摘要
Abstract
To enhance the capacitive performance of flexible fabrics,we proposed a novel approach that leverages the three-dimensional random distribution of metal fibers within stainless steel/polyester(SS/PET)blended yarns.By arranging electrodes at fixed intervals along the yarns and applying a voltage across these electrodes,a three-dimensional interdigitated electrode structure was formed among the stainless steel fibers(SS)that are in direct contact with the electrodes.Through the interconnection of electrodes with the same polarity,multiple interdigitated electrode units were connected in parallel,thereby significantly enhancing the overall capacitance of the fab-ric.The influence of key structural parameters(e.g.,metal fiber content,weft density,electrode spacing,and fabric dimensions)on the electrical behavior was systematically investigated.Experi-mental results demonstrate that increasing the weft density and SS fiber content can substantially elevate the fabric's capacitance.Specifically,when the weft density reaches 156 ends/10 cm and the SS content is 5％,the capacitance value is 39 times greater than that of a fabric with only 1％SS content.Moreover,the maximum capacitance is achieved when the electrode spacing closely matches the length of the metal fibers.Increasing the fabric size also leads to a notable enhance-ment in capacitance performance,with a 230％increase in length resulting in approximately a 303％increase in capacitance.This research offers a new design strategy for capacitive superposi-tion-type flexible fabrics based on interdigitated electrode structures,showing promising potential for applications in electromagnetic shielding and flexible energy storage systems.关键词
