Abstract

The invention discloses a heater based on a transparent silver nanowire conducting thin film and a preparation method of the heater. The heater is simple in structure, uniform in heating and resistant to corrosion. The heater comprises a transparent substrate, the transparent conducting thin film, a conducting electrode and a protective layer. The heater is applied to defogging glass, a thermochromic substrate, a sensor substrate and the like. The preparation method of the heater comprises the steps of hydrophilization processing of the substrate, preparation of the transparent conducting thin film, preparation of the conducting electrode and preparation of the protective layer. According to the heater, silver nanowires synthesized through a low-temperature liquid phase method are used as raw materials, the transparent substrate is coated with the transparent conducting thin film through a non-vacuum non-high-temperature filming technology, the heating uniformity of the thin film is improved through technically mature and commercial conducting polymers, and the thin-layer protective film is obtained by means of liquid phase coating of cheap organic polymers. The heater is simple in structure, the raw materials are cheap, the requirement for preparation technological conditions is low, and large-scale production is facilitated.

Description

technical field [0001] The invention relates to a transparent heater and its application, in particular to a heating substrate that can be used as a defogging glass, a liquid crystal display, a visual reactor, a refrigerator and a freezer window, a thermochromic instrument, a high-sensitivity sensor, etc. A silver nanowire transparent conductive film heater and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of science and technology, people's pursuit of intelligence has become more and more common. For example, driving cars can quickly defog glass, refrigerators and freezer windows can automatically defog, ornamental fish tanks can automatically heat water, windows Glass can automatically change color and so on. Achieving these intelligent requirements requires a transparent heater, that is, an electric heater based on a transparent conductive film. Traditional transparent heaters generally use metal oxide transparen...
