Ngomhlaka-8 Juni 2023, uSolwazi Tang Ruikang kanye nomcwaningi uLiu Zhaoming ovela eMnyangweni WezeKhemistri eYunivesithi yaseZhejiang bamemezele ukuhlanganiswa “kwepulasitiki ye-ceramic enwebekayo”. Lokhu kuyinto entsha ehlanganisa ubulukhuni nobuthambile, nobulukhuni obufana ne-ceramic, ukunwebeka okufana nerabha, kanye nobupulasitiki obufana neplastiki.
Ingabe lokhu kuyipulasitiki noma ipulasitiki ecacile? Kuyipulasitiki ethambile eyenziwe yithimba leYunivesithi yaseZhejiang.
"Amapulasitiki e-ceramic anwebekayo" yisikhathi sokuqala sokuthola inhlanganisela yamakhemikhali e-organic kanye ne-inorganic Ionic compound ezingeni lama-molecule, ukuze kutholakale izinto ezintsha ezinezakhiwo ezihlukile ezintweni zangaphambilini. Ekuqondeni kwendabuko, izindlela zokulungiselela izinto emkhakheni we-Inorganic chemistry kanye ne-Polymer chemistry zihluke ngokuphelele. Kubikwa ukuthi "ipulasitiki ye-ceramic enwebekayo" eyenziwe nge-polymer ngama-molecule e-hybrid elabhorethri ingumzimba omncane ophuzi ofana nenkinobho. Kuma-molecule ayo, inethiwekhi ye-ionic bond e-inorganic kanye nenethiwekhi ye-organic Covalent bond ziyahlangana futhi ziyaxubana, ezingagcini nje ngokuba nezakhiwo zezinto ezi-inorganic, kodwa futhi zigcina izici zezinto eziphilayo, futhi zinobulukhuni nokunwebeka okuthile. Lapho kusetshenziswa amandla athile angaphandle, i-inorganic skeleton inganikeza ubulukhuni namandla; Lapho amandla angaphandle emakhulu futhi kwenzeka ukuguqulwa kwe-elastic, lonke i-skeleton liyashintshashintsha, likhiqize umphumela wokubopha; Ngemva kokususa amandla angaphandle, i-organic skeleton iveza umphumela wokubuyela emuva, ibuyisele inethiwekhi esimweni sayo sokuqala. Esikhathini esidlule, ukuhlanganiswa kwezinto eziphilayo-ezi-organic kwakuyi-superposition elula, njengokuthela i-inorganic powder ohlakeni lwezinto eziphilayo bese ivuselela ngokulinganayo. Uma uhlukanisa ungqimba ngengqimba, izinga lama-molecule lisalokhu lithi “ungowakho, ngingowami”, ingxube nje yalokhu okubili, “lokhu kuhlola kwakhiqiza ama-molecule amasha ayengekho esikhathini esidlule, kwathola isakhiwo esisha, futhi kwaphula umgoqo phakathi kwamakhemikhali e-organic kanye ne-inorganic Ionic compound esikalini sama-molecule.”
Ososayensi baseYunivesithi yaseZhejiang baqhathanise ukusebenza kwale nto entsha nezinto zobumba, irabha, ipulasitiki, izinsimbi, nokunye. Ithole amaphuzu aphezulu ebulukhunini, ekubuyiseleni emuva, emandleni, ekuguqukeni nasekucutshungulweni kalula. Ayigcini nje ngokuba nobulukhuni bezinga lemabula, kodwa futhi inokuqina kwerabha kanye nokuqina kwepulasitiki. Kukhona nezici amapulasitiki endabuko angenazo: awathambi ngemva kokushisa.
Isikhathi sokuthunyelwe: Julayi-25-2023
