Kodi mukudziwa zomwe ntchito zasilver nanowires?
One-dimensional nanomaterials amatanthawuza kukula kwa gawo limodzi lazinthu zomwe zili pakati pa 1 ndi 100nm.Zitsulo zachitsulo, zikalowa mu nanoscale, zidzawonetsa zotsatira zapadera zomwe zimakhala zosiyana ndi zitsulo zazikulu kapena maatomu achitsulo amodzi, monga zotsatira zazing'ono, mawonekedwe, Zotsatira, zotsatira za kukula kwa quantum, macroscopic quantum tunneling effects, ndi zotsatira za dielectric confinement.Chifukwa chake, ma nanowires achitsulo ali ndi kuthekera kwakukulu kogwiritsa ntchito magetsi, optics, thermals, magnetism ndi catalysis.Pakati pawo, ma nanowires asiliva amagwiritsidwa ntchito kwambiri muzothandizira, kufalikira kwa Raman pamwamba, ndi zida za microelectronic chifukwa cha kayendedwe kabwino ka magetsi, kutentha kwa kutentha, kukana kutsika kwapansi, kuwonekera kwakukulu, ndi kuyanjana kwabwino, filimu yopyapyala ya dzuwa, micro-electrodes, ndi biosensor.
Silver nanowires amagwiritsidwa ntchito mu gawo lothandizira
Silver nanomatadium, makamaka nanomaterials zasiliva zokhala ndi kukula kofananira komanso mawonekedwe apamwamba, zimakhala ndi zopatsa mphamvu zambiri.Ofufuzawa adagwiritsa ntchito PVP ngati stabilizer yapamtunda ndikukonza ma nanowires asiliva pogwiritsa ntchito njira ya hydrothermal ndikuyesa mawonekedwe awo a electrocatalytic oxygen reduction reaction (ORR) ndi cyclic voltammetry.Zinapezeka kuti siliva nanowires okonzeka popanda PVP anali kwambiri The ORR panopa kachulukidwe chawonjezeka, kusonyeza mphamvu electrocatalytic mphamvu.Wofufuza wina adagwiritsa ntchito njira ya polyol kuti akonzekere mwachangu komanso mosavuta ma nanowires asiliva ndi ma nanoparticles asiliva powongolera kuchuluka kwa NaCl (mbewu yosalunjika).Ndi liniya kuthekera kupanga sikani njira, anapeza kuti siliva nanowires ndi nanoparticles siliva ndi osiyana electrocatalytic zochita kwa ORR pansi zinthu zamchere, nanowires siliva amasonyeza bwino chothandizira ntchito, ndi nanowires siliva ndi electrocatalytic ORR Methanol ali kukana bwino.Wofufuza wina amagwiritsa ntchito ma nanowires asiliva okonzedwa ndi njira ya polyol monga electrode catalytic ya batri ya lithiamu oxide.Zotsatira zake, zidapezeka kuti ma nanowires asiliva okhala ndi chiŵerengero chachikulu ali ndi gawo lalikulu komanso mphamvu yochepetsetsa ya okosijeni, ndipo amalimbikitsa kuwonongeka kwa batire ya lithiamu okusayidi pansi pa 3.4 V, zomwe zimapangitsa kuti pakhale mphamvu yamagetsi ya 83,4% , kusonyeza katundu wabwino kwambiri wa electrocatalytic.
Nanowires zasiliva zogwiritsidwa ntchito pamagetsi
Silver nanowires pang'onopang'ono yakhala malo opangira ma elekitirodi ofufuza chifukwa cha kuwongolera kwawo kwamagetsi, kutsika kwapamtunda komanso kuwonekera kwambiri.Ochita kafukufuku anakonza maelekitirodi a siliva a nanowire okhala ndi malo osalala.Poyesera, filimu ya PVP idagwiritsidwa ntchito ngati wosanjikiza, ndipo pamwamba pa filimu ya nanowire ya siliva idaphimbidwa ndi njira yosinthira makina, yomwe idakulitsa bwino kuuma kwa nanowire.Ofufuzawa adakonza filimu yosinthika yowoneka bwino yokhala ndi antibacterial properties.Pambuyo mandala conductive filimu anapindika 1000 nthawi (kupindika utali wozungulira wa 5mm), kukana kwake pamwamba ndi transmittance kuwala sanasinthe kwambiri, ndipo angagwiritsidwe ntchito kwambiri mawonetseredwe madzi galasi ndi kuvala.Zipangizo zamagetsi ndi ma cell a solar ndi magawo ena ambiri.Wofufuza wina amagwiritsa ntchito 4 bismaleimide monomer (MDPB-FGEEDR) ngati gawo lapansi kuti atseke polima yowoneka bwino yokonzedwa kuchokera ku nanowires zasiliva.Mayesowo adapeza kuti polima atametedwa ndi mphamvu yakunja, mphakoyo idakonzedwanso potentha pa 110 ° C, ndipo 97% ya ma conductivity apamwamba amatha kubwezeredwa mkati mwa mphindi 5, ndipo malo omwewo amatha kudulidwa mobwerezabwereza ndikukonzedwa. .Wofufuza wina adagwiritsa ntchito ma nanowires asiliva ndi ma polima okumbukira mawonekedwe (SMPs) kukonza polima yochititsa chidwi yokhala ndi magawo awiri.Zotsatira zimasonyeza kuti polima ali kusinthasintha kwambiri ndi madutsidwe, akhoza kubwezeretsa 80% ya mapindikidwe mkati 5s, ndi voteji yekha 5V, ngakhale mapindikidwe wamakokedwe kufika 12% akadali madutsidwe wabwino, Komanso, LED The kuyatsa angathe. ndi 1.5V yokha.Polima ya conductive ili ndi kuthekera kwakukulu kogwiritsa ntchito pazida zamagetsi zotha kuvala mtsogolo.
Silver nanowires amagwiritsidwa ntchito m'munda wa Optics
Silver nanowires ali ndi magetsi abwino komanso matenthedwe, ndipo kuwonekera kwawo kwapadera kwagwiritsidwa ntchito kwambiri pazida zowonera, ma cell a solar ndi zida za electrode.The mandala siliva nanowire elekitirodi ndi yosalala pamwamba madutsidwe wabwino ndi transmittance mpaka 87.6%, amene angagwiritsidwe ntchito m'malo organic kuwala-emitting diode ndi zipangizo ITO m'maselo dzuwa.
Pokonzekera zoyeserera zosinthika zowoneka bwino zamakanema, zidafufuzidwa kuti ngati kuchuluka kwa siliva nanowire kuyika kungakhudze kuwonekera.Zinapezeka kuti chiwerengero cha mafunsidwe mkombero wa nanowires siliva kuchuluka kwa 1, 2, 3, ndi 4 nthawi, mandala filimuyi mandala conductive pang'onopang'ono utachepa kwa 92%, 87,9%, 83.1%, ndi 80,4%, motero.
Kuphatikiza apo, ma nanowires asiliva amathanso kugwiritsidwa ntchito ngati chonyamulira chowonjezera cha plasma ndipo amagwiritsidwa ntchito kwambiri pakuyesa kwapamtunda kwa Raman spectroscopy (SERS) kuti akwaniritse kuzindikira komanso kusawononga.Ofufuzawa adagwiritsa ntchito njira yokhazikika yokonzekera ma crystal silver nanowire arrays okhala ndi mawonekedwe osalala komanso chiŵerengero chapamwamba pazithunzi za AAO.
Silver nanowires amagwiritsidwa ntchito m'munda wa masensa
Silver nanowires amagwiritsidwa ntchito kwambiri m'munda wa masensa chifukwa cha kutentha kwawo kwabwino, kuyendetsa magetsi, biocompatibility ndi antibacterial properties.Ofufuzawo adagwiritsa ntchito ma nanowires asiliva ndi ma elekitirodi osinthidwa opangidwa ndi Pt ngati masensa a halide kuyesa zinthu za halogen mu njira yothetsera vuto ndi cyclic voltammetry.Kumverera kunali 0.059 mu 200 μmol/L ~ 20.2 mmol/L Cl-solution.μA/(mmol•L), mumitundu ya 0μmol/L~20.2mmol/L Br- ndi I-mayankho, zomverera zinali 0.042μA/(mmol•L) ndi 0.032μA/(mmol•L) motsatana.Ofufuzawa adagwiritsa ntchito ma electrode owoneka bwino a kaboni opangidwa ndi nanowires zasiliva ndi chitosan kuwunika As element m'madzi yokhala ndi chidwi kwambiri.Wofufuza wina adagwiritsa ntchito ma nanowires asiliva okonzedwa ndi njira ya polyol ndikusintha chinsalu chosindikizidwa cha carbon elekitirodi (SPCE) ndi jenereta ya akupanga kuti akonze sensa yopanda enzymatic H2O2.Kuyesa kwa polarographic kunasonyeza kuti sensayo inasonyeza kuyankha kosasunthika pakali pano mumtundu wa 0.3 mpaka 704.8 μmol / L H2O2, ndi chidziwitso cha 6.626 μA / (μmol• cm2) ndi nthawi yoyankha ya 2 s.Kuphatikiza apo, kudzera mu mayeso apano a titration, zapezeka kuti kuchira kwa sensa ya H2O2 mu seramu yamunthu kumafika 94.3%, kutsimikiziranso kuti sensa iyi yopanda enzymatic H2O2 ingagwiritsidwe ntchito poyezera zitsanzo zamoyo.
