Bo-rasaense ba tsoang Jeremane le Netherlands ba ntse ba etsa lipatlisiso tse ncha tse baballang tikolohoPLAlisebelisoa. Sepheo ke ho hlahisa lisebelisoa tse tšoarellang bakeng sa lisebelisoa tsa optical tse kang mabone a likoloi, lilense, li-plastiki tse khanyang kapa litataiso tse khanyang. Hajoale, lihlahisoa tsena hangata li entsoe ka polycarbonate kapa PMMA.
Bo-rasaense ba batla ho fumana polasetiki e thehiloeng ho bio ho etsa mabone a koloi. Hoa fumaneha hore acid ea polylactic ke lisebelisoa tse loketseng tsa mokhethoa.
Ka mokhoa ona, bo-rasaense ba rarolotse mathata a 'maloa a tobaneng le li-plastiki tsa setso: pele, ho lebisa tlhokomelo ea bona mehloling e tsosolositsoeng ho ka fokotsa ka katleho khatello e bakoang ke oli e sa hloekang indastering ea polasetiki; ea bobeli, e ka fokotsa ho ntšoa ha carbon dioxide; ea boraro, sena se Akarelletsa ho nahanela potoloho eohle ea bophelo ba lintho tse bonahalang.
Dr. Klaus Huber, moprofesa Univesithing ea Paderborn, Jeremane, o re: "Hase feela hore polylactic acid e na le melemo mabapi le ts'ebetso e tsitsitseng, e boetse e na le lisebelisoa tse ntle haholo tsa optical 'me e ka sebelisoa ka bongata bo bonahalang ba maqhubu a motlakase.
Hona joale, e 'ngoe ea mathata ao bo-rasaense ba a hlōlang ke ho sebelisoa ha polylactic acid masimong a amanang le LED. LED e tsejoa e le mohloli oa leseli o sebetsang hantle le o se nang tikoloho. "Haholo-holo, bophelo bo bolelele ba tšebeletso le mahlaseli a bonahalang, a kang lebone le leputsoa la mabone a LED, a beha litlhoko tse phahameng ho lisebelisoa tsa optical," ho hlalosa Huber. Ke ka lebaka lena ho tlamehang ho sebelisoa thepa e tšoarellang haholo. Bothata ke: PLA e fetoha e bonolo hoo e ka bang likhato tse 60. Leha ho le joalo, mabone a LED a ka fihla mocheso o fihlang ho likhato tse 80 ha a ntse a sebetsa.
Bothata bo bong bo phephetsang ke crystallization ea polylactic acid. Polylactic acid e etsa likristale ka likhato tse ka bang 60, tse fifatsang thepa. Bo-rasaense ba ne ba batla ho fumana mokhoa oa ho qoba crystallization ena; kapa ho etsa hore ts'ebetso ea crystallization e laolehe haholoanyane - e le hore boholo ba li-crystallites tse entsoeng bo ke ke ba ama leseli.
Ka laboratoring ea Paderborn, bo-rasaense ba ile ba qala ka ho etsa qeto ea hore na limolek'hule tsa polylactic acid e le ho fetola thepa ea eona, haholo-holo boemo ba eona ba ho qhibiliha le kristale. Huber o na le boikarabello ba ho batlisisa hore na li-additives, kapa matla a mahlaseli a kotsi, a ka ntlafatsang thepa ea thepa. "Re ile ra haha sistimi e nyenyane ea ho hasanya lebone ka ho khetheha bakeng sa sena ho ithuta ho thehoa ha kristale kapa mekhoa ea ho qhibiliha, mekhoa e nang le tšusumetso e kholo mosebetsing oa optical," ho boletse Huber.
Ho phaella tsebong ea saense le ea theknoloji, morero ona o ka fana ka melemo e mengata ea moruo ka mor'a hore e sebelisoe. Sehlopha se lebelletse ho fana ka leqephe la sona la pele la likarabo bofelong ba 2022.
