“…[29] Jia et al prepared chitosan/graphene oxide/gelatin (CS/GA/GO) mixed fiber by wet spinning process, and obtained better mechanical properties and efficient photothermal conversion ability. [30] In addition, the thermal conductivity of GO (3.19 W m −1 K −1 ) is much lower than that of graphene (5000 W m −1 K −1 ), [31,32] avoiding the reduction of the thermal insulation of the prepared GO-doped aerogel fibers. Besides, polydopamine (PDA) is a polymeric nearinfrared absorbing material with broadband absorption in the UV to visible range and light absorption extending all the way to the near-infrared region with high photothermal conversion efficiency and good biosafety, and strong adhesion on almost any surface.…”

The porous nature and gel network of aerogel fibers make them ideal options for personal thermal management because they can significantly cut down on energy waste. However, aerogel fibers generally suffer from poor mechanical properties and single function. Herein, we investigated porous continuous bacterial cellulose/graphene oxide@polydopamine core‐shell aerogel fibers (BC/GO@PDA) with high strength, excellent photothermal properties and thermal insulation by wet spinning and freeze‐drying. The bacterial cellulose/graphene oxide@polydopamine aerogel fiber prepared by wet spinning method has a porous structure, which can prevent heat convection, reduce heat conduction and suppress heat radiation, making the aerogel fiber have excellent thermal insulation properties. More crucially, graphene oxide may considerably enhance infrared radiation's capacity for heating, while polydopamine can enhance ultraviolet light absorption and boost photothermal conversion capability.This article is protected by copyright.
