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.
