab tseem yuav impart fiber nto ib co smoothness thiab txo cov kev sib txhuam, thiaj li inhibit thiab txo electrostatic nqi.

(4) Anti-ntxuav, noo noo nqus thiab noo noo conductivity kev ua tau zoo:

Graphene yog ob-dimensional periodic cellular lattice qauv tsim los ntawm cov pa roj carbon rau-membered rings, uas yuav warped rau hauv xoom-dimensional fullerenes, dov rau hauv ib-dimensional carbon nanotubes los yog stacked rau hauv peb-dimensional graphite. Vim nws qhov chaw ob sab, nws muaj peev xwm nqus dej tshwj xeeb. Thiab nws yuav ua kom zoo tom qab hnav thiab ntxuav ntau zaus.
