摘要：

The utilization of high-aspect-ratio silver nanobelts (NBs) is reported with the typical silver micro flakes to develop advanced electrical conductive adhesive (ECA) composite materials. Ag NBs (10-40 nm thick, 100-400 nm wide and 1-10 mu m long) were synthesized by chemical reduction of silver nitride. The incorporation of a small amount of the Ag NBs (NBs to flakes weight-ratio K = 0.03) into a conventional ECA with 60 wt% Ag micro flakes results in an electrical conductivity enhancement by 1300%. It is also found that adding a 2 wt% (K = 0.03) of the NBs into a conventional ECA with 80 wt% Ag flakes reduced the bulk resistivity to 3 x 10(-5) Omega . cm for the hybrid ECAs, which is comparable to that of a typical eutectic solder, showing great potential as an alternative electrical interconnect materials.
