Electrospinning inzira umo iyo polymer mhinduro inotambanudzwa uye inonatswa neakakwira voltage electrostatics. Mumakore makumi masere kubva pakuuya uye kuvandudzwa kweelectrostatic spinning tekinoroji, tekinoroji yakabatana nemidziyo yakafambira mberi zvikuru. Electrostatic spinning nanomaterials yakashandiswa zvakanyanya muinjiniya yetishu, kurodha zvinodhaka, zvipfeko zvekurapa uye mamwe minda. Asi yakajairika electrostatic kutenderera nzira yekuvaka network chimiro kazhinji ne-imwe-dimensional nano faibha sechinhu chekuvaka chakaungana, asi chivakwa chekuvaka chiri dambudziko rakapararira rekuenderera mberi, zvinotungamira kune yakaunganidzwa zvinhu yakatarisana yakaoma kunyatso kudzora chimiro, nanometer hunhu hwakaoma kuchengeta inherent kuganhurirwa, zvirambidzo zvakakomba pazvinhu zvakagadziridzwa mashandiro ekushandisa.

Mumakore achangopfuura, maviri-dimensional nanometer network zvimiro zvezvimiro zvinogona kugadzirisa hurema hweimwe-dimensional nanometer network zvimiro zvemidziyo, hurema hwezvinhu uye kushanda kwezvinhu zvekusimbisa, uye kuve netarisiro yakakura yekushandisa muminda yekuchengetedzwa kwezvakatipoteredza, zvigadzirwa zvemagetsi uye biological engineering. Nekuda kwechiitiko ichi, timu yekutsvagisa nanofiber inotungamirwa naProfessor Ding bin uye academician yu jianyong wepachikoro chemachira nemachira cheyunivhesiti yedonghua yakaita budiriro yakakosha mumunda wekugadzira zvinhu zvepolymer uye kugadzirisa.

Ontology timu yekutsvagisa nekugadzirisa maficha ekugadzirisa, kudzora iyo Taylor cone tip yakachaja jekiseni remvura modhi, kumisa mumhepo yakakwira magetsi emunda kugovera kweanochaja madonhwe masumbu, kubatanidzwa kunokonzereswa nekudzora muunganidzi wemagetsi emagetsi kugovera, inoshandisa iyo inochaja droplet deformation / shanduko / chaiyo kudzora kwekuzvibatanidza, maviri ~ dhiyamita netiweki dhiyamita ye10m40. (web), uye nekubudirira kwekuita kweakasiyana gadziriro yewebhu yezvigadzirwa zvemhando yebudiriro, parizvino yakagadziridzwa zvakabudirira kubva kuPVDF, PAN, Carbon, senge akasiyana organic/inorganic nanometer cobweb TiO2 zvinhu.

Maviri-dimensional nano network chimiro hachingopi iyo aperture (200 ~ 300 nm), yakakura chaiyo nzvimbo (30 ~ 70 m2g - 1), nano zvivakwa zvakaita seyakanyanya porosity (99.25%), uye zvakanyanya kunyorovesa kunyorova kwesarudzo yezvigadzirwa, michina zvivakwa uye kupenya kwekuita kwechiedza, iyo spider, spider webhu dhizaini, mhepo inodzivirira ine mhepo yekudzivirira, uye spider biological field uye mhepo inodzivirira. zvinogona kushandiswa. Pakati pazvo, Ultra-yakaonda PVDF nanometer spider web material ine high light transmittance (pachena> 95%) inogona kunyatso kusefa Ultra-yakatsetseka PM 0.3 mumhepo nekusefa kwakanaka kwe99.86%. Zvichienzaniswa neyakajairwa mvura yekusefa zvinhu, PAN nanometer spider web zvinhu zvine kurongeka kwehukuru hwepamusoro osmotic flux neyakafanana kusefa kushanda zvakanaka (99.92%) nekuda kweiyo super hydrophilic uye nekukurumidza permeability. Uye zvakare, kabhoni yakavakirwa uye TiO2 yakavakirwa nano spider webhu zvinhu zvakawanikwa mushure mecarbonization kana calcination inoratidzawo yakanakisa magetsi conductivity uye biological kuchengetedza maitiro, zvichiteerana.

Kuita kuratidzwa kweakasiyana nano spider web materials

Iri basa harina kungokurudzira rudzi rutsva rwe electrofluid dynamic machining tekinoroji, uye rakagadzirira maviri-dimensional nano-network magadzirirwo emidziyo ine yakakwirira kuita uye multifunction, asi zvakare yakapa nhungamiro uye referensi yekugadzira nekusimudzira chizvarwa chinotevera chekucheka-kumucheto nano-fiber zvinhu. Tsvagiridzo paDirect Electronetting yePamusoro - Performance Membranes -yakavakirwa paSelf - Yakaungana 2 d Nanoarchitectured Networks nyaya dzakaburitswa muNature Communications.
