A cupronickel-based micromesh film for use as a high-performance and low-voltage transparent heater

Abstract

The fabrication of uniformly interconnected cupronickel (CuNi) micromesh films on glass and polymer substrates with seamless junctions has been achieved using a simple transfer printing method. When used as a transparent heater, these CuNi micromesh films exhibited an effective and rapid heating performance at low input voltages (below DC 9 V) that can be attributed to the creation of a high quality network over the whole surface area that offers a relatively high transmittance, strong adhesion to its substrate and good mechanical flexibility. A high thermal stability and reliability was also observed relative to a pure Cu micromesh film. Transparent heaters based on CuNi micromesh are therefore considered suitable for providing anti-fogging or de-icing in optics and optoelectronic devices, as well as for wearable heating systems.

Droplet evaporation characteristics on transparent heaters with different wettabilities

“…Recently, transparent heaters have attracted considerable attention as defogging/deicing (or anti-fogging/anti-icing) devices or heating sources for automobiles, sensors, bio-chips, and greenhouses. [9][10][11][12][13] Studies of transparent heaters have been focused on their manufacturing processes and heat-generation performances, whereas droplet evaporation on transparent heaters has never been investigated. However, such research must be conducted to develop more effective transparentheater-based defogging/deicing devices.…”

Observation of convection phenomenon by high-performance transparent heater based on Pt-decorated Ni micromesh

“…The Ni micromesh film was prepared in a two-terminal side-contact configuration to assess the performance of the film as a transparent heater. 20 As shown in Fig. 2(a), each Pt-decorated Ni micromesh film creates an Ohmic contact which decreases in electrical resistance as the Pt decoration is increased on the surface of the Ni micromesh film.…”

“…We recently reported on the fabrication of uniform metal mesh structures on various substrates of glass and flexible plastic films in our previous studies. 11,20 As shown in Fig. 1(a), a large-scale (100 mm × 100 mm) transparent Ni micromesh structure is successfully fabricated on the glass substrate, which has a width of 1.8 µm and a pitch of 100 µm.…”

Screen‐Printed, Low‐Cost, and Patterned Flexible Heater Based on Ag Fractal Dendrites for Human Wearable Application

“…Currently, various printed electronic techniques have been applied to manufacture flexible resistance heaters, such as bar coating . spin coating, spray printing, and transfer printing . However, these techniques are either expensive or unsuitable for large‐scale fabrication, resulting in high costs finally.…”
