▎ 摘  要

Massive production of graphene is synthesized by a low-cost electro-chemically exfoliated approach and then incorporated with gamma-alumina for developing a novel carbon composite ink, graphene/gamma-alumina ink. It is coated onto the glass by spraying with an adiabatic closed system as the thermal and optical barriers for the energy efficient glass of the business buildings. The coating thickness of graphene/gamma-alumina layer is around 2-3 pm. The temperature in an adiabatic closed system is measured with a heat source by lamp radiation. The temperature difference between inside and outside of the adiabatic closed system can achieve around 20 degrees C with the coating of 0.3 wt% of electro-chemically exfoliated graphene incorporated with 1 wt% of gamma-alumina in N-Methyl-2-Pyrrolidone after thermal radiation test for 15 h. The transmittance is adjustable from 5.57%-81% at 550 nm wavelength, depending on the composition and content of graphene and gamma-alumina. The coating of the carbon composite ink, electro-chemically exfoliated graphene with gamma-alumina are also good absorbents for UV absorbance.
