Kev ntsuas hluav taws xob ntawm electroplated conductive roj hmab rau hluav taws xob cua sov raj

Kev ntsuas hluav taws xob ntawm electroplated conductive roj hmab rau hluav taws xob cua sov raj

Performance characterization

Kev tsom xam X-ray diffraction (XRD) ntawm fibers tau ua los ntawm D/MAX-3C X-ray diffractometer (Nyiv); Qhov chaw morphology tau pom siv QUAN-TA200 scanning electron microscope (FeiCompany, USA);

Kev ntsuas kev ua tau zoo ntawm cov nyiaj plated conductive fibers [6]: Ib qho nyiaj ntawm cov khoom siv hluav taws xob tau muab tso rau hauv 1cm txoj kab uas hla yas lub tog raj kheej, nrog kub plated electrodes nrog tib txoj kab uas hla ntawm ob sab. Lub tog raj kheej yog muab tso rau ntsug, thiab lub cev hnyav (5kg) yog nias rau saum, thiab ntsuas qhov tsis kam ntawm ob lub electrodes. Vim muaj huab cua, qhov chaw sib cuag tiag tiag ntawm cov fiber ntau thiab cov phaj electrode tsis yog S, tab sis SF. Volume resistivity ntawm fibers (ρ v) xam raws li nram no:

Hauv cov mis, VE yog qhov tseeb ntim ntawm fiber ntau (cm3); VF yog qhov ntim ntawm lub tog raj kheej (cm3). M yog qhov loj ntawm cov qauv, S yog thaj tsam ntawm lub phaj electrode, thiab l yog qhov kev ncua deb ntawm cov electrode daim hlau Yog qhov fiber ntau ntom (txhua tus paub). F yog qhov sau degree, uas yog 0.23 hauv qhov system no.

Kev ntsuas kev ua tau zoo ntawm cov roj hmab conductive: 107 kua silicone roj hmab tau siv, nrog ethyl orthosilicate ua tus neeg sawv cev crosslinking thiab dibutyltin bisilicate ua tus catalyst. Tom qab ntxiv tus neeg sawv cev kho, nws tau sib npaug nrog cov nyiaj plated conductive fiber, molded, thiab kho hauv tsev cog khoom rau 24 teev, thiab tom qab ntawd ua rau 28mm × 28mm × Ntsuas tus nqi tsis kam ntawm 12mm lub tog raj kheej thiab suav cov resistivity raws li. rau equation (3) (ρ)

Hauv cov qauv, R yog qhov tsis kam ntawm cov qauv, d yog txoj kab uas hla ntawm lub tog raj kheej qauv, thiab L yog qhov ntev ntawm lub tog raj kheej.
