Anti‐Swelling Textile Power Generator with 1D Nanoscale Channel Alignment in Nanofiber/Graphene Hybrid Yarns

Advanced Functional Materials, EarlyView.
A nanofiber/graphene hybrid yarn with 1D oriented nanoscale channel is constructed via bath electrospinning followed by a functionalization process, yielding exceptional anti‐swelling and weaving abilities. When configured into a waterproof fabric through series‐parallel connection of 62‐cm yarns, an output power of 31.96 µW is achieved, which could ...
