Electrically conductive adhesive based on bismaleimide-triazine resin filled with microcoiled carbon fibers

Electrically conductive adhesive (ECA) was prepared with cyanate ester resin and bismaleimide resin formed bismaleimide‐triazine resin as the matrix, a γ‐glycidoxy propyl trimethoxy silane (KH‐560) as the coupling agent, and the carbon microcoils (CMCs) as the conducting filler. CMCs were synthesized by the catalytic decomposition of acetylene using nickel sulfide particles as the catalyst, which prepared by solvothermal method. The morphology and microstructure of CMCs were examined by scanning electron microscopy, Fourier transform infrared spectroscopy, and X‐ray diffraction. The electrical conductivity of the ECA increased to 3.16 × 10−2 S/cm. When the content of CMCs was 1.5 wt %, the shear strength between 25 and 200°C remained at a high value of 22.8 and 21.4 MPa, respectively. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
