Thaum Lub Rau Hli 8, 2023, Xib Fwb Tang Ruikang thiab tus kws tshawb fawb Liu Zhaoming los ntawm Lub Tsev Haujlwm Saib Xyuas Chemistry ntawm Zhejiang University tau tshaj tawm txog kev tsim cov "yas yas ceramic elastic". Qhov no yog cov khoom siv tshiab uas sib xyaw ua ke qhov nyuaj thiab mos, nrog rau qhov nyuaj zoo li ceramic, elastic zoo li roj hmab, thiab plasticity zoo li yas.
Cov khoom no puas yog yas pob tshab los yog ceramic? Nws yog cov yas ceramic uas pab pawg Zhejiang University tau npaj.
"Elastic ceramic plastics" yog thawj zaug uas tau paub txog kev sib xyaw ua ke ntawm cov organic compounds thiab inorganic Ionic compound ntawm qib molecular, kom tau txais cov khoom tshiab nrog cov khoom sib txawv ntawm cov khoom siv yav dhau los. Hauv kev paub txog ib txwm muaj, cov txheej txheem npaj cov khoom siv hauv thaj chaw ntawm Inorganic chemistry thiab Polymer chemistry yog txawv kiag li. Nws tau tshaj tawm tias "elastic ceramic plastic" polymerized los ntawm hybrid molecules hauv chav kuaj yog lub pob me me daj zoo li lub cev. Hauv nws cov molecules, lub inorganic ionic bond network thiab cov organic Covalent bond network yog intertwined thiab interspersed, uas tsis tsuas yog muaj cov khoom ntawm cov khoom inorganic, tab sis kuj khaws cov yam ntxwv ntawm cov khoom organic, thiab muaj qee qhov nyuaj thiab elasticity. Thaum muaj qee lub zog sab nraud siv, lub cev pob txha inorganic tuaj yeem muab qhov nyuaj thiab lub zog; Thaum lub zog sab nraud loj thiab elastic deformation tshwm sim, tag nrho lub cev pob txha deforms, tsim cov nyhuv buffering; Tom qab tshem tawm cov zog sab nraud, lub cev pob txha organic exerts ib qho rebound effect, rov qab lub network rau nws lub xeev qub. Yav dhau los, organic-inorganic fusion yog ib qho yooj yim superposition, ib yam li nchuav inorganic hmoov rau hauv cov organic framework thiab do kom sib npaug. Yog koj faib ib txheej zuj zus, theem molecular tseem yog "koj li koj li, kuv li kuv li", tsuas yog qhov sib xyaw ntawm ob qho no, "qhov kev sim no tsim cov molecule tshiab uas tsis yog yav dhau los, tau txais cov qauv tshiab, thiab rhuav tshem qhov thaiv ntawm cov organic compounds thiab inorganic Ionic compound ntawm qhov ntsuas molecular."
Cov kws tshawb fawb ntawm Zhejiang University tau piv qhov kev ua tau zoo ntawm cov khoom siv tshiab no nrog rau cov khoom siv ceramics, roj hmab, yas, hlau, thiab lwm yam. Nws tau ua tiav cov qhab nia siab hauv qhov nyuaj, rov qab los, lub zog, kev hloov pauv, thiab kev ua haujlwm tau zoo. Nws tsis tsuas yog muaj qhov nyuaj ntawm marble xwb, tab sis kuj muaj qhov elasticity ntawm roj hmab thiab qhov plasticity ntawm yas. Kuj tseem muaj cov yam ntxwv uas cov yas ib txwm tsis muaj: lawv tsis mos tom qab cua sov.
