Conductive zomatira ndi zomatira zapadera, zomwe zimapangidwa ndi utomoni ndi zopangira ma conductive (monga siliva, golide, mkuwa, faifi tambala, malata ndi ma aloyi, ufa wa kaboni, graphite, ndi zina), zomwe zitha kugwiritsidwa ntchito polumikizana ndi zida za microelectronic ndikupanga ma CD. njira zipangizo.

Pali mitundu yambiri ya zomatira za conductive.Malinga ndi particles zosiyanasiyana conductive, zomatira conductive akhoza kugawidwa mu zitsulo (golide, siliva, mkuwa, zotayidwa, nthaka, chitsulo, faifi tambala ufa) -zochokera ndi mpweya ofotokoza zomatira conductive.Pakati pa zomatira zomwe zili pamwambapa, zomatira za conductive zomwe zimapangidwa ndi ufa wa siliva zimakhala ndi ma conductivity abwino kwambiri, zomatira komanso kukhazikika kwamankhwala, sizikhala zokometsera zomatira muzomatira, komanso kuchuluka kwa makutidwe ndi okosijeni mumlengalenga kumakhalanso pang'onopang'ono ngakhale ndi oxidized, opangidwa siliva okusayidi akadali ndi conductivity wabwino.Chifukwa chake, pamsika, makamaka pazida zamagetsi zomwe zili ndi zofunikira zodalirika kwambiri, zomatira zokhala ndi ufa wasiliva monga ma conductive fillers ndi omwe amagwiritsidwa ntchito kwambiri.Posankha utomoni wa matrix, utomoni wa epoxy wakhala chisankho choyamba chifukwa cha kuchuluka kwake kwamagulu omwe akugwira ntchito, mphamvu zolumikizana kwambiri, kumamatira kwabwino, makina abwino kwambiri, komanso kusakanikirana kwabwino kwambiri.

Litisiliva ufaimawonjezedwa ku zomatira za epoxy ngati chodzaza chowongolera, njira yake yoyendetsera ndikulumikizana pakati pa ufa wasiliva.Pamaso pa zomatira conductive kuchiritsidwa ndi zouma, ufa siliva mu zomatira epoxy alipo paokha ndipo sasonyeza kukhudzana mosalekeza wina ndi mzake, koma si conductive ndi insulating boma.Pambuyo pochiza ndi kuyanika, chifukwa cha kuchiritsidwa kwa dongosolo, ufa wa siliva umagwirizanitsidwa wina ndi mzake mu mawonekedwe a unyolo kuti apange maukonde oyendetsa, kusonyeza conductivity.Pambuyo powonjezera ufa wa siliva ku zomatira za epoxy ndi ntchito yabwino (kuchuluka kwa toughening agent ndi machiritso ndi 10% ndi 7% ya epoxy resin mass, motero), ntchitoyo imayesedwa pambuyo pochiritsidwa.Malingana ndi deta yoyesera, pamene kuchuluka kwa siliva muzomatira kumawonjezeka, mphamvu ya resistivity imachepa kwambiri.Izi ndichifukwa choti ufa wa siliva ukakhala wochepa kwambiri, kuchuluka kwa utomoni m'dongosolo kumakhala kochulukirapo kuposa ufa wa siliva wa conductive, ndipo ufa wa siliva ndizovuta kukhudza kuti upangitse maukonde ogwira mtima, motero amawonetsa kukana kwakukulu. .Ndi kuchuluka kwa kudzaza kwa ufa wa siliva, kuchepa kwa utomoni kumawonjezera kukhudzana kwa ufa wa siliva, womwe umakhala wopindulitsa pakupanga netiweki ya conductive ndikuchepetsa mphamvu ya voliyumu.Pamene kuchuluka kwa kudzaza ndi 80%, mphamvu ya resistivity ndi 0.9 × 10-4Ω•cm, yomwe ili ndi conductivity yabwino, FYI.

Siliva ufandi chosinthika tinthu kukula (kuchokera 20nm-10um), akalumikidzidwa osiyana (ozungulira, pafupi-pherical, flake) ndi utumiki makonda kwa kachulukidwe, SSA, etc. zilipo.

Kuti mudziwe zambiri, chonde musazengereze kutilankhula nafe.
