Ligqugquzelwe ukuguquguquka nokuqina kolwembu lwesicabucabu semvelo, ithimba labacwaningi eliholwa nguProf. YU Shuhong waseNyuvesi Yesayensi Nobuchwepheshe YaseChina (USTC) lenze indlela elula nevamile yokwenza ama-aerogel aqinile ekhabhoni aqinile ane-nanofibrous ane-superelastic kanye nokukhathala. isakhiwo senethiwekhi ngokusebenzisa i-resorcinol-formaldehyde resin njengomthombo wekhabhoni eqinile.

In recent decades, carbon aerogels have been widely explored by using graphitic carbons and soft carbons, which show advantages in superelasticity. These elastic aerogels usually have delicate microstructures with good fatigue resistance but ultralow strength. Hard carbons show great advantages in mechanical strength and structural stability due to the sp3 C-induced turbostratic “house-of-cards” structure. However, the stiffness and fragility clearly get in the way of achieving superelasticity with hard carbons. Up to now, it is still a challenge to fabricate superelastic hard carbon-based aerogels.

I-polymerization yama-resin monomers yaqalwa phambi kwama-nanofibers njengezifanekiso zesakhiwo ukulungiselela i-hydrogel enamanethiwekhi e-nanofibrous, okulandelwa ukomiswa kanye ne-pyrolysis ukuze kutholakale i-hard carbon aerogel. Ngesikhathi se-polymerization, ama-monomers afaka ezifanekisweni futhi ashise amalunga e-fiber-fiber, okushiya uhlaka lwenethiwekhi olungahleliwe olunamajoyini amakhulu aqinile. Ngaphezu kwalokho, izakhiwo ezibonakalayo (ezifana namadayamitha we-nanofiber, ukuminyana kwama-aerogel, kanye nezakhiwo eziwumshini) zingalawulwa ngokumane kushunwe izifanekiso kanye nenani lezinto zokusetshenziswa.

Ngenxa yama-carbon nanofibers aqinile kanye namajoyinti ashiselwe amaningi phakathi kwama-nanofibers, ama-aerogel ekhabhoni aqinile abonisa ukusebenza kwemishini okuqinile nokuzinzile, okuhlanganisa ukunwebeka okukhulu, amandla aphezulu, isivinini sokululama ngokushesha kakhulu (860 mm s-1) kanye ne-coefficient yokulahlekelwa amandla okuphansi ( <0.16). Ngemva kokuhlolwa ngaphansi kwe-50 % uhlobo lwemijikelezo engu-104, i-carbon airgel ibonisa kuphela ukuguqulwa kwepulasitiki okungu-2%, futhi igcine ukucindezeleka kwasekuqaleni okungama-93%.

I-hard carbon airgel ingagcina i-super-elasticity ezimweni ezinzima, njenge-nitrogen eyi-liquid. Ngokusekelwe ezicini ezihehayo zemishini, le-airgel ye-carbon eqinile inesithembiso ekusetshenzisweni kwezinzwa zokucindezeleka ezinokuzinza okuphezulu nobubanzi babaseshi obubanzi (50 KPa), kanye namakhondaktha anwebekayo noma agobekayo. Le ndlela inesithembiso sokunwetshwa ukuze kwenziwe amanye ama-nanofiber ayinhlanganisela asekelwe kukhabhoni futhi inikeza indlela ethembisayo yokuguqula izinto eziqinile zibe izinto ezinwebekayo noma eziguquguqukayo ngokuklama ama-nanofibrous microstructures.
