Boka revasayendisiti kubva kuMassachusetts Institute of Technology rinoramba richibudirira kushanda munzira inonakidza kwazvo. Makore mapfumbamwe apfuura, mujenari Nature Communications, vashandi veMIT , iyo yakashuma pamusoro pekugadzirwa kwekombiyuta inofadza yekururamisa polyethylene molecules. Mumamiriro ayo akajairika, polyethylene, semamwe mapolymer, inoita senge tsvina yemapundu mazhinji espaghetti akabatana. Izvi zvinoita kuti iyo polima ive yakanakisa kupisa insulator, uye masayendisiti agara achida chimwe chinhu chisina kujairika. Dai chete taigona kugadzira polima yaigona kuitisa kupisa kusina kuipa kupfuura simbi! Uye zvese zvinodikanwa pane izvi kutwasanudza mamorekuru epolymer kuitira kuti akwanise kutamisa kupisa kuburikidza nemamonochannels kubva kutsime kuenda kunzvimbo yekurasa. Kuedza kwakabudirira. Masayendisiti akakwanisa kugadzira ega ega polyethylene fiber ine yakanakisa yekupisa conductivity. Asi izvi zvakanga zvisina kukwana kuti tisungwe mumaindasitiri.
Nhasi, iro boka rimwe chete resainzi kubva kuMIT rakaburitsa chirevo chitsva pane thermally conductive polymers. Basa rakawanda rakaitwa mumakore mapfumbamwe apfuura. Panzvimbo pekugadzira shinda dzega, masayendisiti pilot plant yekugadzira thermally conductive film coating. Uyezve, kugadzira mafirimu ekupisa-kupisa, kwete yakasarudzika zvigadzirwa zvakashandiswa, senge makore mapfumbamwe apfuura, asi zvakajairika zvekutengesa polyethylene poda yeindasitiri.
Muchirimwa chekutyaira, polyethylene poda inonyungudutswa mumvura uye ipapo kuumbwa kunopfapfaidzwa mundiro yakanyoroveswa nenitrogen yemvura. Mushure meizvi, workpiece inopisa uye yakatambanudzwa pamushini unoputika kusvika kune imwe nyika yefirimu yakaonda, iyo yakakura yefirimu yekuputira. Zviyero zvakaratidza kuti thermally conductive polyethylene firimu inogadzirwa nenzira iyi ine thermal conductivity coefficient ye60 W/(m K). Kuenzanisa, yesimbi iyi nhamba i15 W / (m K), uye yepurasitiki yakajairika ndeye 0,1-0,5 W / (m K). Dhaimondi rinozvikudza yakanakisa yekupisa conductivity - 2000 W/(m K), asi kupfuura simbi mukupisa conductivity yakanaka zvakare.
Iyo thermally conductive polymer zvakare ine akati wandei mamwe akakosha hunhu. Saka, kupisa kunoitwa zvakasimba mune imwe nzira. Fungidzira Laptop kana smartphone inobvisa kupisa kubva kune processors isina inoshanda yekutonhora system. Mamwe maapplication akakosha epurasitiki inoitisa thermally anosanganisira mota, mafiriji zvikamu, nezvimwe. Plastiki haityi kuparara, haifambisi magetsi, inoreruka uye inogara kwenguva refu. Kuunzwa kwezvinhu zvakadaro muhupenyu kunogona kupa kukurudzira mukusimudzira indasitiri muzvikamu zvakawanda. Ndinoshuva kuti dai ndisina kumirira mamwe makore mapfumbamwe kune iri zuva rakajeka.
