Characterization and conductive property of polyurushiol/silver conductive coatings prepared under UV irradiation

Polyurushiol/silver (PU/Ag) composite conductive coatings were prepared from urushiol and AgNO3 under UV irradiation by using in situ radical reduction approach. The effects of the silver nitrate loading and the irradiation time on the surface resistivity of polyurushiol/silver (PU/Ag) composite films were investigated. The result from XRD analysis showed that the formation of Ag particles, and the surface resistivity of polyurushiol/silver (PU/Ag) composite films reached the value of 0.26 Ω cm, when the content of Ag particles in composite films was 23.8 wt%, and the irradiation time 90 s. Additionally, Ag particles were well dispersed in the composite films. And the films had good thermo-stability.

Research highlights▶ Polyurushiol/silver conductive coatings are prepared under UV irradiation. AgNO3 loading and irradiation time play a key role in the formation of composites. ▶ The best AgNO3 loading and irradiation time are PU/Ag-D and 90 s. ▶ The films have excellent conductivity and good thermo-stability.
