4,4′-DIAMINOBIPHENYL-2,2′-DICARBOXYLIC ACID cas:17557-76-5

ʻO ka wehewehe pōkole:

ʻO 4,4′-diaminobiphenyl-2,2′-dicarboxylic acid, i ʻike ʻia ʻo DABDA, he mea hoʻohui kemika me ka molecular formula C16H14N2O4.He pauka keʻokeʻo keʻokeʻo i hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ethanol, acetone, a me ka methanol.Loaʻa iā DABDA nā waiwai kemika kūʻokoʻa e kūpono ai i nā noi he nui.

Loaʻa ka hoʻohana nui ʻana o kēia pūhui kemika ma ke kahua o ka noiʻi polymer a me ka hoʻomohala ʻana.Ma muli o kona kūpaʻa wela kiʻekiʻe a me nā waiwai mechanical maikaʻi, hoʻohana mau ʻia ʻo DABDA ma ke ʻano he hale kūkulu hale i ka synthesis o nā polymers kiʻekiʻe.Loaʻa i kēia mau polymers ka nui o nā noi, me nā uhi, nā mea hoʻopili, a me nā insulators uila.

Eia kekahi, hōʻike ʻo DABDA i nā waiwai electrochemical maikaʻi loa, e lilo ia i moho kūpono no ka hoʻomohala ʻana i nā mea hana electrochemical kiʻekiʻe.Hoʻohana nui ʻia ia i ka hana ʻana i nā electrodes no nā supercapacitors a me nā pā lithium-ion.Me kona conductivity kūikawā a me ka paʻa, hāʻawi ʻo DABDA i ka hana holoʻokoʻa a me ke ola o kēia mau ʻōnaehana mālama ikehu.

E hoʻouna i ka leka uila iā mākou

Huahana Huahana

Hana ʻia kā mākou 4,4′-diaminobiphenyl-2,2′-dicarboxylic acid e hōʻoia i ka pae kiʻekiʻe o ka maʻemaʻe a me ka maikaʻi.Loaʻa kēlā me kēia pūʻulu i ka hoʻāʻo a me ka nānā ʻana e kūlike me nā kūlana honua.Haʻaheo mākou i ka hāʻawi ʻana i kahi huahana ma mua o ka manaʻo o ka mea kūʻai aku a hoʻokō i nā koi o nā ʻoihana like ʻole.

Nā ʻōlelo aʻoaʻo palekana a me ka lawelawe ʻana:

- Hōʻalo i ka pili ʻana i ka ʻili a me ka inhalation o ka lepo a i ʻole ka mahu.Pono e hoʻohana ʻia nā mea pale pono i ka wā e lawelawe ai i kēia pūhui.

- E mālama ma kahi maloʻo maloʻo ma kahi mamao mai ka lā pololei a me nā mea like ʻole.

- E hahai i nā kaʻina hana hoʻolei kūpono e like me nā kānāwai kūloko.
