Kiʻi kiʻi: ACS Applied Materials and Interfaces
Ua hana nā ʻenekinia ma ke Kulanui o Massachusetts Amherst i kahilole lolee mālama ana iā ʻoe me ka hoʻohana ʻana i ke kukui o loko. ʻO ka ʻenehana ka hopena o kahi ʻimi 80-makahiki e synthesize textiles e pili ana i ka polar bearhuluhulu. Ua paʻi ʻia ka noiʻi ma ka puke pai ACS Applied Materials and Interfaces a ua hoʻomohala ʻia i kēia manawa i huahana kūʻai.
Noho nā bea polar i kekahi o nā kaiapuni ʻoi loa ma ka honua a ʻike ʻole ʻia e nā mahana Arctic ma lalo o 45 degere Celsius. ʻOiai he nui nā ʻano hoʻololi ʻana o ka bea e hiki ai iā lākou ke ulu i ka wā e hāʻule ana ka mahana, ua nānā nui nā ʻepekema i ka hiki ke hoʻololi ʻia o ko lākou hulu mai ka makahiki 1940. Pehea ka bea polarhuluhulue mahana?
Nui nā holoholona polar e hoʻohana ikaika ana i ka lā e mālama ai i ka mahana o ko lākou kino, a ʻo ka hulu bea polar kekahi laʻana kaulana. No nā makahiki he nui, ua ʻike ka poʻe ʻepekema ʻo ka ʻāpana huna o nā bea ko lākou hulu keʻokeʻo. Manaʻo ʻia ʻoi aku ka maikaʻi o ka hoʻomoʻa ʻana o ka hulu ʻeleʻele i ka wela, akā ʻoi aku ka maikaʻi o ka hulu bea polar i ka hoʻoili ʻana i ka pāhawewe lā i ka ʻili.
polar bearhuluhuluHe fiber maoli nō ia e alakaʻi i ka lā i ka ʻili o ka bea, nāna e hoʻomoe i ka mālamalama a hoʻomehana i ka bea. A ʻo kahuluhulumaikaʻi nō hoʻi i ka pale ʻana i ka ʻili mehana mai ka hāʻawi ʻana i kēlā wela paʻakikī. Ke ʻā mai ka lā, ua like ia me ka loaʻa ʻana o kahi pākeʻe mānoanoa e hoʻomaʻamaʻa iā ʻoe iho a laila hoʻopaʻa i ka mehana i kou ʻili.
Ua noʻonoʻo ka hui noiʻi i kahi lole ʻelua ʻāpana nona ka papa luna i loaʻa i nā kaula e like me ka polar bearhuluhulu, e alakaʻi i ke kukui ʻike ʻia i ka papa haʻahaʻa, i hana ʻia me ka nylon a uhi ʻia me kahi mea ʻeleʻele i kapa ʻia ʻo PEDOT. Hana ʻo PEDOT e like me ka ʻili o ka bea polar e mālama i ka mahana.
He 30% ʻoi aku ka māmā o ka ʻaʻahu i hana ʻia mai kēia mea ma mua o ka ʻaʻahu pulupulu hoʻokahi, a ʻoi aku ka maikaʻi o kāna hana ʻana i ka māmā a me ka wela no ka hoʻomehana ʻana i ke kino me ka hoʻohana ʻana i nā kukui o loko. Ma ka hoʻopaʻa ʻana i nā kumuwaiwai ikehu a puni ke kino e hana i kahi "kikowaena pilikino", ʻoi aku ka paʻa o kēia ʻano ma mua o nā ʻano hana hoʻomehana a me ka hoʻomehana ʻana.
