Ngaba uyazi ukuba zeziphi izicelo zeiinanowires zesilivere?

I-nanomaterials ene-dimensional enye ibhekisa kubungakanani bomlinganiselo omnye wezinto eziphathekayo phakathi kwe-1 kunye ne-100nm.Iingqungquthela zetsimbi, xa zingena kwi-nanoscale, ziya kubonisa iziphumo ezikhethekileyo ezihluke kwizinto zetsimbi ze-macroscopic okanye ii-athomu zetsimbi enye, njengeempembelelo zesayizi encinci, i-interfaces, i-Effects, i-quantum size effects, i-macroscopic quantum tunneling effects, kunye ne-dielectric confinement effects.Ke ngoko, ii-nanowires zetsimbi zinamandla amakhulu okusebenza kwimimandla yombane, i-optics, i-thermals, i-magnetism kunye ne-catalysis.Phakathi kwazo, ii-nanowires zesilivere zisetyenziswa ngokubanzi kwi-catalysts, ukusabalalisa i-Raman eyongeziweyo, kunye nezixhobo ze-microelectronic ngenxa yombane obalaseleyo, ukufudumala kobushushu, ukumelana nomgangatho ophantsi, ukukhanya okuphezulu, kunye nokuhambelana kakuhle kwe-biocompatibility, iiseli zelanga zefilimu ezincinci, i-micro-electrodes, kunye ne-biosensor.

Iinanowires zesilivere ezifakwe kwi-catalytic field

I-nanomaterials yesilivere, ngakumbi i-nanomaterials yesilivere enobukhulu obufanayo kunye ne-aspect ratio ephezulu, ineempawu eziphezulu ze-catalytic.Abaphandi basebenzise i-PVP njenge-stabilizer yomhlaba kwaye balungiselela i-nanowires zesilivere ngendlela ye-hydrothermal kwaye bavavanya iipropati zabo ze-electrocatalytic oxygen reduction reaction (ORR) nge-cyclic voltammetry.Kwafunyaniswa ukuba i-nanowires yesilivere elungiselelwe ngaphandle kwe-PVP yayibaluleke kakhulu Ubuninzi be-ORR yangoku yonyuka, ibonisa amandla anamandla e-electrocatalytic.Omnye umphandi wasebenzisa indlela ye-polyol ngokukhawuleza kwaye kulula ukulungiselela i-nanowires zesilivere kunye ne-nanoparticles yesilivere ngokulawula inani le-NaCl (imbewu engathanga ngqo).Ngendlela enokwenzeka yokuskena, kwafunyaniswa ukuba i-nanowires zesilivere kunye ne-nanoparticles zesilivere zinemisebenzi eyahlukeneyo ye-electrocatalytic ye-ORR phantsi kweemeko ze-alkaline, ii-nanowires zesilivere zibonisa ukusebenza okungcono kwe-catalytic, kunye ne-nanowires yesilivere yi-electrocatalytic ORR Methanol inokumelana okungcono.Omnye umphandi usebenzisa i-nanowires zesilivere ezilungiselelwe yindlela ye-polyol njenge-electrode ye-catalytic yebhetri ye-lithium oxide.Ngenxa yoko, kwafunyaniswa ukuba i-nanowires zesilivere ezinomlinganiselo ophezulu we-aspect ratio zinendawo enkulu yokusabela kunye ne-oksijini eyomeleleyo yokunciphisa isakhono, kwaye yakhuthaza ukusabela kokubola kwebhetri ye-lithium oxide engaphantsi kwe-3.4 V, okukhokelela ekusebenzeni kombane okupheleleyo kwe-83.4% , ebonisa ipropathi egqwesileyo ye-electrocatalytic.

Iinanowires zesilivere ezifakwe kwindawo yombane

Iinanowires zesilivere ngokuthe ngcembe ziye zaba lugqaliselo lophando lwemathiriyeli ye-electrode ngenxa yokuhanjiswa kombane okugqwesileyo, ukumelana nomgangatho ophantsi kunye nokungafihlisi okuphezulu.Abaphandi balungiselela ii-electrode zesilivere ze-nanowire ezibonisa ukukhanya kunye nomphezulu ogudileyo.Kuvavanyo, ifilimu ye-PVP yayisetyenziswe njengoluhlu olusebenzayo, kwaye umphezulu wefilimu ye-nanowire yesilivere yayigutyungelwe yindlela yokudlulisa umatshini, eyaphucula ngokufanelekileyo ubuninzi bomhlaba we-nanowire.Abaphandi balungiselela ifilimu eguquguqukayo ye-transparent conductive eneempawu ze-antibacterial.Emva kokuba ifilimu ye-transparent conductive igobe amaxesha angama-1000 (i-radius egobayo ye-5mm), ukuxhathisa kwayo phezulu kunye nokuhanjiswa kokukhanya akuzange kutshintshe kakhulu, kwaye inokusetyenziswa ngokubanzi kwimiboniso ye-crystal yamanzi kunye nezinto ezinxitywayo.Izixhobo zombane kunye neeseli zelanga kunye nezinye iinkalo ezininzi.Omnye umphandi usebenzisa i-4 bismaleimide monomer (MDPB-FGEEDR) njenge-substrate yokufaka i-polymer conductive transparent elungiselelwe kwi-nanowires yesilivere.Uvavanyo lufumene ukuba emva kokuba i-polymer conductive ichetywe ngamandla angaphandle, i-notch yalungiswa phantsi kokufudumeza kwi-110 ° C, kwaye i-97% ye-conductivity yomhlaba inokubuyiselwa ngaphakathi kwemizuzu emi-5, kwaye indawo efanayo inokunqunyulwa ngokuphindaphindiweyo kwaye ilungiswe. .Omnye umphandi wasebenzisa i-nanowires zesilivere kunye neepolymers zeememori zemilo (SMPs) ukulungiselela i-polymer conductive ene-double-layer structure.Iziphumo zibonisa ukuba i-polymer ine-flexible egqwesileyo kunye ne-conductivity, inokubuyisela i-80% ye-deformation ngaphakathi kwe-5s, kunye ne-voltage kuphela i-5V, nokuba i-tensile deformation ifikelela kwi-12% igcina i-conductivity elungileyo, Ukongeza, i-LED Ukuvula amandla. yi-1.5V kuphela.Ipolymer eqhubayo inamandla okusebenza kwindawo yezixhobo zombane ezinxitywayo kwixesha elizayo.

Iinanowires zesilivere ezifakwe kwintsimi ye-optics

I-nanowires yesilivere ine-conductivity efanelekileyo yombane kunye ne-thermal, kwaye ukubonakala kwayo okucacileyo okuphezulu kusetyenziswe ngokubanzi kwizixhobo ezibonakalayo, iiseli zelanga kunye nezixhobo ze-electrode.I-electrode yesilivere ecacileyo ye-nanowire enendawo egudileyo ine-conductivity elungileyo kwaye ukuhanjiswa ukuya kuthi ga kwi-87.6%, enokusetyenziswa njengenye indlela ye-organic light-emitting diodes kunye nezixhobo ze-ITO kwiiseli zelanga.

Kulungiselelo lwemifuniselo yefilim eguquguqukayo ecacileyo, kujongwe ukuba ingaba inani lesilivere ye-nanowire deposition iya kuba nefuthe ekuhleni.Kwafunyaniswa ukuba njengoko inani lemijikelo ye-deposition ye-nanowires yesilivere yanda ukuya ku-1, 2, 3, kunye namaxesha e-4, ukungafihli kwale filimu ye-transparent conductive kwehla ngokuthe ngcembe ukuya kwi-92%, 87.9%, 83.1%, kunye ne-80.4%, ngokulandelanayo.

Ukongeza, ii-nanowires zesilivere zinokusetyenziselwa ukuthwala iplasma eyomeleziweyo kwaye zisetyenziswa ngokubanzi kuvavanyo lokuphucula umphezulu weRaman spectroscopy (SERS) ukufezekisa uchuku kunye nokungonakalisi.Abaphandi basebenzisa indlela eqhubekayo yokulungiselela i-crystal yesilivere ye-nanowire arrays kunye nomphezulu ogudileyo kunye nomlinganiselo ophezulu we-aspect ratio kwii-templates ze-AAO.

Iinanowires zesilivere ezifakwe kwintsimi yeenzwa

I-nanowires yesilivere isetyenziswa ngokubanzi kwintsimi yeenzwa ngenxa yokufudumala ukufudumala, ukuqhutyelwa kombane, ukuhambelana kwezinto eziphilayo kunye neempawu zokulwa ne-antibacterial.Abaphandi basebenzise i-nanowires zesilivere kunye ne-electrode elungisiweyo eyenziwe nge-Pt njenge-halide sensors ukuvavanya izinto ze-halogen kwinkqubo yesisombululo nge-cyclic voltammetry.Uvakalelo lwaluyi-0.059 kwi-200 μmol / L ~ 20.2 mmol / L Cl-solution.μA/(mmol•L), kuluhlu lwe-0μmol/L~20.2mmol/L Br- kunye ne-I-zisombululo, uvakalelo lwaluyi-0.042μA/(mmol•L) kunye ne-0.032μA/(mmol•L) ngokulandelelanayo.Abaphandi basebenzise i-electrode ye-carbon electrode eguquliweyo eyenziwe nge-nanowires zesilivere kunye ne-chitosan ukujonga i-As element emanzini enovakalelo oluphezulu.Omnye umphandi wasebenzisa i-nanowires zesilivere ezilungiselelwe indlela ye-polyol kwaye uguqule isikrini esiprintiweyo se-carbon electrode (SPCE) kunye nejeneretha ye-ultrasonic ukulungiselela inzwa ye-H2O2 engeyiyo-enzymatic.Uvavanyo lwe-polarographic lubonise ukuba inzwa ibonise impendulo ezinzileyo yangoku kwi-0.3 ukuya kwi-704.8 μmol / L H2O2, kunye novakalelo lwe-6.626 μA / (μmol • cm2) kunye nexesha lokuphendula le-2 kuphela.Ukongezelela, ngokusebenzisa iimvavanyo ze-titration zangoku, kufunyenwe ukuba i-H2O2 yokubuyisela i-sensor kwi-serum yabantu ifikelela kwi-94.3%, iqinisekisa ngakumbi ukuba le nzwa ye-H2O2 engeyiyo i-enzymatic ingasetyenziselwa ukulinganisa iisampuli zebhayoloji.
