Property study of nano antimony tin oxide/polypyrrole composite conductive coated cotton fabric
In order to improve the electrical conductivity of flexible electronic textiles and explore the influence of layers for multiple components electrical coated layer assembly on fabric property,the nano antimony tin oxide/polypyrrole(ATO@WPU/PPy)bio-component conductive coating was constructed on cotton fabric substrate by dipping-assisted layer-by-layer assembly technique.The microstructure,quality,thickness,permeability,electrical conductivity,flame retardancy and thermal stability of different coated cotton fabrics were tested and compared with nano antimony tin oxide/poly dimethyl diallyl ammonium chloride(ATO@WPU/PDDA)single component conductive coated fabric.The results showed that with the increase of ATO@WPU/PPy assembly layer,the surface coating load of cotton fabrics was increased,and the surface resistance of the bio-component composite conductive coated cotton fabric was decreased,the lowest was 1.4 kΩ/sq,while the surface resistance of the ATO@WPU/PDDA single-component conductive coated fabric with the same assembly layers was 37.3 kΩ/sq.It indicated that the electrical conductivity of the bio-component composite coated cotton fabric was significantly improved.The flame retardancy and thermal stability of ATO@WPU/PPy composite coated cotton fabric were also gradually improved.It is considered that the performance of the prepared cotton fabric with bio-component conductive coating is better than that of the fabric with single-component conductive coating.It has advantages in the development of flexible electronic textile devices.
