NgoJuni 8, 2023, uNjingalwazi uTang Ruikang kunye nomphandi uLiu Zhaoming ovela kwiSebe leKhemistri kwiYunivesithi yaseZhejiang babhengeze udityaniso lwe “elastic ceramic plastic”.Le yimathiriyeli entsha edibanisa ubulukhuni kunye nokuthamba, kunye ne-ceramic efana nobulukhuni, irabha efana ne-elasticity, kunye neplastiki njengeplastiki.
Ngaba le nto yeplastiki ebonakalayo okanye i-ceramic?Yiplastiki ye-elastic ceramic elungiselelwe liqela leYunivesithi yaseZhejiang.
"Iiplastiki ze-ceramic ze-elastic" lixesha lokuqala ukuqonda indibaniselwano ye-organic compounds kunye ne-inorganic Ionic ikhompawundi kwinqanaba le-molecular, ukuze ufumane izinto ezintsha ezineepropati ezahlukileyo kwizinto zangaphambili.Kwingqiqo yendabuko, iindlela zokulungiselela izinto kwintsimi ye-Inorganic chemistry kunye ne-Polymer chemistry zihluke ngokupheleleyo.Kuxelwa ukuba "iplastiki ye-ceramic ethambileyo" eyenziwe ipholima ngeemolekyuli ezixubileyo kwilabhoratri liqhosha elincinci elimthubi njengomzimba.Kwiimolekyuli zayo, i-inorganic ionic bond network kunye ne-organic bond ye-Covalent network idityanisiwe kwaye idibene, engenazo iimpawu zezinto eziphathekayo, kodwa igcina iimpawu zezinto eziphilayo, kwaye inobunzima obuthile kunye nokuqina.Xa kusetyenziswe amandla athile angaphandle, i-inorganic skeleton inokubonelela ngobulukhuni kunye namandla;Xa amandla angaphandle makhulu kwaye i-elastic deformation iyenzeka, i-skeleton yonke iyancipha, ivelise umphumo wokuphazamisa;Emva kokususa amandla angaphandle, i-organic skeleton yenza i-rebound effect, ibuyisela inethiwekhi kwindawo yayo yokuqala.Ngaphambili, i-organic-inorganic fusion yayiyinto elula kakhulu, njengokugalela umgubo we-inorganic kwisakhelo se-organic kwaye ushukumisa ngokulinganayo.Ukuba wahlulahlula umaleko ngokomaleko, inqanaba lemolekyuli “usengowakho, ndingowam”, umxube nje wemibini, “olu vavanyo luvelise iimolekyuli ezintsha ezazingekho ngaphambili, lwafumana isakhiwo esitsha, kwaye waphula umqobo phakathi kweekhompawundi ze-organic kunye ne-inorganic Ionic ikhompawundi kwi-molecular scale.
Izazinzulu zeYunivesithi yaseZhejiang zithelekise ukusebenza kwesi sixhobo sitsha kunye neeseramikhi, irabha, iiplastiki, isinyithi, kunye nezinye.Ifumene amanqaku aphezulu kubulukhuni, ukuphindaphinda, amandla, ukuguqulwa, kunye nokuqhubekeka.Ayinabulukhuni benqanaba lebhastile kuphela, kodwa inokwaluka kwerabha kunye neplastiki yeeplastiki.Kukho neempawu ezingenazo iiplastiki zemveli: azithambi emva kokufudumeza.
