Electrically conductive adhesive based on acrylate resin filled with silver plating graphite nanosheet
Review articleOpen access
Abstract:

AbstractSilver plating graphite nanosheet (Ag plating NanoG) is an effective approach to obtain the conductive filler with high electrical conductivity and moderate cost. Ag plating NanoG was prepared by electroless plating method using graphite nanosheet (NanoG) from expanded graphite (EG). Then a novel electrically conductive adhesive (ECA), comprising acrylate resin and Ag plating NanoG as conductive filler, was studied. The microstructures of Ag plating NanoG and ECA were studied by means of scanning electron microscopy (SEM), X-ray diffraction (XRD) and Fourier transmission infrared (FT-IR), transmission electron microscope (TEM). The results showed that the Ag plating NanoG was successfully developed and it was homogeneously dispersed in the acrylate resin. The electrical conductivity of the ECA increased to 2.60 × 10−2 S/cm and the 180° peel strength and shear strength remained at a high level when the content of the conductive filler was 40 wt%. From the thermogravimetric analysis, the ECA exhibited good thermal stability.
