PPy/rGO涤棉复合织物的制备及其电磁性能研究
Preparation of PPy/rGOPolyester/Cotton Composite Fabric and Its Electromagnetic Performance Research
摘要
Abstract
At present,the problem of electromagnetic radiation pollution has attracted great attention,and there is an urgent need to prepare electromagnetic wave-absorbing materials with excellent performance.For indi-vidual protection,the study of multi-functional composite fabrics integrating wave absorption,pressure sensing,electric heating and energy storage is of great significance for flexible wearability and clothing intelligence.In this paper,polyester/cotton fabrics were taken as flexible substrates and PPy and rGO as functional particles,PPy/rGO composite flexible fabrics were prepared by chemical reduction and in-situ polymerization methods.The effects of Py concentration on its wave-absorbing,dielectric,conductive,electrochemical,piezoresistive and e-lectrothermal performance were mainly investigated.The results showed that when the concentration of Py was 0.4 mol/L,the composite fabric had the minimum reflection loss(RLmin)of-6.62 dB at the frequency of 15.60 GHz,the surface resistance value was 127.8 Ω,and the maximum temperature of electrothermal heating was 46.36℃,the composite fabric had the best wave-absorbing,conductive and electrothermal performance.When the Py concentration was 0.2 mol/L and the sensitivity was 6.09 kPa-1,the piezoresistive sensing performance was best.When the Py concentration was 0.6 mol/L,the mass-specific capacitance was 45.91 F/g,the electrochem-ical performance was best.关键词
