Ma Iune 8, 2023, ua hoʻolaha ʻo Polofesa Tang Ruikang a me ka mea noiʻi ʻo Liu Zhaoming mai ke Keʻena ʻOihana Kimia ma Zhejiang University i ka synthesis o "elastic ceramic plastic". He mea hou kēia e hoʻohui i ka paʻakikī a me ka palupalu, me ka seramika e like me ka paʻakikī, ka ʻōpala e like me ka elasticity, a me ka plastic like plasticity.
ʻO kēia mea alohilohi a i ʻole keramic? He plastic ceramic elastic i hoʻomākaukau ʻia e ka hui ʻo Zhejiang University.
ʻO "Elastic ceramic plastics" ka manawa mua e ʻike ai i ka hui pū ʻana o nā pūhui organik a me ka hui Ionic inorganic i ka pae mole, i loaʻa ai nā mea hou me nā waiwai ʻokoʻa mai nā mea mua. I ka ʻike kuʻuna, ʻokoʻa loa nā ʻano hoʻomākaukau o nā mea i loko o ke kahua o Inorganic chemistry a me Polymer chemistry. Ua hōʻike ʻia ʻo ka "elastic ceramic plastic" i polymerized e nā molekele hybrid i loko o ke keʻena hana he pihi melemele liʻiliʻi e like me ke kino. I loko o kāna mau mole, ua hoʻopili ʻia a hoʻopaʻa ʻia ka pūnaewele hoʻopaʻa ionic inorganic a me ka pūnaewele Covalent bond, ʻaʻole wale nā mea waiwai o nā mea inorganic, akā paʻa nō hoʻi nā ʻano o nā mea kūlohelohe, a loaʻa kekahi paʻakikī a me ka elasticity. Ke hoʻohana ʻia kekahi ikaika o waho, hiki i ka iwi kino ke hāʻawi i ka paʻakikī a me ka ikaika; I ka nui o ka ikaika o waho a hiki mai ka elastic deformation, hoʻololi ka iwi holoʻokoʻa, e hana ana i ka hopena buffering; Ma hope o ka hoʻoneʻe ʻana i nā mana o waho, hoʻokō ka ʻiʻo organik i ka hopena rebound, e hoʻihoʻi i ka pūnaewele i kona kūlana mua. I ka wā ma mua, he mea maʻalahi ka hui ʻana i ka organik-inorganic, e like me ka ninini ʻana i ka pauka inorganic i loko o ke ʻano organik a hoʻoulu like. Inā ʻoe e hoʻokaʻawale i ka papa ma ka papa, ʻo ka pae molekala "nou ʻoe, noʻu wau", ʻo ka hui pū ʻana o nā mea ʻelua, "ua hana kēia hoʻokolohua i nā molekala hou ʻaʻole i ka wā ma mua, loaʻa kahi hale hou, a ua uhaki i ka pale ma waena o nā mea hoʻohuihui a me ka pūhui Ionic inorganic ma ka pālākiō mole.
Ua hoʻohālikelike ka poʻe ʻepekema ʻo Zhejiang University i ka hana ʻana o kēia mea hou me nā ceramics, rubber, plastics, metals, a me nā mea ʻē aʻe. Ua loaʻa i nā helu kiʻekiʻe ma ka paʻakikī, rebound, ikaika, deformation, a me ka processability. ʻAʻole ʻo ia wale nō ka paʻakikī o ka pae marble, akā loaʻa nō hoʻi ka elasticity o ka lāʻau a me ka plasticity o nā plastic. Aia kekahi mau hiʻohiʻona i loaʻa ʻole i ka plastic plastic: ʻaʻole lākou e palupalu ma hope o ka hoʻomehana ʻana.
Ka manawa hoʻouna: Iulai-25-2023
