Liphatlalatso tsa likaroloana tsa polymer mokhahlelong oa mokelikeli (latexes) li na le ts'ebeliso e mengata ea bohlokoa ho theknoloji ea ho roala, litšoantšo tsa bongaka, le baeloji ea lisele.Sehlopha sa Mafora sa bafuputsi se se se thehile mokhoa, se tlalehiloeng korantengKhatiso ea Machaba ea Angewandte Chemie, ho hlahisa li-dispersions tse tsitsitseng tsa polystyrene tse nang le boholo bo boholo bo sa tloaelehang le bo lekanang.Kabo ea boholo bo moqotetsane bo bohlokoa ho litheknoloji tse ngata tse tsoetseng pele, empa pele ho ne ho le thata ho hlahisa photochemically.
Polystyrene, e atisang ho sebelisoa ho etsa foam e atolositsoeng, e boetse e loketse tlhahiso ea li-latexes, moo likaroloana tse nyenyane tsa polystyrene li emisitsoeng.Li sebelisoa ha ho etsoa lipente le lipente hape bakeng sa merero ea ho lekanya ho microscopy lesetšoantšo sa bongakale lipatlisiso tsa baeloji ea lisele.Hangata li hlahisoa ke thermally kapa redox-inducedpolymerizationka hare ho tharollo.
Ho fumana taolo ea kantle ho ts'ebetso, lihlopha tsa Muriel Lansalot, Emmanuel Lacôte, le Elodie Bourgeat-Lami ho Université Lyon 1, France, le basebetsi mmoho, ba fetohetse lits'ebetsong tse tsamaisoang ke leseli."Polymerization e tsamaisoang ke leseli e tiisa taolo ea nakoana, hobane polymerization e tsoela pele feela ka pel'a leseli, athe mekhoa ea mocheso e ka qalisoa empa e sa emisoe hang ha e ntse e tsoela pele," Lacôte o re.
Leha ho se ho thehiloe lits'ebetso tsa UV- kapa tse putsoa-based photopolymerization, li na le meeli.Mahlaseli a maqhubu a makhutšoane a hasane ha aboholo ba karoloanae ba haufi le bolelele ba maqhubu a mahlaseli, e leng ho etsa hore latexes e nang le likaroloana tse kholo ho feta maqhubu a kenang ho thata ho hlahisa.Ho feta moo, leseli la UV le nka matla haholo, re sa bue ka kotsi ho batho ba sebetsang le lona.
Ka hona, bafuputsi ba ile ba theha mokhoa o motle oa ho qala lik'hemik'hale o arabelang ho khanya e tloaelehileng ea LED sebakeng se bonahalang.Sistimi ena ea polymerization, e thehiloeng ho dae ea acridine, stabilizers, le motsoako oa borane, e bile eona ea pele ea ho hlola "siling ea nanometer tse 300," moeli oa boholo ba UV le polymerization e tsamaisoang ke khanya e putsoa sebakeng se qhalakaneng.Ka lebaka leo, ka lekhetlo la pele, sehlopha se ile sa khona ho sebelisa leseli ho hlahisa li-latex tsa polystyrene tse nang le likaroloana tse kholo ho feta micrometer e le 'ngoe le li-diameter tse lekanang haholo.
Sehlopha se fana ka maikutlo a likopo ho feta moopolystyrene.Lacôte o re: "Mokhoa ona o ne o ka sebelisoa libakeng tsohle tseo ho tsona ho sebelisoang li-latex, tse kang lifilimi, li-coatings, litšehetso bakeng sa ho hlahloba mafu le tse ling.Ho feta moo, likaroloana tsa polymer li ka fetoloa kalidae tsa fluorescent, lihlopha tsa makenete, kapa lisebelisoa tse ling tse molemo bakeng sa lits'ebetso tsa tlhahlobo le litšoantšo.Sehlopha se re mefuta e mengata ea boholo ba likaroloana tse pakeng tsa nano le li-scale tse nyane li ka fihlelleha "ka ho hlophisa maemo a pele.
