Umthelela wokuzihlanza we-Super Hydrophobic Surface

Ukumanzisa kuyisici esibalulekile sendawo eqinile, enqunywa ukwakheka kwamakhemikhali kanye ne-morphology yendawo. Super-hydrophilic futhi super hydrophobic izici ezingaphezulu ziwukuqukethwe okuyinhloko kwezifundo ezihlaselayo. I-superhydrophobic (exosha amanzi) isakhi sofuzo sangaphezulurally ibhekisela endaweni ukuthi i-engeli yokuthintana phakathi kwamanzi nengaphezulu ingaphezu kwamadigri angu-150. Abantu bazi ukuthi i-superhydrophobic surface iphuma emaqabunga ezitshalo - i-lotus leaf surface, into "yokuzihlanza". Isibonelo, amaconsi amanzi angaginqika ukuze agingqike phezu kweqabunga le-lotus, ngisho noma amanye amanzi endle ethela eqabungeni, ngeke ashiye ibala emaqabunga. Izici ezinjalo zeqabunga le-lotus elingenabala zibizwa ngokuthi "ukuzihlanza" umphumela.

Umphumela weLotus - Isimiso se-Super hydrophobic

Nakuba abantu bebazi kusenesikhathi umphumela weqabunga le-lotus “wokuzihlanza”, kodwa abakwazanga ukuqonda imfihlo yendawo yamaqabunga e-lotus. Kuze kube yiminyaka yawo-1990, ososayensi ababili baseJalimane baqala ukubona ngesibonakhulu se-electron yokuskena, i-microstructure yeqabunga le-lotus, ukuthi umphumela "wokuzihlanza" ubangelwa i-micron mastoid kanye ne-lotus leaf surface wax ngaphezulu. Ngemva kwalokho, ososayensi bahlaziya ngokujulile ingaphezulu lesakhiwo se-lotus leaf micron futhi bathola ukuthi kune-nanostructures ku-lotus leaf surface mastoid, kuyilapho lesi sakhiwo esikabili se-micron kanye ne-nano-structure yizona zimbangela eziyinhloko "zokuzihlanza" indawo yeqabunga le-lotus.

Kungani indawo enjalo "enzima" ingakhiqiza i-superhydrophobic

Kundawo eqinile ye-hydrophobic, lapho ingaphezulu linomklamo omncane, omunye womoya "ungasuka" phakathi kwamanzi nezindawo eziqinile, okuholela emathonsini amaningi okuthintana komoya, kodwa ukuthintana okuqondile nezindawo eziqinile kakhulu. kuncipha. Njengoba ukungezwani okungaphezulu kwamaconsi amanzi amile ukuze indawo eqinile isondelene neyindilinga, i-engeli yokuxhumana ifinyelela kumadigri ayi-150, futhi amathonsi amanzi angaphezulu angagoqeka mahhala.

Ngisho nezinye zezinto ezingcolile ezingaphezulu, zizobe zigoqa amaconsi, ngakho ubuso buzoba nekhono "lokuzihlanza". Le ndawo ene-engeli yokuxhumana engaphezu kuka-150 degrees ibizwa ngokuthi “i-super-hydrophobic surface”, kanye ne-engeli yokuxhumana yofuzo.ral indawo ye-hydrophobic inkulu kune-90 degrees kuphela.

Emvelweniral umhlaba, ngaphandle kokuthi iqabunga le-lotus linamandla "wokuzihlanza", kukhona okunye okufana nerayisi, izitshalo ze-taro nezimpaphe njengezinyoni. , kanye nokuvimbela ukuhlasela kwamagciwane. Ngoba ngisho ne-pathogen ebusweni beqabunga, izogezwa. Ngakho-ke, ngisho nesitshalo se-lotus esikhula endaweni "engcolile" akulula ukugula, isizathu esibaluleke kakhulu kungenxa yaleli khono lokuzihlanza.
