Musi waChikumi 8, 2023, Muzvinafundo Tang Ruikang nemuongorori Liu Zhaoming kubva kuDhipatimendi reChemistry paZhejiang University vakazivisa kuumbwa kwe "elastic ceramic plastic". Ichi chinhu chitsva chinosanganisa kuoma uye kupfava, neceramic senge kuoma, rabha senge elasticity, uye plastiki sepurasitiki.
Ichi chinhu chakajeka chepurasitiki kana ceramic? Iyo elastic ceramic plastiki yakagadzirwa nechikwata cheZhejiang University.
"Elastic ceramic mapurasitiki" inguva yekutanga kuona musanganiswa weorganic compounds uye inorganic Ionic komboni pachikamu chemolecular, kuitira kuti uwane zvinhu zvitsva zvine zvimiro zvakasiyana kubva kune zvakapfuura. Mukuziva kwechinyakare, nzira dzekugadzirira dzezvinhu mumunda weInorganic chemistry uye Polymer chemistry dzakasiyana zvachose. Zvinonzi "elastic ceramic plastic" polymerized nema hybrid mamorekuru murabhoritari ibhatani diki reyero semuviri. Mumamorekuru ayo, iyo inorganic ionic bond network uye iyo organic Covalent bond network yakabatana uye yakapindirana, iyo isingangove ine zvimiro zvezvinhu zvemukati, asi zvakare inochengeta maitiro eiyo organic zvinhu, uye ine imwe kuoma uye elasticity. Kana imwe simba rekunze rinoshandiswa, inorganic skeleton inogona kupa kuoma uye simba; Kana simba rekunze rakakura uye elastic deformation inoitika, skeleton yese inoshanduka, ichigadzira buffering effect; Mushure mekubvisa masimba ekunze, iyo organic skeleton inoita rebound mhedzisiro, kudzorera network kune yayo yekutanga. Kare, organic-inorganic fusion yaive yakapusa superposition, sekudira inorganic poda muorganic framework uye kubvongodza zvakaenzana. Kana iwe ukagovanisa layer ne layer, iyo molecular level ichiri "iwe ndewako, ini ndewangu", musanganiswa wezviviri izvi, "kuedza uku kwakaburitsa mamorekuru matsva akange asiri kare, akawana chimiro chitsva, uye akatyora chipingamupinyi pakati pemakemikari emakemikari uye inorganic Ionic komboni pachiyero chemolecular."
Zhejiang University masayendisiti akaenzanisa mashandiro echinhu chitsva ichi nekeramics, rabha, mapurasitiki, simbi, nezvimwe. Iyo yakawana zvibodzwa zvakakwirira mukuoma, rebound, simba, deformation, uye processability. Haisi chete ine marble level kuoma, asiwo ine elasticity yerabha uye mapurasitiki epurasitiki. Kune zvakare maitiro ayo echinyakare mapurasitiki haana: haapfave mushure mekupisa.
