Pou hangarau | 99% kai te mahi tonu te iwi i te electrospinning, kei te mahi kē rātau i tēnei...

wā:2019-11-27 Ngā Taunga:

He tukanga Electrospinning kei roto i te rongoā waerau, ko te refined-a-tiketike ngaohiko electrostatics. I te 80 tau mai i te advent me te whanaketanga o electrostatic kopae hangarau, te hangarau me nga taputapu e ahu whakamua ana. Electrostatic kopae nanomaterials kua whakamahia te rongonui i te pūkaha maretai kikonga, utukino utaina, dressings rongoā me ētahi atu āpure. Engari ko te tikanga hurihuri electrostatic noa ki te hanga i te hanganga whatunga i te nuinga o te muka nano kotahi-rahinga hei huihuinga whare, engari he raruraru hōrapa te tauira o te whare kōtuitanga, e anga ana ki te hiatonga o te uaua ki te pū i te hanganga mana, nanometer āhuatanga he uaua te pupuri inherent rāhuitanga, te aukati i nga rauemi mo te whakapai ake i nga mahi tono

 

I roto i nga tau tata nei, ngā mahere ahu--rua nanometer whatunga urutaunga tinana ka taea te whakawātea mō te hēnga o tētahi-mahere ahu-nanometer whatunga urutaunga tinana, te hēnga o te rawa me te taumahinga o te whaitaua rawa, a he waatea e whai kiko ana i roto i nga waahanga o te tiakitanga taiao, ngā pūrere hiko me te pūkaha koiora. I te tirohanga o tēnei tītohunga, i nanofiber te tīma rangahau i te ahorangi ding ipu me te academician yu jianyong o te kura o pueru, o te pueru hoki o te whare o donghua, he mea nui te haere ki te āpure o waerau matū tā me te tukatuka.

 

 

Ontology te tīma rangahau mā te arotau i ngā āhuahira rongoā, whakahaere i te Taylor aki koeko kutere te aratau whakatō, te whakatārewa i te āpure hiko ngaohiko i te tuari o te ngako tautau, ka hononga te whakamau e te regulating i te iti āpure hiko tuari, taputapu ngā ngako deformation/huri/pū mana o te huihuinga-whaiaro, te whakaata tākaka rangiwhiti o 10 ~ 40 nm rua-mahere ahu-nano te hanganga whatunga (tukutuku), a, ko te whakatinanatanga pai o te momo o te whakaritenga tukutuku, kua oti pai te whakarite i te PVDF, ROIROI, Waro, pēnei i te momo o pararopi/wairākau nanometer tukutuku TiO2 rawa.

 

 

 

Mahere ahu--rua nano hanganga whatunga kāore e taea te tuku i te puahaaha (200 ~ 300 nm), nui papa whenua (30 ~ 70 m2g - 1~, nga taonga nano penei i te porosity teitei (99.25%), me tino whakarei wettability o te kōwhiringa rawa, ngā āhuatanga me te pervious ki te mahinga marama, te wāhanga tukutuku pūngāwerewere i te rangi filtration, wē te wehenga, parenga koiora, ko ētahi atu āpure he whakaatu i ngā taupānga pūmanawa tino pai. Roto i a ratou, Tino Panui Tino Iti paninga PVDF nanometa me te tino hora te tuku (mārama >95%) ka taea te tātari i te PM ultra-pai 0.3 i te rangi me te filtration o 99.86%. Kua whakaritea me te ōkawa wē filtration rawa, Nanometer ngā wāhanga tukutuku pūngāwerewere he raupapa rarahi ake i te osmotic ngaorere me te tōtika filtration (99.92%) na tōna tino hydrophilic, permeability tere. I tua atu, te waipiro me te papanga paetukutuku pūngarau nano o TiO2 i whiwhi i muri i te waroatanga o te whakarakeatanga ranei te whakaatu i te whanonga hiko pai me nga tohu tiaki koiora., aua.

 

Te whakaaturanga mahi o nga momo paetukutuku umanga mokowhiti

 

Ko tenei mahi kaore i whakaarohia he momo hou o te hangarau miihini hiko hikoi hiko, i whakareri i nga rauemi papanga nano-whatunga e rua-nui me te mahinga nui me te mahi maha, engari i tukuna ano e ia he arahi me te tohutoro mo te hoahoa me te whanaketanga o nga whakatipuranga e whai ake nei mo nga taputapu tapahi-tihi-mitini-muka. Rangahau i te Electronetting Hāngai o te Tiketike - Nga Whakaaturanga Mahi -Kau i runga i te Kaha Takitahi - Huihui 2 ngā Nanoarchitectured ngā Whatunga d i whakaputaina mai i ngā Whakawhitinga take.
