Izazinzulu ezivela eJamani naseNetherlands zenza uphando olutsha oluhambelana nokusingqongileyoI-PLAizixhobo.Injongo kukuphuhlisa izinto ezizinzileyo zezicelo ze-optical ezifana nezibane zemoto, iilensi, iiplastiki ezikhanyayo okanye izikhokelo ezikhanyayo.Okwangoku, ezi mveliso zenziwe ngokubanzi nge-polycarbonate okanye i-PMMA.
Izazinzulu zifuna ukufumana iplastiki esekwe kwibhayoloji ukwenza izibane zemoto.Kuvela ukuba i-polylactic acid yinto efanelekileyo yomviwa.
Ngale ndlela, izazinzulu ziye zasombulula iingxaki ezininzi ezijongene neeplastiki zemveli: okokuqala, ukuguqula ingqalelo kwimithombo ehlaziyiweyo kunokunciphisa ngokufanelekileyo uxinzelelo olubangelwa yi-oyile ekrwada kwishishini leplastiki;okwesibini, inokunciphisa ukukhutshwa kwekharbon diokside;okwesithathu, oku Kubandakanya ukuqwalaselwa kwawo wonke umjikelo wobomi bezinto eziphathekayo.
"Akukhona nje kuphela ukuba i-polylactic acid ineenzuzo ngokuzinza, nayo ineempawu ezintle kakhulu ze-optical kwaye ingasetyenziselwa kwi-spectrum ebonakalayo yamaza e-electromagnetic," kusho uDkt. Klaus Huber, uprofesa kwiYunivesithi yasePaderborn eJamani.
Okwangoku, enye yobunzima oboyisayo izazinzulu kukusetyenziswa kwe-polylactic acid kwiinkalo ezinxulumene ne-LED.I-LED yaziwa njengomthombo wokukhanya osebenzayo kunye nokusingqongileyo."Ngokukodwa, ubomi benkonzo ende kakhulu kunye nemitha ebonakalayo, njengokukhanya okuluhlaza kwezibane ze-LED, kubeka iimfuno eziphezulu kwizinto ezibonakalayo," kuchaza uHuber.Yiyo loo nto kufuneka kusetyenziswe imathiriyeli eyomelele kakhulu.Ingxaki yile: I-PLA ithambile malunga ne-60 degrees.Nangona kunjalo, izibane ze-LED zinokufikelela kumaqondo obushushu ukuya kuma-80 degrees ngelixa usebenza.
Obunye ubunzima obungumngeni yikristale ye-polylactic acid.Iasidi yePolylactic yenza iikristale malunga needigri ezingama-60, eziphazamisa izinto.Izazinzulu zazifuna ukufumana indlela yokuphepha le crystallization;okanye ukwenza inkqubo ye-crystallization ilawuleke ngakumbi - ukwenzela ukuba ubukhulu beekristali ezibunjiweyo aziyi kuchaphazela ukukhanya.
Kwilabhoratri yasePaderborn, izazinzulu zaqala zamisela iipropathi zemolekyuli ze-polylactic acid ukwenzela ukuguqula izinto eziphathekayo, ngokukodwa ukunyibilika kwayo kunye ne-crystallization.U-Huber unoxanduva lokuphanda ubungakanani bezongezo, okanye amandla emitha, anokuphucula iipropathi zezinto."Sakha inkqubo yokusabalalisa ukukhanya kwe-angle encinci ngokukodwa kule nto yokufunda ukubunjwa kwe-crystal okanye iinkqubo zokunyibilika, iinkqubo ezinempembelelo enkulu kumsebenzi we-optical," kusho u-Huber.
Ukongeza kulwazi lwezesayensi kunye nobuchwepheshe, iprojekthi inokunikezela ngeenzuzo ezibalulekileyo zezoqoqosho emva kokuphunyezwa.Iqela lilindele ukunikezela ngephepha lalo lokuqala leempendulo ekupheleni kuka-2022.
