Abstract
Official abstract text for this publication.
Provided is a transparent film heater including: a transparent substrate 100 ; and a heat-emitting layer 200 that includes conductive nanowires 10 forming a network, and a coating material 20 applied to the nanowires 10 and functioning to bind the nanowires 10 with each other, is disposed on the transparent substrate 100 , and emits heat upon the application of a voltage.
First claim
Opening claim text (preview).
What is claimed is: 1 . A transparent film heater comprising: a transparent substrate; and a heat-emitting layer that comprises conductive nanowires forming a network, and a coating material applied to the nanowires and functioning to bind the nanowires with each other, is disposed on the transparent substrate, and emits heat upon the application of a voltage. 2 . The transparent film heater according to claim 1 , wherein the transparent substrate has flexibility. 3 . The transparent film heater according to claim 1 , wherein the transparent substrate is a substrate having a light transmission of at least 80%. 4 . The transparent film heater according to claim 1 , wherein the nanowires are silver (Ag) nanowires. 5 . The transparent film heater according to claim 1 , wherein the coating material is indium tin oxide (ITO) or aluminum zinc oxide (AZO). 6 . The transparent film heater according to claim 1 , which further comprises an electrode terminal layer disposed at either side edge of the heat-emitting layer. 7 . The transparent film heater according to claim 1 , wherein the transparent substrate is disposed on a display panel, periscope, defroster or goggle. 8 . A method for manufacturing a transparent film heater, comprising the steps of: (A) mixing conductive nanowires forming a network with a solvent to provide a nanowire solution; (B) applying the nanowire solution to a transparent substrate; and (C) applying a coating material to the nanowires applied to the transparent substrate to form a heat-emitting layer that emits heat upon the application of a voltage. 9 . The method for manufacturing a transparent film heater according to claim 8 , wherein the transparent substrate has flexibility. 10 . The method for manufacturing a transparent film heater according to claim 8 , wherein the transparent substrate is a substrate having a light transmission of at least 80%. 11 . The method for manufacturing a transparent film heater according to claim 8 , wherein the nanowires are silver (Ag) nanowires. 12 . The method for manufacturing a transparent film heater according to claim 8 , wherein the coating material is indium tin oxide (ITO) or aluminum zinc oxide (AZO). 13 . The method for manufacturing a transparent film heater according to claim 8 , which further comprises a step of additionally applying the nanowire solution at least once, after the step of applying the nanowires. 14 . The method for manufacturing a transparent film heater according to claim 13 , which further comprises, after the step of additionally applying the nanowire solution, a step of heat treating the additionally applied nanowire solution. 15 . The method for manufacturing a transparent film heater according to claim 8 , which further comprises a step of disposing an electrode terminal layer for applying the voltage at either side of the heat-emitting layer, after the step of forming the heat-emitting layer.
