Nyob rau hauv xyoo tas los no, cov lus xws li "graphene", "heat" thiab "far-infrared life light waves" tau tshwm sim ntau zaus hauv peb lub neej. Ntau tus neeg hais tias cov cua sov tsim los ntawm graphene tuaj yeem nqus tau zoo dua los ntawm tib neeg lub cev. Koj puas paub tias graphene ua kom sov li cas?

Yuav kom nkag siab yooj yim, graphene cua sov yog txheej txheem ntawm kev hloov hluav taws xob hluav taws xob rau hauv thermal zog.

Tom qab cov graphene cua sov zaj duab xis yog energized, cov pa roj carbon molecules nyob rau hauv hluav taws xob cua sov zaj duab xis tsim phonons, ions thiab electrons nyob rau hauv lub kuj. Cov pab pawg carbon molecular uas tsim los rub tawm ib leeg thiab sib tsoo nrog ib leeg los ntawm "Brownian motion" los ua kom muaj zog cua sov. Nyob rau hauv cov txheej txheem no, vim lub siab thermal conductivity (5300W / mK) thiab tsis tshua muaj hluav taws xob muaj peev xwm ntawm graphene nws tus kheej, tom qab graphene yog energized, nws tsuas yog yuav tsum tau tsim ib tug me me cua sov kom nws kub thiab sai hloov lub tshav kub tawm. Ib feem ntawm lub zog hluav taws xob yog xa tawm mus rau sab nraud nyob rau hauv daim ntawv ntawm qhov deb-infrared rays nrog lub wavelength ntawm 5-14 microns, uas yuav luag zoo ib yam li tib neeg lub cev, ua "sib npaug-frequency resonance." Yog li ntawd, cov cua sov uas tsim los ntawm graphene tuaj yeem nkag mus tob rau hauv tib neeg lub cev thiab zoo dua absorbed!
