Ma MXene opitilira 30 a stoichiometric apangidwa kale, okhala ndi ma MXenes owonjezera olimba.MXene iliyonse ili ndi mawonekedwe apadera a kuwala, zamagetsi, thupi, ndi mankhwala, zomwe zimapangitsa kuti azigwiritsidwa ntchito pafupifupi m'munda uliwonse, kuchokera ku biomedicine mpaka kusungirako mphamvu zamagetsi.Ntchito yathu imayang'ana pa kaphatikizidwe ka magawo osiyanasiyana a MAX ndi ma MXenes, kuphatikiza nyimbo ndi zida zatsopano, zoyambira m'makhemistri onse a M, A, ndi X, komanso kugwiritsa ntchito njira zonse zodziwika za MXene.Nawa ena mwa njira zomwe tikutsatira:
1. Kugwiritsa ntchito ma Chemistries angapo
Kupanga ma MXenes okhala ndi zinthu zosinthika (M'yM”1-y)n+1XnTx, kuti akhazikitse zomanga zomwe sizinakhalepo kale (M5X4Tx), ndikuwunika momwe chemistry imakhudzira katundu wa MXene.
2. Kaphatikizidwe ka MXenes kuchokera ku magawo omwe si aluminiyamu MAX
MXenes ndi gulu la zida za 2D zopangidwa ndi ma etching a mankhwala a element A mu magawo MAX.Chiyambireni kupezeka zaka 10 zapitazo, chiwerengero cha MXenes osiyana chakula kwambiri kuphatikizapo MnXn-1 (n = 1,2,3,4, kapena 5), mayankho awo olimba (olamulidwa ndi osokonezeka), ndi zolimba zapakhomo.Ma MXenes ambiri amapangidwa kuchokera ku aluminiyamu MAX magawo, ngakhale pakhala pali malipoti ochepa a MXenes opangidwa kuchokera kuzinthu zina za A (mwachitsanzo, Si ndi Ga).Tikufuna kuwonjezera laibulale ya MXenes Kufikika popanga ndondomeko etching (mwachitsanzo, asidi wosakaniza, mchere wosungunula, etc.) kwa ena sanali aluminiyamu MAX magawo kutsogoza kuphunzira MXenes latsopano ndi katundu wawo.
3. Etching kinetics
Tikuyesera kumvetsetsa kinetics ya etching, momwe etching chemistry imakhudzira katundu wa MXene, ndi momwe tingagwiritsire ntchito chidziwitsochi kuti tikwaniritse kaphatikizidwe ka MXenes.
4. Njira zatsopano za delamination za MXenes
Tikuyang'ana njira zowonongeka zomwe zimalola mwayi wa MXenes 'delamination.
