| Abstract |
High-performing transparent heater was achieved by using silver nanowires (AgNWs). The AgNWs were networked through spin coating method. In order to protect AgNWs from deformation according to heating operation, a functional metal oxide (ZnO) was coated over the AgNWs. To preserve the optical transparency, FTO-coated glass was adopted as the substrate. The transparent heater has a structure of ZnO/AgNWs/FTO/glass has more than 70% transmittance at the wavelength of 550 nm. The heating temperature of the transparent heater was reached over 300℃. The functional ZnO coated AgNWs transparent heater was stable for the thermal-cyclic operation, meanwhile, the bare AgNWs heater showed unstable and fluctuation in heating temperature. The stable operation of the transparent heater was demonstrated for the excellent water evaporation function, demisting and deicing performances. This high transparent heater has high potential to be applied for windows of transportation vehicles and buildings. |
