I-Electrospinning yinkqubo apho isisombululo se-polymer soluliwe kwaye sicocwe yi-electrostatics ephezulu yombane. Kwiminyaka engama-80 ukususela ekufikeni kunye nophuhliso lwetekhnoloji ye-electrostatic spinning, itekhnoloji ehambelanayo kunye nezixhobo zenze inkqubela enkulu. I-Electrostatic spinning nanomaterials isetyenziswe ngokubanzi kubunjineli bezicubu, ukulayishwa kweziyobisi, ukunxitywa kwezonyango kunye nezinye iinkalo. Kodwa i-electrostatic spinning indlela eqhelekileyo yokwakha isakhiwo sothungelwano ngokuqhelekileyo yifayibha enye-dimensional nano njengeyunithi yokwakha edityanisiweyo, kodwa iyunithi yokwakha yingxaki enkulu yokuqhubekeka okungahambi kakuhle, okukhokelela kwizinto ezihlangeneyo ezijongene nobunzima kwisakhiwo solawulo oluchanekileyo, iimpawu ze-nanometer kunzima gcina umda wendalo, izithintelo ezinzima kwizinto eziphuculweyo zokusebenza kwesicelo

Kwiminyaka yakutshanje, izixhobo zesakhiwo se-nanometer ye-nanometer ene-dimensional-dimensional inokwenza iziphene zesakhiwo se-nanometer ye-nanometer ene-dimensional network, iziphene zezixhobo kunye nokusebenza kwezixhobo zokuqinisa, kunye nethemba elibanzi lesicelo kwiinkalo zokukhusela indalo, izixhobo zombane kunye nobunjineli bebhayoloji. Ngenxa yesi siganeko, iqela lophando lwe-nanofiber elikhokelwa ngunjingalwazi u-ding bin kunye ne-academician yu jianyong wesikolo se-textile kunye ne-textile ye-donghua yeyunivesithi lenze inkqubela phambili ebalulekileyo kwinkalo yokwenziwa kwemathiriyeli ye-polymer kunye nokucubungula.

Iqela lophando lwe-Ontology ngokuphucula iimpawu zesisombululo, lawula imowudi ye-Taylor cone ehlawuliswe imowudi yokutofa ulwelo, ukunqunyanyiswa kumandla ombane aphezulu osasazo lwendawo yombane yamaqela amathontsi ahlawulweyo, ukudityaniswa okubangelwe ngokulawula umqokeleli kwindawo yombane omncinci, kusebenzisa i-droplet deformation/utshintsho. / ulawulo oluchanekileyo lokuzihlanganisa, i-fiber diameter ye-10 ~ 40 nm ye-nano network ye-dimensional-dimensional (iwebhu), kunye nokuphunyezwa ngempumelelo kweentlobo ezahlukeneyo zokulungiswa kwewebhu kwezinto eziluhlaza zophuhliso olusebenzayo, okwangoku lulungiswe ngempumelelo ukusuka. I-PVDF, i-PAN, i-Carbon, efana neentlobo ze-organic/inorganic nanometer cobweb TiO2.

Isakhiwo senethiwekhi ye-nano enemigangatho emibini ayiniki nje indawo yokuvula (200 ~ 300 nm), indawo enkulu yendawo ethile (30 ~ 70 m2g - 1), iipropati ze-nano ezifana ne-porosity ephezulu (99.25%), kunye nokuphucula ngokubonakalayo ukumanzi okukhethiweyo. izixhobo, iipropati oomatshini kunye pervious ukusebenza ukukhanya, imathiriyeli yewebhu yesigcawu ekuhluzweni emoyeni, ukwahlula ulwelo, ukhuseleko lwebhayoloji, kunye nezinye iinkalo zibonise izicelo ezibalaseleyo. Phakathi kwazo, i-ultra-thin PVDF nanometer spider web material ene-highlight transmittance (transmittance> transparent>95%) inokucoca ngokufanelekileyo i-ultra-fine PM 0.3 emoyeni ngokusebenza kakuhle kokucoca kwe-99.86%. Xa kuthelekiswa nezinto eziqhelekileyo zokuhluza ulwelo, imathiriyeli yewebhu yesigcawu ye-PAN ine-odolo yobukhulu obuphezulu be-osmotic flux kunye nempumelelo efanayo yokuhluza (99.92%) ngenxa ye-super hydrophilic kunye ne-permeability ekhawulezayo. Ukongeza, i-carbon based kunye ne-TiO2 esekelwe kwi-nano spider web materials ezifunyenwe emva kwe-carbonization okanye i-calcination nazo zibonisa ukuqhutyelwa kombane okugqwesileyo kunye neempawu zokukhusela eziphilayo, ngokulandelanayo.

Umboniso wentsebenzo yezinto ezahlukeneyo ze-nano spider web

Lo msebenzi awuphakamisanga kuphela uhlobo olutsha lwetekhnoloji ye-electrofluid dynamic machining technology, kwaye ulungiselele izixhobo zesakhiwo se-nano-network enamacala amabini kunye nokusebenza okuphezulu kunye nokusebenza okuninzi, kodwa kwakhona unikeze isikhokelo kunye nesalathiso soyilo kunye nophuhliso lwesizukulwana esilandelayo se-nano-edge. -ifayibha izinto. Uphando kwi-Electronetting Direct of High-Performance Membranes-based on the Self-Assembled 2 d Nanoarchitectured Networks imiba epapashwe kwiNdalo yoNxibelelwano.
