Multifunctional wearable heaters have attracted much attention owing to their efficient application in personal thermal management. Inspired by the polar bear's thermal management, a laminated fabric with enhanced photothermal conversion, mid-infrared reflection, thermal insulation, and electrical heating performance was developed in this work, which was made of CNT/cellulose aerogel layers, cotton fabrics, and copper nanowire (CuNW)-based conductive network (CNN) layers. The CNN layer made up of highly conductive CuNWs not only exhibits better conductivity to realize the Joule heating effect but also possesses a human mid-infrared reflection property. Moreover, the other side of the cotton fabric was laminated with CNT/cellulose aerogel, which enables the fabric to have a good photothermal conversion ability and thermal insulation performance. The temperature of the laminated fabric could reach to 70 °C within 80 s under 1.8 V; it requires more than 500 s to return to room temperature (28.7 °C). When the light intensity was adjusted to 1000 W/m, the temperature of the laminated fabric was about 74.0 °C after lighting for 280 s. Our work provides a new approach to improving the performance and energy-saving of personal thermal management fabrics.

The transfer of large-area, continuous, chemical vapor deposition (CVD)-grown graphene without introducing defects remains a challenge for fabricating graphene-based electronics. Polymer thin films are commonly used as supports for transferring graphene, but they typically require thermal annealing before transfer. However, little work has been done to thoroughly investigate how thermal annealing affects the polymer/graphene thin film when directly annealed on the growth substrate.

Ammonia borane (NHBH, AB) is considered a promising chemical hydrogen storage material. The development of efficient, stable, and economical catalysts for AB hydrolysis is essential for realizing the hydrogen energy economy. In this study, a series of p-p heterojunction catalysts, labeled M (P/S/Cl)-CuCoO, were fabricated using the high-temperature vapor phase method to achieve anionic interface gradient doping.

Laminating a free-standing carbon electrode film onto perovskite film is a promising method for fabricating HTM (hole transport material)-free carbon electrode perovskite solar cells (c-PSCs), offering more flexibility by decoupling the processes of carbon electrode and perovskite layer formation. However, the power conversion efficiency (PCE) of laminated HTM-free c-PSCs (<16.5%) remains lower compared to c-PSCs with printed carbon pastes (>20%), primarily due to poor interfacial contact between the perovskite and carbon layers.
