摘　　要：Herein,electrically conductive natural and synthetic yarns through electrophoretic deposition(EPD)technique were fabricated.A parametric study on the conductivity enhancement of the yarns is carried out by Taguchi method.Using this method,the desirable conditions are determined by studying the effects of important parameters on the electrical conductivity of the yarns in the EPD coating process.Based on the L18 design of experiments table,the preferred combination of factors to obtain the highest electrical conductivity of the yarns is found by Taguchi analysis.In addition,the Pareto ANOVA analysis is conducted to identify the major contributing factors on the electrical conductivity of the yarns.Characterisation techniques,such as scanning electron microscopy(SEM),Fourier transformed infrared spectroscopy(FTIR)in attenuated total reflectance(ATR)mode,and thermogravimetric analysis(TGA)are utilised for better understanding the microstructure and physical properties.When powered by only 3 V,the maximum temperature of a Joule heated conductive sample based on natural fibre yarns reached 102°C in less than 25 s.
