Ososayensi baseJalimane naseNetherlands benza ucwaningo olusha oluhambisana nemveloI-PLAizinto zokwakha.Inhloso ukuthuthukisa izinto ezisimeme zezinhlelo zokusebenza ze-optical ezifana nezibani zangaphambili zezimoto, amalensi, amapulasitiki akhanyayo noma iziqondiso ezikhanyayo.Okwamanje, le mikhiqizo ngokuvamile yenziwe nge-polycarbonate noma i-PMMA.
Ososayensi bafuna ukuthola ipulasitiki esekwe ku-bio yokwenza izibani zemoto.Kuvela ukuthi i-polylactic acid iyinto efanelekile yekhandidethi.
Ngale ndlela, ososayensi baye baxazulula izinkinga eziningana ezibhekene namapulasitiki endabuko: okokuqala, ukunaka izinsiza ezivuselelekayo kunganciphisa ngokuphumelelayo ingcindezi ebangelwa uwoyela ongahluziwe embonini yepulasitiki;okwesibili, kunganciphisa ukukhishwa kwesikhutha;okwesithathu, lokhu Kubandakanya ukucatshangelwa kwawo wonke umjikelezo wempilo yezinto ezibonakalayo.
"Akukhona nje ukuthi i-polylactic acid inezinzuzo mayelana nokusimama, futhi inezici ezinhle kakhulu ze-optical futhi ingasetshenziswa ku-spectrum ebonakalayo yamagagasi kagesi," kusho uDkt. Klaus Huber, uprofesa eNyuvesi yasePaderborn eJalimane.
Njengamanje, obunye bobunzima ososayensi ababunqobayo wukusetshenziswa kwe-polylactic acid emikhakheni ehlobene ne-LED.I-LED yaziwa njengomthombo wokukhanya osebenzayo futhi ovumela imvelo."Ikakhulukazi, impilo yesevisi ende kakhulu kanye nemisebe ebonakalayo, njengokukhanya okuluhlaza okwesibhakabhaka kwezibani ze-LED, kubeka izidingo eziphezulu ezintweni ezibonakalayo," kuchaza uHuber.Yingakho kufanele kusetshenziswe izinto ezihlala isikhathi eside.Inkinga iwukuthi: I-PLA ithambile cishe ngama-degree angama-60.Kodwa-ke, izibani ze-LED zingafinyelela amazinga okushisa afinyelele kuma-degree angu-80 ngenkathi isebenza.
Obunye ubunzima obuyinselele yi-crystallization ye-polylactic acid.I-Polylactic acid yakha amakristalu cishe ngama-degree angama-60, afiphalisa impahla.Ososayensi bafuna ukuthola indlela yokugwema lokhu crystallization;noma ukwenza inqubo ye-crystallization ilawuleke kakhulu - ukuze ubukhulu bamakristalu abunjiwe abuthinti ukukhanya.
Elabhorethri yasePaderborn, ososayensi baqale banquma izakhiwo zamangqamuzana e-polylactic acid ukuze baguqule izakhiwo zezinto, ikakhulukazi isimo sayo sokuncibilika kanye nokucwebezela.U-Huber unesibopho sokuphenya ukuthi izithasiselo, noma amandla emisebe, zingathuthukisa kangakanani izakhiwo zezinto."Sakha uhlelo lokusabalalisa ukukhanya kwe-angle encane ngokukhethekile kulokhu ukuze sifunde ukwakheka kwekristalu noma izinqubo zokuncibilika, izinqubo ezinomthelela omkhulu ekusebenzeni kwe-optical," kusho u-Huber.
Ngaphezu kolwazi lwesayensi nobuchwepheshe, iphrojekthi ingaletha izinzuzo ezibalulekile zezomnotho ngemuva kokuqaliswa.Ithimba lilindele ukunikezela ngephepha lalo lokuqala lempendulo ekupheleni kuka-2022.
