Waba uzi ibisabwasilver nanowires?

Nanomateriali imwe-imwe yerekana ubunini bwurwego rumwe rwibintu biri hagati ya 1 na 100nm.Ibice by'ibyuma, iyo byinjiye muri nanoscale, bizerekana ingaruka zidasanzwe zitandukanye niz'ibyuma bya macroscopique cyangwa atome imwe y'icyuma, nk'ingaruka ntoya, intera, Ingaruka, ingano ya kwant, ingaruka za toni ya macroscopique, n'ingaruka zo gufunga dielectric.Kubwibyo, ibyuma bya nanowire bifite imbaraga nyinshi zo gukoresha mubice byamashanyarazi, optique, thermals, magnetism na catalizike.Muri byo, nanowire ya silver ikoreshwa cyane muri catalizator, gukwirakwiza Raman ikwirakwiza hejuru, hamwe nibikoresho bya elegitoroniki kubera amashanyarazi meza cyane, amashanyarazi, ubushyuhe buke, kutagaragara neza, hamwe na biocompatibilité nziza, selile yizuba ya firime, micro-electrode, na biosensor.

Ifeza ya nanowire ikoreshwa murwego rwa catalitiki

Ifeza ya nanomateriali, cyane cyane ifeza ya nanomateriali ifite ubunini bumwe hamwe nikigereranyo kinini, ifite ibintu byinshi bya catalitiki.Abashakashatsi bifashishije PVP nka stabilisateur yubutaka kandi bategura nanowire ya silver hakoreshejwe hydrothermal kandi bapima imitungo ya electrocatalytic ya ogisijeni yo kugabanya (ORR) ikoresheje voltammetry.Byagaragaye ko nanowire ya silver yateguwe idafite PVP yari igaragara cyane Ubucucike bwa ORR buriho bwiyongereye, bwerekana imbaraga za electrocatalytic.Undi mushakashatsi yakoresheje uburyo bwa polyol kugirango yihute kandi byoroshye gutegura nanowire ya silver na nanoparticles ya silver agenga ingano ya NaCl (imbuto itaziguye).Ukoresheje uburyo bushoboka bwo gusikana, byagaragaye ko nanowire ya silver na nanoparticles ifite ibikorwa bitandukanye bya electrocatalytic ya ORR mubihe bya alkaline, nanowire ya silver yerekana imikorere myiza ya catalitiki, naho nanowire ya silver ni electrocatalytic ORR Methanol ifite imbaraga zo guhangana neza.Undi mushakashatsi akoresha nanowire ya silver yateguwe nuburyo bwa polyol nka electrode ya catalitiki ya batiri ya lithium oxyde.Kubera iyo mpamvu, byagaragaye ko nanowire ya silver ifite igipimo kinini cyo hejuru ifite ahantu hanini cyane hamwe nubushobozi bukomeye bwo kugabanya ogisijeni, kandi igateza imbere kwangirika kwa batiri ya lithium oxyde iri munsi ya 3.4 V, bigatuma amashanyarazi yose hamwe agera kuri 83.4% , yerekana umutungo mwiza wa electrocatalytic.

Ifeza nanowire ikoreshwa mumashanyarazi

Ifeza ya nanowire yahindutse buhoro buhoro ubushakashatsi bwibikoresho bya electrode bitewe nubushobozi bwiza bwamashanyarazi, guhangana nubutaka buke no gukorera mu mucyo mwinshi.Abashakashatsi bateguye electrode ya silver nanowire ibonerana ifite ubuso bunoze.Mu bushakashatsi, firime ya PVP yakoreshejwe nk'urwego rukora, kandi hejuru ya firime ya silver nanowire yari itwikiriwe nuburyo bwo guhererekanya imashini, byazamuye neza ububobere bwa nanowire.Abashakashatsi bateguye firime yoroheje ikora neza kandi ifite antibacterial.Nyuma yuko firime yimyitwarire iboneye yunamye inshuro 1000 (radiyo igoramye ya 5mm), irwanya ubuso bwayo hamwe nogukwirakwiza urumuri ntabwo byahindutse kuburyo bugaragara, kandi birashobora gukoreshwa cyane mumazi ya kirisiti yerekana no kwambara.Ibikoresho bya elegitoronike hamwe nizuba nizindi nzego nyinshi.Undi mushakashatsi akoresha 4 bismaleimide monomer (MDPB-FGEEDR) nka substrate kugirango ashyiremo polymer ikora neza iboneka muri nanowire ya silver.Ikizamini cyerekanye ko nyuma y’uko polimeri ikora kogosha n’imbaraga zo hanze, ikibanza cyarasanwe hashyushye kuri 110 ° C, kandi 97% by’ubuso bw’ubutaka bushobora kugarurwa mu minota 5, kandi umwanya umwe ushobora gutemwa inshuro nyinshi no gusanwa .Undi mushakashatsi yakoresheje nanowire ya silver no gushushanya polymers yibuka (SMPs) kugirango ategure polymer ikora hamwe nuburyo bubiri.Ibisubizo byerekana ko polymer ifite imiterere ihindagurika kandi ikora neza, irashobora kugarura 80% ya deformasiyo muri 5s, hamwe na voltage 5V gusa, nubwo deformile tensile igera kuri 12% iracyakomeza gukora neza, Byongeye, LED Ubushobozi bwo gufungura ibintu ni 1.5V gusa.Imiyoboro ya polymer ifite imbaraga nyinshi zo gukoresha mubijyanye nibikoresho bya elegitoroniki byambara mugihe kizaza.

Ifeza ya nanowire ikoreshwa murwego rwa optique

Ifeza ya nanowire ifite amashanyarazi meza nubushyuhe, kandi ubwisanzure bwihariye bwihariye bwakoreshejwe cyane mubikoresho bya optique, selile izuba hamwe nibikoresho bya electrode.Ifeza ya nanowire ya electrode ibonerana ifite ubuso bunoze ifite imiyoboro myiza kandi ihererekanyabubasha rigera kuri 87,6%, rishobora gukoreshwa nkuburyo bwa diode itanga urumuri kama nibikoresho bya ITO mumirasire y'izuba.

Mugutegura ibizamini bya firime byoroshye byoroshye, hasuzumwe niba umubare wa silver nanowire wabitswe wagira ingaruka kumucyo.Byagaragaye ko uko umubare w’ibizunguruka bya silver nanowire wiyongereye ugera ku nshuro 1, 2, 3, na 4, gukorera mu mucyo iyi filime ikora mu mucyo byagabanutse buhoro buhoro kugera kuri 92%, 87.9%, 83.1%, na 80.4%.

Byongeye kandi, nanowire ya feza irashobora kandi gukoreshwa nkubwikorezi bwa plasma itwara hejuru kandi ikoreshwa cyane mubutaka bwongera ibizamini bya Raman spectroscopy (SERS) kugirango bigerweho neza kandi bidafite ishingiro.Abashakashatsi bifashishije uburyo buhoraho bushoboka kugirango bategure kristu imwe ya silver ya nanowire igizwe nubuso bunoze kandi bugereranije cyane murwego rwa AAO.

Ifeza ya nanowire ikoreshwa murwego rwa sensor

Ifeza ya nanowire ikoreshwa cyane mubijyanye na sensor bitewe nubushyuhe bwiza bwayo, amashanyarazi, biocompatibilité na antibacterial.Abashakashatsi bifashishije nanowire ya silver na electrode yahinduwe ikozwe muri Pt nka sensor ya halide kugirango bagerageze ibintu bya halogene muri sisitemu yo gukemura na voltammetry cyclic.Ibyiyumvo byari 0.059 muri 200 μ mol / L ~ 20.2 mmol / L Cl-igisubizo.μA / (mmol • L), mu ntera ya 0μmol / L ~ 20.2mmol / L Br- na I-ibisubizo, ibyiyumvo byari 0.042μA / (mmol • L) na 0.032μA / (mmol • L).Abashakashatsi bifashishije electrode ya karubone iboneye ikozwe muri silver nanowire na chitosan kugirango bakurikirane As element mumazi hamwe na sensibilité nyinshi.Undi mushakashatsi yakoresheje nanowire ya silver yateguwe nuburyo bwa polyol hanyuma ahindura ecran yacapishijwe karubone electrode (SPCE) hamwe na generator ya ultrasonic kugirango ategure sensor ya H2O2 idafite imisemburo.Ikizamini cya polarografiya cyerekanye ko sensor yerekanaga igisubizo gihamye kiri hagati ya 0.3 kugeza 704.8 μ mol / L H2O2, hamwe na sensibilité ya 6.626 μA / (μmol • cm2) nigihe cyo gusubiza cya s 2 gusa.Byongeye kandi, binyuze mu bizamini bya titre biriho ubu, byagaragaye ko gukira kwa sensor ya H2O2 muri serumu yumuntu bigera kuri 94.3%, bikomeza kwemeza ko iyi sensor ya H2O2 idafite imisemburo ishobora gukoreshwa mugupima ingero z’ibinyabuzima.
