- Abstract
- The electrical conductivity and the thermal performance of the films made of reduced graphene oxide (rGO) spray-coated on polycarbonate substrate were investigated. The electrical conductivity and the transmittance of 10 times spray coated film made from the solution with 0.08 wt% of rGO, 0.16 wt% of surfactant were 30 k Omega/sq and 64%, respectively. The steady-state temperature of the films increased from 25 degrees C for 40 k Omega/sq to 100 degrees C for 490 Omega/sq at an applied voltage of 110 V. The heat transfer coefficient of the rGO coated film, alpha, was obtained as 139 W/m(2)K using the model equation based on the thermal balance, which includes Joule heating convectional, and radiative heat transfers. The transmittance of the films decreased continuously from 73% with the increase of surface resistivity.
