Isiphumo sokuzicoca se-Super Hydrophobic Surface

I-Wettability yinto ebalulekileyo yendawo eqinile, echongwa yi-chemical composition kunye ne-morphology yomhlaba. Super-hydrophilic kunye super hydrophobic iimpawu zomphezulu zezona ziqulatho ziphambili zophononongo olungenelelayo. I-superhydrophobic (egxotha amanzi) ijini yangaphezulurally ibhekisa kumphezulu ukuba i-engile yoqhagamshelwano phakathi kwamanzi kunye nomphezulu ingaphezulu kwe-150 degrees. Into yokuba abantu bazi umphezulu we-superhydrophobic ubukhulu becala kumagqabi esityalo-igqabi lelotus, into “yokuzicoca”. Umzekelo, amathontsi amanzi anokuqengqeleka ukuze aqengqeleke kumphezulu wegqabi lelotus, nokuba amanye amanzi amdaka agalela egqabini, awayi kushiya ibala emagqabini. Iimpawu ezinjalo zeqabunga le-lotus ezingabonakaliyo zibizwa ngokuba yimpembelelo "yokuzicoca".

Isiphumo seLotus-Umgaqo-siseko we-Super hydrophobic

Nangona abantu besazi kwangoko kakhulu isiphumo segqabi lelotus “sokuzicoca”, kodwa abakwazanga ukuqonda imfihlo yomphezulu wamagqabi elotus. Kude kube ngoo-1990, izazinzulu ezimbini zaseJamani zaqala zaqaphela nge-electron yokuskena i-microscope, i-microstructure ye-lotus leaf surface, ukuba isiphumo "sokuzicoca" sibangelwa yi-micron mastoid kunye ne-lotus leaf surface wax phezu komhlaba. Emva koko, ooSonzululwazi bahlalutya nzulu umphezulu wesakhiwo se-lotus segqabi le-micron kwaye bafumanisa ukuba kukho i-nanostructures kwi-lotus leaf surface mastoid, ngelixa olu lwakhiwo lumbini lwe-micron kunye ne-nano-structure zizinto ezibangela "ukuzicoca" indawo yegqabi lelotus.

Kutheni le nto "irhabaxa" enjalo inokuvelisa i-superhydrophobic

Kumphezulu oqinileyo we-hydrophobic, xa umphezulu unoqikelelo oluncinci, omnye womoya uya “kusuka uye” phakathi kwamanzi kunye nemigangatho eqinileyo, ekhokelela kumathontsi amanzi uninzi lokudibana nomoya, kodwa ukunxibelelana ngokuthe ngqo neendawo eziqinileyo kakhulu. iyancipha. Ukusukela ukuxinana komphezulu wamathontsi amanzi amile ukuze indawo erhabaxa isondele kwingqukuva, i-engile yoqhagamshelwano ifikelela kuma-degrees ayi-150, kwaye amathontsi amanzi phezu komhlaba angaqengqeleka akhululeke.

Nangona ezinye zezinto ezingcolileyo eziphezu komhlaba, ziya kuqengqeleka, ngoko umphezulu uya kuba nekhono "lokuzihlambulula". Lo mhlaba une-angle yoqhagamshelwano engaphezulu kwe-150 degrees ubizwa ngokuba "yi-super-hydrophobic surface", kunye ne-angle yoqhagamshelwano yejini.ral umphezulu we-hydrophobic mkhulu kuphela kune-90 degrees.

Kwindaloral ihlabathi, ngaphandle kokuba igqabi lelotus linamandla "wokuzihlambulula", kukho ezinye ezifana nerayisi, izityalo zetaro kunye neentsiba ezinjengeentaka. , kunye nokuthintela ukuhlasela kwe-pathogens. Ngenxa yokuba kunye ne-pathogen kumphezulu weqabunga, iya kuhlanjwa. Ke ngolu hlobo, nkqu nesityalo selotus esikhula kwindawo “emdaka” akulula ukugula, isizathu esibaluleke kakhulu kungenxa yesi sixhobo sokuzicoca.
