Ọmụmụ nke Superhydrophobic Biomimetic Surfaces

Ngwongwo elu nke ihe dị oke mkpa, ndị na-eme nchọpụta na-agbalịkwa ụdị ụzọ ọ bụla iji nweta ihe ndị dị n'elu na ihe ndị achọrọ. Site na mmepe nke injinia bionic, ndị na-eme nchọpụta na-elebawanye anya na mbara igwe ka ha wee ghọta otú okike nwere ike isi dozie nsogbu injinia. Nnyocha ndị e mere n'elu ihe ndị dị ndụ egosila na elu ndị a nwere ọtụtụ ihe ndị pụrụ iche. "Lotus-mmetụta" bụ ihe a na-ahụkarị nke natural Ọdịdị elu dị ka a na-eji ụkpụrụ ụkpụrụ arụpụta na imepụta ihe ndị injinia dị elu. Microstructure ọnụọgụ abụọ nke elu lotus na-enye super-hydrophobicity, nke nwere ike ime mgbanwe na ọnọdụ gburugburu ebe obibi nke ọma. Na-adịbeghị anya, na superhydrophobic biomimetic elus a mụọla nke ọma n'ihi mkpa nke ihe na-ehicha onwe ya, ngwaọrụ micro-fluid na ndị ọzọ.

A na-eji ọtụtụ ụzọ edozi ihe ndị dị n'ike mmụọ nsọ nke superhydrophobic elu site n'ọtụtụ ụzọ dị ka ụkpụrụ anụ ahụ na nke kemịkal siri dị, dị ka lithography, usoro template, sublimation, usoro electrochemical, ụzọ oyi akwa, usoro mgbago elu maka imepụta nano-arrays na ihe ndị ọzọ. . Agbanyeghị, ndị na-eme nchọpụta na-ekepụta ihe nkiri hydrophobic n'ihe igwe na ihe inorganic nwere akụrụngwa kemịkalụ kwụsiri ike. N'ihi ya, a naghị adịkarị enyocha igwe na-emeghachi omume na elu ha. Magnesium bụ otu n'ime ihe injinịa kacha dị mfe. Ya mere, a na-atụ anya na a ga-eji magnesium na alloys mee ihe na mbara igwe, ụgbọ elu, ụgbọ ala, na ngwa ụgbọ okporo ígwè.

Ihe mkpuchi hydrophobic ga-abụ teknụzụ na-ekwe nkwa maka imeziwanye arụmọrụ elu. Jiang et al.[1] kpụrụ a super-hydrophobic biomimetic elu on a Mg-Li alloy site kemịkalụ etching, sochiri imikpu na annealing Filiks site na iji fluoroalkylsilane (FAS) molekul. N'otu aka ahụ, Ishizaki et al. [2] mepụtara elu-hydrophobic elu na magnesium alloy site na imikpu na cerium nitrate mmiri ngwọta (20 min). Jun et al. [3] mepụtara elu biomimetic super-hydrophobic kwụsiri ike n'elu magnesium alloy nke microarc oxidation pretreatment mebere wee megharịa kemịkalụ dabere na mmetụta lotus. Li et al. [4] kwadebere ihe nkiri ndị dị mkpa na magnesium site n'ịgbasa ihe na-adịghị mma.
