Kudzitchinjiriza Zochita za Super Hydrophobic Surface

Kunyowa ndi chinthu chofunikira kwambiri chapamwamba, chomwe chimatsimikiziridwa ndi kapangidwe ka mankhwala ndi morphology ya pamwamba. Super-hydrophilic ndi super hydrophobic Mawonekedwe apamwamba ndizomwe zili m'maphunziro owononga. Jini yapamtunda ya superhydrophobic (yoletsa madzi).rally amatanthauza pamwamba kuti ngodya yolumikizana pakati pa madzi ndi pamwamba ndi yayikulu kuposa madigiri 150. Zomwe anthu amadziwa kuti superhydrophobic pamwamba imachokera ku masamba a zomera - tsamba la lotus, "kudziyeretsa" chodabwitsa. Mwachitsanzo, madontho amadzi amatha kugubuduza pamwamba pa tsamba la lotus, ngakhale madzi ena achimbudzi atathira pamasamba, sasiya banga pamasamba. Makhalidwe otere a masamba a lotus amatchedwa "kudziyeretsa".

Mphamvu ya Lotus - Super hydrophobic mfundo

Ngakhale anthu adziwa kale kwambiri za masamba a lotus "kudziyeretsa", koma sanathe kumvetsetsa chinsinsi cha tsamba la lotus. Mpaka zaka za m'ma 1990, asayansi awiri aku Germany adawona koyamba pogwiritsa ntchito maikulosikopu ya electron, microstructure ya tsamba la lotus, kuti "kudziyeretsa" kumadza chifukwa cha micron mastoid ndi lotus tsamba pamwamba sera. Pambuyo pake, Asayansi adasanthula mozama pamwamba pa tsamba la lotus tsamba la micron ndipo adapeza kuti pali nanostructures mu lotus leaf surface mastoid, pomwe mawonekedwe apawiri a micron ndi nano-structure ndizomwe zimayambitsa "kudziyeretsa" tsamba la lotus.

Chifukwa chiyani malo "ovuta" oterewa amatha kupanga superhydrophobic

Pamalo olimba a hydrophobic, pomwe pamwamba pamakhala tinthu tating'onoting'ono, mpweya wina "umakhala" pakati pa madzi ndi malo olimba, zomwe zimapangitsa madontho amadzi kukhudzana kwambiri ndi mpweya, koma kukhudzana mwachindunji ndi malo olimba kwambiri. amachepetsa. Popeza kuthamanga pamwamba madzi m'malovu mu mawonekedwe kuti roughened pamwamba pafupi ozungulira, kukhudzana ngodya ndi madigiri 150, ndi madontho a madzi pamwamba akhoza kukhala omasuka yokulungira.

Ngakhale ndi zinthu zina zonyansa pamwamba, iwo adzakhala akugudubuza madontho kutali, kotero pamwamba adzakhala ndi mphamvu "kudziyeretsa". Pamwambapa wokhala ndi ngodya yokulirapo kuposa madigiri 150 amatchedwa "super-hydrophobic surface", ndi mbali yolumikizana ya jini.ral hydrophobic pamwamba ndi wamkulu kuposa madigiri 90.

Mu chilengedweral dziko, kupatula kuti tsamba la lotus liri ndi mphamvu "yodziyeretsa", palinso ena monga mpunga, zomera za taro ndi nthenga monga mbalame. , komanso kupewa kuukira kwa tizilombo toyambitsa matenda. Chifukwa ngakhale tizilombo toyambitsa matenda pamwamba pa tsamba, tidzatsukidwa. Choncho monga chonchi, ngakhale chomera cha lotus chomwe chimamera m'malo "akuda" sizovuta kudwala, chifukwa chofunika kwambiri ndi chifukwa cha kudziyeretsa kumeneku.
