透明加热器广泛应用于窗户除雾/除雾、显示器、气体传感和医疗设备等技术。除了机械坚固性以及电气和光学可靠性外，出色的化学稳定性对于透明加热器的应用也至关重要。在这方面，我们首先提出了一个高度灵活的和大面积的CuS透明加热器制造的胶体裂纹图案的方法与优化的薄层电阻（Rs）低至21.5 Ω sq−1在一个80%的透射率。CuS透明加热器在弯曲测试中表现出出色的机械坚固性以及对酸和碱环境的高化学稳定性。在作为透明加热器的应用中，CuS加热器表现出197 °C W−1 cm 2的高热阻，具有快速开关时间（<30 s），需要低输入电压（<4.5 V）才能在大面积上实现110 °C的均匀温度。可穿戴CuS加热器贴在皮肤上，可以通过手机中的蓝牙设备无线实时控制温度。基于无线控制系统，我们演示了CuS加热器在太阳能电池板除雪中的应用。这些CuS网络TCE具有高柔性、透明性、导电性和化学稳定性，可广泛应用于可穿戴电子产品。
Transparent heaters are widely used in technologies such as window defrosting/defogging, displays, gas sensing, and medical equipment. Apart from mechanical robustness and electrical and optical reliabilities, outstanding chemical stability is also critical to the application of transparent heaters. In this regard, we first present a highly flexible and large-area CuS transparent heater fabricated by a colloidal crackle pattern method with an optimized sheet resistance (Rs) as low as 21.5 Ω sq−1 at a ∼80% transmittance. The CuS transparent heater exhibits remarkable mechanical robustness during bending tests as well as high chemical stability against acid and alkali environments. In the application as a transparent heater, the CuS heater demonstrates a high thermal resistance of 197 °C W−1 cm2 with a fast switching time (<30 s), requiring low input voltages (<4.5 V) to achieve uniform temperatures of ∼110 °C across large areas. The temperature of the wearable CuS heater, which is stuck on the skin, can be real-time controlled through a Bluetooth device in a cell phone wirelessly. Based on the wireless control system, we demonstrated an application of the CuS heater in snow removal for solar panels. These CuS network TCEs with high flexibility, transparency, conductivity, and chemical stability could be widely used in wearable electronic products.
