Musi wa8 Chikumi 2023, Purofesa Tang Ruikang nemuongorori Liu Zhaoming wekuDhipatimendi reChemistry paYunivhesiti yeZhejiang vakazivisa kugadzirwa kwe "purasitiki yeceramic yakasununguka". Ichi chinhu chitsva chinosanganisa kuomarara nekupfava, nekuomarara kwakaita seceramic, kusimba kwakaita serabha, uye purasitiki yakaita seplasticity.
Iyi ipurasitiki inoonekera here kana kuti ceramic? Ipurasitiki yeceramic inonamira yakagadzirwa nechikwata cheZhejiang University.
"Elastic ceramic plastiki" ndiyo nguva yekutanga kuona musanganiswa wemakemikari eorganic neIonic compound isingasanganisike padanho remamorekuru, kuitira kuti pave nezvinhu zvitsva zvine hunhu hwakasiyana nezvinhu zvekare. Mukuziva kwechinyakare, nzira dzekugadzirira zvinhu mumunda weInorganic chemistry nePolymer chemistry dzakasiyana zvachose. Zvinonzi "elastic ceramic plastic" yakagadziriswa nemahybrid molecules murabhoritari idiki diki rakaita sebhatani reyero. Mumamorekuru ayo, inorganic ionic bond network neorganic Covalent bond network zvakabatana uye zvakabatana, izvo zvisingangove nehunhu hwezvinhu zvisingasanganisike chete, asiwo zvinochengetedza hunhu hwezvinhu zvisingasanganisike, uye zvine kuomarara uye kusimba. Kana simba rekunze rakati rikashandiswa, inorganic skeleton inogona kupa kuomarara nesimba; Kana simba rekunze rakakura uye elastic deformation ikaitika, skeleton yese inoshanduka, ichigadzira buffering effect; Mushure mekubvisa masimba ekunze, organic skeleton inoita rebound effect, ichidzorera network kumamiriro ayo epakutanga. Kare, organic-inorganic fusion yaive superposition yakapfava, sekudurura inorganic powder muorganic framework uye kusanganisa zvakaenzana. Kana ukapatsanura rukoko nerukoko, mwero wemamorekuru uchiri "uri wako, ndiri wangu", kungova musanganiswa wezviviri izvi, "kuyedza uku kwakagadzira mamorekuru matsva akanga asipo kare, kwakawana chimiro chitsva, uye kwakaputsa chipingamupinyi chiri pakati pemakemikari eorganic neIonic compound isina kugadzirwa pachiyero chemamorekuru."
Masayendisiti eZhejiang University akaenzanisa mashandiro echinhu chitsva ichi neceramics, rabha, mapurasitiki, simbi, nezvimwewo. Chakawana mamakisi akakwirira mukuomarara, kudzokororwa, simba, kushanduka, uye kugona kushandiswa. Hachingori nekuomarara kwemarble chete, asiwo chine kusimba kwerabha uye purasitiki. Kunewo hunhu husina mapurasitiki echinyakare: haanyorove mushure mekudziya.
