Abstract
Transparent flexible heaters attract great attention due to their potential applications in smart windows, wearable electronics, hand warmers, etc. Here, we present a highly flexible cellulose/zinc oxide/indium tin oxide (CZI) film heater, which was prepared by spinning coating of zinc oxide (ZnO) solution on cellulose film followed by magnetron sputtering of indium tin oxide (ITO). The CZI film exhibits a high visible light transmittance (80.3%), low resistance (7.3 Ω·sq−1), and good thermostability. As connected to the circuit, the CZI film showed an excellent Joule heating performance even after multiple repeated bending tests. The temperature of the CZI film could increase from room temperature to 89 ℃ within 2 min under the working voltage of 6 V. Prompted by these versatile properties, and we demoed the application scenarios of this CZI film heater in thermochromism, deicing, and defogging to enlighten for the application of this film material in sensors or smart windows.
期刊介绍:
Cellulose is an international journal devoted to the dissemination of research and scientific and technological progress in the field of cellulose and related naturally occurring polymers. The journal is concerned with the pure and applied science of cellulose and related materials, and also with the development of relevant new technologies. This includes the chemistry, biochemistry, physics and materials science of cellulose and its sources, including wood and other biomass resources, and their derivatives. Coverage extends to the conversion of these polymers and resources into manufactured goods, such as pulp, paper, textiles, and manufactured as well natural fibers, and to the chemistry of materials used in their processing. Cellulose publishes review articles, research papers, and technical notes.
