    摘要:

    研究了銀片粒徑對折疊前后銀漿電導(dǎo)率的影響。采用不同粒徑的片狀銀制備了具有良好導(dǎo)電性能的低溫固化耐折導(dǎo)電銀漿料，將銀漿網(wǎng)印在聚酰亞胺基板上，在140 ℃下燒結(jié)形成網(wǎng)印電路。用微歐姆計檢測了印刷電路的電阻率，對印刷銀電路折疊前后的電阻變化進(jìn)行了檢測，并用掃描電鏡對其表面形貌進(jìn)行了研究，分析了導(dǎo)電機(jī)理。結(jié)果表明，小片Ag作為未連接薄片之間的橋梁，在折疊后填補(bǔ)了空白，形成導(dǎo)電網(wǎng)絡(luò)，提高了折疊后的銀漿導(dǎo)電性能。

    Abstract:

    The influence of Ag flake size on the electrical conductivity of silver pastes before and after folding was investigated. The low-temperature curing conductive silver pastes with good electrical conductivity after folding were fabricated using Ag flake with different flake sizes. Then the silver pastes were screen-printed on the polyimide substrate and sintered at 140 °C to form the circuits. The electrical resistivity of the printed circuits was detected by micro-ohmmeter. In order to measure the flexibility of Ag circuits, the variance of electrical resistivity of Ag circuits was detected after they were folded. The surface morphology of the folded Ag circuits was observed by the scanning electron microscopy. The conductive mechanism was analyzed. The results show that the small Ag flakes can act as the bridge between the unconnected flakes and fill the gaps after the circuits are folded, which forms the conductive networks, thereby improving the electrical conductivity after folding.
