β-Phase-Preferential Blow-spun Fabrics for Wearable Triboelectric Nanogenerators and Textile Interactive Interface

다국어 초록 (Multilingual Abstract)

Wearable textile electronics have been extensively developed with versatile functionality and self-powered autonomy. The nonwoven fabric fabricated by solution blow spinning (SBS) was successfully applied as the triboelectric layer in TENGs. The uniaxial elongation of the polymer chains along the fiber axis during the SBS process promoted the formation of polar β-phase crystals in the solution-blow-spun nanofibers, which led to a negative shift in the surface potential and enhancement of the TENG performances. The constructed fabric TENG delivered excellent output performances such as a high open-circuit voltage of 260 V, short-circuit current of 27μA, and high output power of 7mW. The proposed β-phase-preferential blow-spun fabric TENGs are highly promising for application to next-generation intelligent textronics and self-powered human robot interaction interfaces.
