Fa'amatalaga:
O mea fa'aletino ole silicon carbide nanowire:
tioata kupita, o se ituaiga tioata e tutusa ma taimane.O se tioata tasi-dimensional tasi ma le malosi maualuga ma foliga ava.O loʻo i ai le tele o mea faʻainisinia sili ona lelei e pei o le malosi maualuga ma le maualuga o le modulus, o se tasi lea o mea sili e faʻamalosia ma faʻamalosi.
O mea tau vaila'au o le silicon carbide nanowires:
La'ei tete'e, tete'e maualuga vevela, tete'e fa'apitoa fa'ate'ia, tete'e a'a, fa'avevela.
Fa'atonuga autu ole fa'aogaina ole silicon carbide nanowires:
1.SIC nanowires/ceramic matrix composites:SIC/TIC/WC/ALN/SI3N4/TIN/AL2O3/ZRO2/ZRB2 etc
2.SIC nanowires/metal matrix composites:AL/TI/NI etc
3.SIC nanowires/polymer fa'avae tu'ufa'atasi: nailoni/resin/rubber/plastic etc
Fa'asalalau ma fa'aopoopo le aofa'i o SiC Nanowires:
Fa'asalalau ma fa'aopoopo le aofa'i o SiC Nanowires (mo na'o fa'amatalaga)
Fautuaina ala fa'asalalauina: vai fa'a'ona, vai fa'amama, ethanol anhydrous, ethylene glycol
Fautuaina dispersant: Polyethylene imine (PEI), nonionic polyacry lamide (PAM), sodium pyrophosphate (SPP), lua 80, silicon compound soofaatasi sui, polyethylene glycol, sodium hexametaphosphate, sodium carboxymethyl cellulose (CMC), ma isi.
I totonu o mea masani matrix matrix composites, silicon carbide nanowires itiiti ifo i le 10wt% e masani ona faaopoopo.E tusa ai ma le faʻataʻitaʻiga faʻataʻitaʻiga, o le maualuga o le aofaʻi faʻaopoopo e le sili atu, e fesoʻotaʻi ma mea mata, tele meafaitino, vevela vevela, faʻaopoopoina talafeagai le aofaʻi e mafai ona maua ai le malosi sili ona lelei.
A maeʻa ona faʻafefiloi le SiC nanowire slurry ma le paʻu sima, faʻaauau pea ona taʻape mo le 1-12 itula.e fautuaina le fa'asalalauina o le vili vili po'o le fa'ainisinia.O le auala vili polo e faigofie e mafua ai ona malepe nanowires.
Afai e le lelei tele le faʻafefiloi o SiC nanowires ma mea matrix, o le sodium hexametaphosphate o le 1% mass o SiCNW (poʻo se vaega itiiti o le isopropanol/ethanol) e mafai ona faʻaopopo e fai ma faʻasalalauga e faʻaleleia ai le faʻafefiloi tutusa.
A maeʻa ona faʻasalalau, faʻamago ma faʻamago e tatau ona faia vave.Liligi le slurry i totonu o se vaʻa ma se vaega tele e faʻasalalau ai manifinifi, ma faʻateleina le vaega o le a faʻafefe ma faʻamama faigofie.Ole vevela ole fa'amamago ole 110-160℃.
