Abstract
The surface conductive treatment is an essential step for piezoelectric composite material being application, but until now there are many issues remain to be solved. A conductive adhesion with low curable temperature, low resistivity and high welding spot adhesion strength was obtained for the conductive treatment of piezoelectric composite material. The welding spot adhesion strength was defined at first time. The conductive and adhesion properties were studied comparing with samples treated by ion sputtering. The conductive adhesive with curing agent of EDA has the lowest resistivity of 1.973 × 10−4 Ω cm and the highest welding spot adhesion strength of 7.93 MPa.
