A ranar 8 ga Yuni, 2023, Farfesa Tang Ruikang da mai bincike Liu Zhaoming daga Sashen Chemistry na Jami'ar Zhejiang sun ba da sanarwar haɗin "robo mai roba na roba". Wannan sabon abu ne wanda ya haɗu da tauri da laushi, tare da yumbu kamar taurin, roba kamar elasticity, da filastik kamar filastik.
Shin wannan abu na fili ne filastik ko yumbu? Roba ceramik na roba ne wanda ƙungiyar jami'ar Zhejiang ta shirya.
"Plastics ceramic robobi" shine karo na farko don gane haɗuwa da kwayoyin halitta da kuma inorganic Ionic fili a matakin kwayoyin halitta, don samun sababbin kayan aiki tare da kaddarorin da suka bambanta da kayan da suka gabata. A cikin fahimtar al'ada, hanyoyin shirye-shiryen kayan aiki a fagen Inorganic Chemistry da Polymer chemistry sun bambanta sosai. An ba da rahoton cewa "roba mai roba yumbura" polymerized ta hanyar kwayoyin halitta a cikin dakin gwaje-gwaje karamin maballin rawaya ne kamar jiki. A cikin kwayoyin halittarsa, cibiyar sadarwa ta inorganic ionic bond da kuma hanyar sadarwa ta Covalent bond suna hade da juna, wanda ba wai kawai yana da kaddarorin kayan da ba a iya amfani da su ba, amma kuma yana da halaye na kayan halitta, kuma yana da wani tauri da elasticity. Lokacin da aka yi amfani da wani ƙarfin waje, kwarangwal na inorganic zai iya ba da tauri da ƙarfi; Lokacin da ƙarfin waje ya yi girma kuma nakasar na roba ta faru, dukkanin kwarangwal sun lalace, suna haifar da tasirin buffer; Bayan cire sojojin waje, kwarangwal na kwayoyin halitta yana yin tasiri mai tasiri, yana maido da hanyar sadarwa zuwa matsayinta na asali. A da, haɗakar kwayoyin halitta-inorganic abu ne mai sauƙi mai sauƙi, kamar zuba foda na inorganic a cikin tsarin kwayoyin halitta kuma yana motsawa daidai. Idan ka rarraba Layer ta Layer, matakin kwayoyin har yanzu "kai naka ne, ni nawa ne", kawai cakuda biyun, "wannan gwaji ya haifar da sababbin kwayoyin da ba a baya ba, sun sami sabon tsari, kuma ya karya shingen da ke tsakanin mahadin kwayoyin halitta da mahallin Ionic inorganic a sikelin kwayoyin.”
Masana kimiyya na jami'ar Zhejiang sun kwatanta aikin wannan sabon kayan da yumbu, roba, robobi, karafa, da sauransu. Ya sami babban maki a cikin taurin, sake dawowa, ƙarfi, nakasawa, da iya aiwatarwa. Ba wai kawai yana da taurin matakin marmara ba, har ma yana da elasticity na roba da kuma robobi na robobi. Hakanan akwai halayen da robobi na gargajiya ba su da: ba sa laushi bayan dumama.
