Abstract
A planar heating structure is disclosed. The planar heating structure includes a glass substrate layer, a nanometallic transparent conductive layer, and a first passivation layer. The nanometallic transparent conductive layer is disposed on the glass substrate layer and receives a voltage to generate heat energy. The first passivation layer is disposed on the nanometallic transparent conductive layer and completely covers the nanometallic transparent conductive layer.

A planar heating structure, comprising:
- a glass substrate layer;
- a nanometallic transparent conductive layer having a plurality of metal nanowires disposed on the glass substrate layer and receiving electrical energy to convert the electrical energy into heat energy, wherein more than 92% of the metal nanowires have a length greater than 5 μm;
- a first passivation layer disposed on the nanometallic transparent conductive layer and completely covering the nanometallic transparent conductive layer, wherein a thermal conductivity of the first passivation layer is lower than that of the glass substrate layer so that most of the heat energy converted from the electrical energy is discharged from the glass substrate layer in a conductive manner or a radiating manner;
- and
- two electrodes located on two opposite sides of the planar heating structure having a shortest relative distance, a voltage being applied between the two electrodes,
- wherein, when the voltage is substantially 40 volts and when per square centimeter of a surface the planar heating structure consumes a power of 0.07 W, the planar heating structure has a temperature rise of 12° C.±1° C. within 2 minutes.
A planar heating structure for bonding to glass, comprising:
- a flexible substrate layer;
- a nanometallic transparent conductive layer having a plurality of metal nanowires disposed on the flexible substrate layer and receiving electrical energy to convert the electrical energy into heat energy, wherein more than 92% of the metal nanowires have a length greater than 5 μm;
- an adhesive layer disposed on the nanometallic transparent conductive layer;
- a release film formed on a surface of the adhesive layer away from the nanometallic transparent conductive layer;
- a first passivation layer disposed on the nanometallic transparent conductive layer and completely covering the nanometallic transparent conductive layer, wherein a thermal conductivity of the first passivation layer is lower than that of the flexible substrate layer so that most of the heat energy converted from the electrical energy is discharged from the flexible substrate layer in a conductive manner or a radiating manner;
- and
- two electrodes located on two opposite sides of the planar heating structure having a shortest relative distance, a voltage being applied between the two electrodes,
- wherein, when the voltage is substantially 40 volts and when per square centimeter of a surface the planar heating structure consumes a power of 0.07 W, the planar heating structure has a temperature rise of 12° C.±1° C. within 2 minutes.
