Ngomhla ziyisi-8 kuNhlangulana 2023, uSolwazi Tang Ruikang kanye nomcwaningi uLiu Zhaoming ovela eMnyangweni Wezekhemikhali eNyuvesi yaseZhejiang bamemezele ukuhlanganiswa “kwepulasitiki yobumba obunwebekayo”.Lena into entsha ehlanganisa ubulukhuni nokuthambile, enobumba obuqinile obunjengokuqina, irabha efana nokunwebeka, nepulasitiki efana nepulasitiki.
Ingabe lokhu kuyipulasitiki esobala noma i-ceramic?Ipulasitiki ye-ceramic enwebekayo elungiselelwe iqembu laseZhejiang University.
"Amapulasitiki e-Elastic Ceramic" yisikhathi sokuqala ukubona inhlanganisela yezinto eziphilayo kanye nenhlanganisela ye-Ionic ye-inorganic ezingeni lamangqamuzana, ukuze kutholwe izinto ezintsha ezinezakhiwo ezihlukile kwezangaphambili.Ngokwazi kwendabuko, izindlela zokulungiselela zezinto zokwakha emkhakheni we-Inorganic chemistry kanye ne-Polymer chemistry zihluke ngokuphelele.Kubikwa ukuthi “ipulasitiki yobumba obunwebekayo” eyenziwe i-polymerized ngama-molecule ayingxube elabhorethri iyinkinobho encane ephuzi njengomzimba.Emangqamuzaneni ayo, inethiwekhi ye-inorganic ionic bond kanye ne-organic Covalent bond network ihlanganiswe futhi ihlanganiswe, engagcini nje ngokuba nezakhiwo zezinto ezingaphili, kodwa futhi igcina izici zezinto eziphilayo, futhi inobulukhuni nokunwebeka okuthile.Lapho kusetshenziswa amandla athile angaphandle, uhlaka lwamathambo ezinto ezingaphili lunganikeza ubulukhuni namandla;Lapho amandla angaphandle emakhulu futhi ukuwohloka okunwebeka kwenzeka, wonke uhlaka lwamathambo luyashintsha, lukhiqize umphumela wokubhafa;Ngemva kokukhipha amandla angaphandle, i-organic skeleton yenza umphumela wokuphindaphinda, ukubuyisela inethiwekhi esimweni sayo sokuqala.Esikhathini esedlule, i-organic-inorganic fusion yayiyi-superposition elula, njengokuthela impushana ye-inorganic ohlakeni lwezinto eziphilayo futhi igovuze ngokulinganayo.Uma uhlukanisa ungqimba ngongqimba, izinga lamangqamuzana kusewukuthi “ungowakho, ngingowami”, ingxubevange nje yalokhu okubili, “lokhu kuhlola kwakhiqiza ama-molecule amasha ayengekho esikhathini esidlule, athola isakhiwo esisha, futhi. wephule umgoqo phakathi kwezinhlanganisela zezinto eziphilayo kanye nenhlanganisela ye-Ionic engaphili esikalini samangqamuzana.”
Ososayensi baseNyuvesi yaseZhejiang baqhathanise ukusebenza kwalokhu okusha nezinto zobumba, irabha, amapulasitiki, izinsimbi nokunye.Izuze amaphuzu aphezulu ebukhuni, ukubopha kabusha, amandla, ukuguquguquka, kanye nokucutshungulwa.Ayigcini nje ngokuba nobulukhuni bezinga lemabula, kodwa futhi inokuqina kwerabha kanye nepulasitiki yamapulasitiki.Kukhona futhi izici amapulasitiki endabuko angenazo: awathambisi ngemva kokushisa.
