Skupina znanstvenikov z Massachusetts Institute of Technology \u0161e naprej uspe\u0161no deluje na zelo zanimivem podro\u010dju. Pred devetimi leti so zaposleni na MIT v reviji Nature Communications <\/a>objavili poro\u010dilo<\/a><\/noindex>, v katerem so poro\u010dali o razvoju zanimive tehnologije za ravnanje molekul polietilena. V obi\u010dajnem stanju je polietilen, kot drugi polimeri, podoben ka\u0161i iz \u0161tevilnih gru\u010di zlepljenih \u0161pagetov. To naredi polimer izvrsten toplotni izolator, znanstveniki pa so si vedno \u017eeleli kaj nenavadnega. Kako bi bilo lepo ustvariti polimer, ki bi prena\u0161al toploto tako dobro kot kovine! In za to je treba le to \u2015 ravnati molekule polimera, da bi lahko prek monokanala prena\u0161ale toploto od vira do mesta razpr\u0161itve. Eksperiment je uspel. Znanstveniki so uspeli ustvariti posamezna vlakna polietilena z odli\u010dno toplotno prevodnostjo. A za industrijsko uporabo to ni bilo dovolj.<\/p>\n

\"Radiatorji<\/p>\n

Danes je ista skupina znanstvenikov z MIT objavila nov poro\u010dilo o toplotno prevodnih polimerih. V preteklih devetih letih je bilo opravljenega veliko dela. Namesto izdelave posameznih vlaken so znanstveniki <\/a>razvili in ustvarili<\/a><\/noindex> poskusno napravo za izdelavo filmske toplotno prevodne prevleke. Poleg tega je za ustvarjanje toplotno prevodnih filmov bilo uporabljeno ne edinstveno, kot pred devetimi leti, surovino, temve\u010d obi\u010dajen komercialni pra\u0161kasti polietilen za industrijo.<\/p>\n

V izku\u0161eni namestitvi se polietilenski prah raztopi v teko\u010dini, nato pa se zmes razpr\u0161i na plo\u0161\u010do, ohlajeno z teko\u010dim du\u0161ikom. Po tem se obdelovanec segreje in raztegne na valjarju do stanja tanke folije, debeline kot embala\u017eni material. Meritve so pokazale, da tako izdelana toplotno prevodna polietilenska folija dosega toplotno prevodnost 60 W\/(m\u00b7K). Za primerjavo, pri jeklu zna\u0161a ta kazalnik 15 W\/(m\u00b7K), obi\u010dajni plastiki pa 0,1\u20130,5 W\/(m\u00b7K). Najbolj\u0161o toplotno prevodnost ima diamant \u2013 2000 W\/(m\u00b7K), toda prese\u010di kovine po toplotni prevodnosti je prav tako dobro.<\/p>\n

<\/center><\/p>\n

Toplotno prevodni polimer ima tudi vrsto drugih pomembnih lastnosti. Toplota se prena\u0161a natan\u010dno v eni smeri. Predstavljajte si prenosni ra\u010dunalnik ali pametni telefon, ki od odvaja toploto z procesorjev brez aktivnega sistema hlajenja. Druge pomembne aplikacije toplotno prevodnega plastike bi lahko bile v avtomobilih, hladilnih sistemih in drugem. Plastika se ne boji korozije, ne prevaja elektrike, je lahka in trdna. Uvedba tovrstnih materialov v vsakdanjost bi lahko spro\u017eila razvoj industrije v \u0161tevilnih panogah. Upamo, da ne bomo \u010dakali \u0161e devet let do tega svetlega dne.<\/p>\n
