Nā hōʻike maʻalahi me nā fiber LED

ʻO nā filament LED, he mea i hana ʻia e ka Korean Institute of High Technology KAIST, he mea hiki ke lawelawe ma ke ʻano he fibrous, ulana ulana, a i ʻole ke kumu no ka hana ʻana i nā lole e hōʻike ana i nā kiʻi. ʻO nā prototypes o nā hōʻike maʻalahi i ʻike ʻia i kēia manawa ua hoʻokumu ʻia ma luna o kahi substrate paʻa. ʻOkoʻa loa ka hoʻoholo ʻana o ko Korea.

No ka hana ʻana i nā filament LED, hoʻopaʻa nā kānaka ʻepekema i kahi mea fibrous i kapa ʻia he polyethylene terephthalate i loko o kahi hopena o ka poly(3,4-dioxyethylenethiophene) me ka sulfonated polystyrene (PEDOT:PSS) a laila hoʻomaloʻo ma 130°C. A laila hoʻihoʻi lākou iā ia i loko o kahi mea i kapa ʻia polyphenylene vinyl, kahi polymer i hoʻohana ʻia i ke kūkulu ʻana i nā hōʻike OLED. Ma hope o ka hoʻomaloʻo hou ʻana, ua uhi ʻia nā fiber me kahi hui o ka lithium alumini fluoride (LiF/Al).

ʻO ka poʻe ʻepekema, e wehewehe ana i kā lākou ʻenehana i loko o ka puke moʻolelo kūikawā Advanced Electronic Materials, hoʻoikaika i kona pono i ka hoʻohālikelike ʻana me nā ʻano hana ʻē aʻe o ka hoʻopili ʻana i nā mea LED i nā hale cylindrical liʻiliʻi.
