Iqembu lososayensi abavela eMassachusetts Institute of Technology liyaqhubeka nokusebenza ngempumelelo ngendlela ethakazelisa kakhulu. Eminyakeni eyisishiyagalolunye edlule, kumagazini i-Nature Communications, abasebenzi be-MIT , eyabika ngokuthuthukiswa kobuchwepheshe obuthakazelisayo bokuqondisa ama-molecule e-polyethylene. Esimeni sayo esivamile, i-polyethylene, njengamanye ama-polymer, ibukeka njengemfucumfucu yezigaxa eziningi ze-spaghetti ezinamathele ndawonye. Lokhu kwenza i-polymer ibe isivikelo sokushisa esihle kakhulu, futhi ososayensi bebelokhu befuna okuthile okungajwayelekile. Ukube nje besingenza i-polymer engakwazi ukushisa ukushisa okungaphezu kwensimbi! Futhi konke okudingekayo kulokhu ukuqondisa ama-molecule e-polymer ukuze akwazi ukudlulisa ukushisa ngama-monochannels ukusuka emthonjeni kuya endaweni yokulahla. Ukuhlola kube yimpumelelo. Ososayensi bakwazile ukwenza imicu ye-polyethylene ngayinye ene-conductivity enhle kakhulu yokushisa. Kodwa lokhu bekungenele ukwethulwa embonini.
Namuhla, iqembu elifanayo lososayensi abavela ku-MIT lishicilele umbiko omusha mayelana nama-polymers asebenzayo. Mningi umsebenzi owenziwe kule minyaka eyisishiyagalolunye edlule. Esikhundleni sokwenza imicu ngayinye, ososayensi isitshalo sokuhlola sokukhiqiza ifilimu ye-thermal conductive coating. Ngaphezu kwalokho, ukudala amafilimu abamba ukushisa, akusetshenziswanga izinto zokusetshenziswa eziyingqayizivele, njengeminyaka eyisishiyagalolunye edlule, kodwa i-polyethylene powder evamile yokuhweba embonini.
Esitshalweni sokuhlola, i-polyethylene powder iyancibilika oketshezini bese ukwakheka kufuthwe epuletini elipholile nge-nitrogen ewuketshezi. Ngemuva kwalokhu, i-workpiece iyashiswa futhi yelulwe emshinini wokugoqa esimweni sefilimu encane, ubukhulu befilimu yokugoqa. Izilinganiso zibonise ukuthi ifilimu ye-polyethylene ene-thermal conductive ekhiqizwa ngale ndlela ine-coefficient conductivity eshisayo engu-60 W / (m K). Ukuze uqhathanise, ngensimbi lesi sibalo singu-15 W / (m K), kanti epulasitiki evamile yi-0,1-0,5 W / (m K). Idayimane liqhosha ngokubamba kahle kwe-thermal - 2000 W/(m K), kodwa izinsimbi ezedlula zonke ku-thermal conductivity nakho kuhle.
I-polymer conductive thermally nayo inenani lezinye izinto ezibalulekile. Ngakho, ukushisa kuqhutshwa ngokuqinile ohlangothini olulodwa. Cabanga ngekhompyutha ephathekayo noma i-smartphone esusa ukushisa kumaphrosesa ngaphandle kwesistimu yokupholisa esebenzayo. Ezinye izinhlelo zokusebenza ezibalulekile zepulasitiki ehambisa ukushisa zifaka izimoto, amayunithi esiqandisi, nokunye. Ipulasitiki ayikwesabi ukugqwala, ayihambisi ugesi, ayisindi futhi ihlala isikhathi eside. Ukwethulwa kwezinto ezinjalo empilweni kungafaka umfutho ekuthuthukisweni kwezimboni emikhakheni eminingi. Ngifisa sengathi angizange ngilinde eminye iminyaka eyisishiyagalolunye kulolu suku oluqhakazile.
