Ikhuthazwe kukuguquguquka kunye nokuqina kwewebhu ze-spider silks, iqela lophando elikhokelwa nguProf. YU Shuhong ovela kwiYunivesithi yeSayensi kunye neTekhnoloji yaseChina (USTC) lenze indlela elula neqhelekileyo yokwenza i-superelastic kunye ne-fatigue resistant hard carbon aerogels nge-nanofibrous. isakhiwo senethiwekhi ngokusebenzisa i-resorcinol-formaldehyde resin njengomthombo wekhabhoni onzima.

Kumashumi eminyaka akutshanje, ii-aerogels zekhabhoni ziye zaphononongwa ngokubanzi ngokusebenzisa iikhabhoni zegraphic kunye neekhabhoni ezithambileyo, ezibonisa inzuzo kwi-superelasticity. Ezi aerogels ezinwebekayo zihlala zinemikrozo ethambileyo enokumelana nokudinwa okuhle kodwa amandla aphantsi. Iikhabhoni ezinzima zibonisa inzuzo enkulu kumandla omatshini kunye nokuzinza kwesakhiwo ngenxa yesakhiwo se-sp3 C-induced turbostratic "house-of-cards". Nangona kunjalo, ukuqina kunye ne-fragility kungena ngokucacileyo kwindlela yokuphumeza i-superelasticity kunye neekhabhoni ezinzima. Ukuza kuthi ga ngoku, kusengumceli mngeni ukwenza ii-aerogels ze-superelastic hard carbon-based.

I-polymerization ye-resin monomers yaqalwa phambi kwee-nanofibers njengeetemplates zesakhiwo ukulungiselela i-hydrogel ene-nanofibrous networks, ilandelwa ukomisa kunye ne-pyrolysis ukufumana i-carbon aerogel enzima. Ngexesha le-polymerization, i-monomers idiphozithi kwiitemplates kwaye idibanise i-fiber-fiber joints, ishiya isakhiwo sothungelwano esingacwangciswanga esinamalungu amakhulu omelele. Ngaphezu koko, iipropathi ezibonakalayo (ezinje ngeedayamitha ze-nanofiber, ingxinano ye-aerogels, kunye neempawu zomatshini) zinokulawulwa ngokulungisa itemplates kunye nobungakanani bemathiriyeli ekrwada.

Ngenxa yobunzima bekhabhoni nanofibers kunye namalungu amaninzi adityanisiweyo phakathi kwe-nanofibers, ii-aerogels zekhabhoni eziqinileyo zibonisa ukusebenza okuqinileyo kunye nokuzinza komatshini, kubandakanya ukuqina okuphezulu, amandla aphezulu, isantya esikhawulezayo sokubuyisela (860 mm s-1) kunye ne-coefficient yokulahleka kwamandla. <0.16). Emva kokuvavanya phantsi kwe-50% yoxinzelelo kwimijikelezo ye-104, i-carbon airgel ibonisa kuphela i-2% ye-deformation yeplastiki, kwaye igcine i-93 % yoxinzelelo lwangaphambili.

I-airgel yekhabhoni enzima inokugcina i-super-elasticity kwiimeko ezinzima, ezifana ne-nitrogen engamanzi. Ngokusekelwe kwiimpawu ezikhangayo zomatshini, le nqwelo-moya ye-carbon airgel inesithembiso ekusetyenzisweni kweenzwa zoxinzelelo kunye nozinzo oluphezulu kunye noluhlu olubanzi lwe-detective (50 KPa), kunye nabaqhubi abanokwelula okanye abagobayo. Le ndlela ibambe isithembiso sokwandiswa ukwenza ezinye ii-nanofibers ezihlangeneyo ezingenayo ikhabhoni kwaye zibonelela ngendlela ethembisayo yokuguqula izinto eziqinileyo zibe yi-elastic okanye izinto eziguquguqukayo ngokuyila i-nanofibrous microstructures.
