包芯纱基摩擦电织物的制备及性能
Preparation and properties of triboelectric fabrics based on core-spun yarn
摘要
Abstract
In order to achieve the effective combination of the triboelectric layer and the electrode in textile based triboelec-tric nanogenerators(TENG),the core-spun yarns with polyimide(PI)or polyphenylene sulfide(PPS)as tribo-electric material and stainless-steel yarn as electrode were prepared using conjugate-electrospinning or continu-ous hollow spindle fancy twisting technology.Then,the triboelectric fabrics with full weft were prepared by weaving process in which the core-spun yarns served as the weft yarns.The effect of friction layer microstructure on the performance of the TENG,the working adaptability of the TENG in high-temperature environment,and the practical application performance of the fabric based TENG were investigated.The results show that when PPS staple fiber core-spun yarn based fabric and PI nanofiber core-spun yarn based fabric were respectively the positive and negative triboelectric layers of the TENG,because of the effective matching between micro-and nano-fibers to increase the effective working area,the fabric based TENG showed the optimum triboelectric properties,and it could maintain stable operation in a high-temperature environment below 200 ℃.When the load resistance was 20 MΩ,the TENG has a power density of 0.67 W/m2 and could light up 18 COBs or 140 LEDs,or charge capacitors to further power calculators,demonstrating its potential applications in the field of powering wearable microelectronics.关键词
