Pa June 8, 2023, Pulofesa Tang Ruikang ndi wofufuza Liu Zhaoming wochokera ku Dipatimenti ya Chemistry ku Zhejiang University adalengeza za kupanga "pulasitiki yosalala ya ceramic". Ichi ndi chinthu chatsopano chomwe chimaphatikiza kuuma ndi kufewa, ndi kuuma kofanana ndi ceramic, kusinthasintha kofanana ndi rabara, ndi pulasitiki yofanana ndi plastic.
Kodi ichi ndi pulasitiki yowonekera bwino kapena ceramic? Ndi pulasitiki yosalala yopangidwa ndi gulu la Zhejiang University.
"Mapulasitiki opangidwa ndi ceramic otanuka" ndi nthawi yoyamba kuzindikira kuphatikiza kwa mankhwala achilengedwe ndi mankhwala a Ionic osapangidwa ndi organic pamlingo wa mamolekyulu, kuti apeze zinthu zatsopano zokhala ndi makhalidwe osiyana ndi zinthu zakale. Mu chidziwitso chachikhalidwe, njira zokonzekera zinthu m'munda wa Inorganic chemistry ndi Polymer chemistry ndizosiyana kwambiri. Zanenedwa kuti "pulasitiki yotanuka ya ceramic" yopangidwa ndi mamolekyu osakanizidwa mu labotale ndi thupi laling'ono lachikasu lofanana ndi batani. Mu mamolekyu ake, netiweki ya ionic bond yosapangidwa ndi netiweki ya organic Covalent bond zimalumikizana ndikusakanikirana, zomwe sizimangokhala ndi makhalidwe a zinthu zosapangidwa ndi organic, komanso zimasunga mawonekedwe a zinthu zachilengedwe, ndipo zimakhala ndi kuuma ndi kusinthasintha kwina. Mphamvu inayake yakunja ikagwiritsidwa ntchito, mafupa osapangidwa ndi organic amatha kupereka kuuma ndi mphamvu; Mphamvu yakunja ikakhala yayikulu ndipo kusintha kwa elastic kumachitika, mafupa onse amasokonekera, ndikupanga mphamvu yolumikizira; Pambuyo pochotsa mphamvu zakunja, mafupa achilengedwe amakhala ndi mphamvu yobwerera, ndikubwezeretsa netiwekiyo ku mkhalidwe wake woyambirira. Kale, organic-inorganic fusion inali superposition yosavuta, monga kutsanulira ufa wosapangidwa ndi organic mu chimango cha organic ndikusakaniza mofanana. Ngati mugawa gawo ndi gawo, mulingo wa mamolekyu ukadali "ndinu wanu, ine ndine wanga", kungokhala kusakaniza kwa awiriwa, "kuyesera kumeneku kunapanga mamolekyu atsopano omwe sanalipo kale, kunapeza kapangidwe katsopano, ndikuswa chotchinga pakati pa mankhwala achilengedwe ndi mankhwala a Ionic osapangidwa pamlingo wa mamolekyu."
Asayansi a ku Zhejiang University ayerekeza momwe zinthu zatsopanozi zimagwirira ntchito ndi zinthu zadothi, rabala, mapulasitiki, zitsulo, ndi zina. Zapeza zigoli zambiri pakulimba, kubweza, mphamvu, kusintha, ndi kusinthasintha. Sikuti zimangolimba ngati marble, komanso zimakhala ndi kulimba ngati rabala komanso kulimba ngati pulasitiki. Palinso makhalidwe omwe mapulasitiki akale alibe: safewa akatenthedwa.
