Nazarin Superhydrophobic Biomimetic Surfaces

Abubuwan da ke saman kayan suna da mahimmanci sosai, kuma masu bincike suna ƙoƙarin kowane nau'ikan hanyoyin don samun saman kayan tare da kaddarorin da ake buƙata. Tare da haɓaka aikin injiniya na bionic, masu bincike suna ba da hankali ga farfajiyar halittu don fahimtar yadda yanayin zai iya magance matsalolin injiniya. Binciken da aka yi akan filayen halittu ya nuna cewa waɗannan saman suna da wasu abubuwan da ba a saba gani ba. "Tasirin magarya" wani abu ne na al'ada wanda natural tsarin saman kamar yadda ake amfani da zane don ƙirƙira da ƙirƙira saman kayan aikin injiniya. Tsarin binary microstructure na lotus surface yana ba da super-hydrophobicity, wanda zai iya dacewa da yanayin muhalli da kyau. A cikin 'yan shekarun nan, da superhydrophobic biomimetic surfaces An yi nazari sosai saboda wajibcin kayan tsaftacewa, na'urar micro-fluid da sauran su.

Abubuwan da aka yi wahayi zuwa superhydrophobic ana shirya su ta hanyoyi da yawa bisa ga ka'idodin jiki da sinadarai, kamar lithography, hanyar samfuri, sublimation, hanyoyin electrochemical, hanyoyin Layer-by-Layer, tsarin ƙasa don ƙirƙira nano-arrays da sauransu. . Koyaya, masu bincike galibi suna ƙirƙira fina-finai na hydrophobic akan kayan ƙarfe da saman kayan da ba a haɗa su ba tare da ingantaccen sinadari. Don haka, ba a cika yin bincike akan ƙarfe mai amsawa da abubuwan da suke da shi ba. Magnesium yana ɗaya daga cikin kayan aikin injiniya mafi sauƙi. Don haka, ana sa ran za a yi amfani da magnesium da kayan aikin sa a sararin samaniya, jiragen sama, motoci, da aikace-aikacen jirgin ƙasa.

Rufin hydrophobic zai zama fasaha mai ban sha'awa don inganta aikin farfajiya. Jiang da al.[1] ƙirƙira wani super-hydrophobic biomimetic surface a kan Mg-Li gami ta hanyar sinadarai etching, bi da nutsewa da annealing matakai ta amfani da fluoroalkylsilane (FAS) kwayoyin. Hakazalika, Ishizaki et al. [2] ya ƙirƙiri wani wuri mai girma-hydrophobic akan alloy na magnesium ta hanyar nutsewa a cikin maganin ruwa na cerium nitrate (minti 20). Jun et al. [3] ya ƙirƙiri wani barga na biomimetic super-hydrophobic surface akan magnesium gami da aka ƙera ta hanyar pretreatment na microarc oxidation kuma ya biyo bayan gyare-gyaren sinadarai dangane da tasirin lotus. Li et al. [4] shirya fina-finan bakin ciki na magnesium ta hanyar bias magnetron sputtering.
