Abstract

Wearable heaters promise to maintain personal thermal comfort during sudden changes in climate conditions. However, creating a dual-energy supply and flexible wearable heater with stable and continuous heating that functions effectively remains a significant challenge. We develop a multimode cellulose fabric heater driven by solar and electricity via in situ polymerization and reduction reaction for all-day wearable thermal comfort. The cellulose fabric heater features a strong light absorption of 96% in the solar spectrum, owing to the synergistic effects of graphene oxide (GO) on polyaniline (PANI). The cellulose fabric heater enables superior photothermal performance on a sunny day, and a high surface temperature of 75.2 °C is obtained at the simulated solar light of 600 W m^–2 for 300 s. Due to the high conductivity and stable Joule heating effect of PANI and reduced graphene oxide (rGO), the cellulose fabric heater exhibits exceptional electrothermal performance at night. It reaches an equilibrium temperature of 55.1 °C at 10.0 V for 120 s. The compromised photothermal and electrothermal properties of this heater are achieved on cloudy days, confirming its substantial advantages in all-day wearable heating.

太极启发太阳能/电驱动多模式纤维素织物加热器全天可穿戴热舒适

可穿戴加热器承诺在气候条件突然变化时保持个人热舒适。然而，创造一种双能量供应和灵活的可穿戴加热器，具有稳定和持续的加热功能，仍然是一个重大挑战。我们通过原位聚合和还原反应，开发了一种太阳能和电力驱动的多模式纤维素织物加热器，用于全天候可穿戴的热舒适。由于氧化石墨烯（GO）对聚苯胺（PANI）的协同作用，纤维素织物加热器在太阳光谱中具有96%的强光吸收率。纤维素织物加热器在阳光明媚的日子里具有优越的光热性能，在600 W m-2的模拟太阳光下，表面温度高达75.2°C，持续300 s。由于聚苯胺和还原氧化石墨烯（rGO）的高导电性和稳定的焦耳热效应，纤维素织物加热器在夜间表现出优异的电热性能。在10.0 V下加热120 s，达到55.1℃的平衡温度。这种加热器的光热和电热性能在阴天达到了折衷，证实了它在全天可穿戴加热方面的实质性优势。
