Ihe karịrị 30 stoichiometric MXenes ka ewepụtalarị, yana ọtụtụ MXenes ngwọta siri ike.MXene ọ bụla nwere ngwa anya pụrụ iche, eletrọnịkị, anụ ahụ na kemịkalụ, na-eduga n'iji ha eme ihe n'ihe fọrọ nke nta ka ọ bụrụ ubi ọ bụla, site na biomedicine ruo nchekwa ike elektrọn.Ọrụ anyị na-elekwasị anya na njikọ nke usoro MAX dị iche iche na MXenes, gụnyere ihe nhazi ọhụrụ na ihe owuwu, na-ekpuchi kemịkalụ M, A, na X, na site na iji usoro MXene niile mara amara.Ndị a bụ ụfọdụ ntụziaka anyị na-agbaso:
1. Iji otutu M-chemistry
Iji mepụta MXenes nwere ihe ndị a na-emegharị emegharị (M'yM”1-y)n+1XnTx, iji mee ka ihe owuwu nke na-adịbughị tupu (M5X4Tx) guzosie ike, na n'ozuzu ikpebi mmetụta kemịkalụ na akụrụngwa MXene.
2. Synthesis nke MXenes sitere na akụkụ MAX na-abụghị nke aluminom
MXenes bụ klas nke ihe 2D arụpụtara site na kemịkalụ etching nke A element na usoro MAX.Ebe ọ bụ na achọpụtara ha ihe karịrị afọ 10 gara aga, ọnụ ọgụgụ MXenes dị iche iche amụbaala nke ukwuu iji tinye ọtụtụ MnXn-1 (n = 1,2,3,4, ma ọ bụ 5), ngwọta ha siri ike (nyere iwu na enweghị nsogbu), na oghere oghere.A na-emepụta ọtụtụ MXenes site na aluminom MAX usoro, ọ bụ ezie na e nweela akụkọ ole na ole nke MXenes sitere na ihe ndị ọzọ A (dịka, Si na Ga).Anyị na-achọ ịgbasa ọbá akwụkwọ nke MXenes nwere ike ịnweta site na ịmepụta usoro etching (dịka ọmụmaatụ, ngwakọta acid, nnu a wụrụ awụ, wdg) maka usoro MAX ndị ọzọ na-abụghị aluminom na-eme ka ọmụmụ nke MXenes ọhụrụ na ihe onwunwe ha.
3. Etching kinetics
Anyị na-agbalị ịghọta kinetics nke etching, otú etching kemịkalụ emetụta MXene Njirimara, na otú anyị nwere ike iji nke a ihe ọmụma na-ebuli njikọ nke MXenes.
4. New obibia na delamination nke MXenes
Anyị na-eleba anya n'usoro nwere ike ime ka o kwe omume nke MXenes' delamination.
