Using the electroless plating method, the silver particles were successfully coated on the surface of graphite nanosheets (GNs) and carbon nanotubes (CNTs). Energydispersive spectrometer images showed that the content of silver was about 30-55 wt%, which were supported by the X-ray diffraction images and scanning electronmicroscopy images. Taking advantage of the 'Synergistic Effects' occurring between fillers with different morphologies, we were able to obtain silver-plated graphite nanosheets (Ag/GNs) and silver-plated carbon nanotubes (Ag/CNTs) filled polyacrylate-based electrically conductive adhesives (ECAs). Through the study, we found that the overall properties of the ECAs are optimum when the composite filler is at 30 wt% concentration, consisting of 21 wt% Ag/GNs and 9 wt% Ag/CNTs. Photograph of transmission electron microscope showed that the Ag/GNs and Ag/CNTs dispersed within the polymer matrix homogeneously. The conductivity of the ECAs reaches 8.71 S/cm and the shear strength is 0.47 MPa.
