本文提出一种采用氧化还原一步法制备聚苯胺/银复合导电织物的新方法,并通过扫描电镜、红外光谱、X射线光电子能谱分析及热重分析仪对制备的导电织物的表面形貌、化学组成及热稳定性进行了表征;研究了该织物的导电性能、力学性能,以及水洗次数对其导电性能的影响。结果表明,采用氧化还原一步法能够较好的在涤纶织物表面形成聚苯胺/银的复合镀层;经镀层处理后的织物热稳定性及导电性能均有所提高,力学性能变化较小,且经50次水洗后,其导电性能优于聚苯胺织物。本研究为开发具有高导电性、低成本的导电织物提供了新的方法和思路。 相似文献

Conductive yarns are used for integration of sensors and other electronic devices with textile fabrics through weaving, knitting, braiding or embroidery processes. In the lifetime of the textile also several washing cycles might occur. These processes involve rubbing which may lead to displacement of conductive fibres, causing short circuiting between the neighbouring conductive fibres. Also the textile products made with conductive fibres may have to work in the presence of water, where the exposed conductive fibres can get short circuited. In this work, an attempt has been made to protect silver-coated polyamide yarns with polypropylene (PP). This is done through wrapping the PP staple fibres around the silver-coated polyamide yarns through friction spinning and melting the PP sheath fibres in an oven. The influence of twist in the conductive yarns, amount of PP coating and the oven temperature during coating process on the tenacity, electrical insulation in the presence of water and flexibility properties of the coated yarns are studied. The PP coated yarns with plied conductive yarn in the core provide better flexibility but need higher amount of coating to provide complete electrical insulation in the presence of water as compared to those yarns with single conductive yarn in the core. 相似文献

Polypyrrole-coated cotton conductive fabrics were prepared by in situ polymerization. The influences of pyrrole dosage, mole ratio of pyrrole to iron (III) chloride, reaction temperature and reaction time on the conductivity of the polypyrrole-coated cotton conductive fabrics were analyzed. The best method for preparing the polypyrrole-coated cotton conductive fabrics was determined. The structures of the conductive cotton fabrics were characterized with Fourier transform infrared spectroscopy and scanning electron microscopy. The results showed that when mo1e ratio of pyrrole to iron (III) chloride was 2:1, reaction at room temperature for 1 h with a bath ratio of 1:40, the conductivity of the prepared fabric was the best with a surface resistance of 0.15 kΩ/cm. The chemical structure and the surface morphological structures of the conductive cotton fabrics were different from that of the untreated cotton fabrics. By in situ polymerization, the fiber surfaces appeared homogeneously coated with a film of polypyrrole. Importantly, the process of pyrrole polymerization is very simple. This study offers a new simple way for preparing the polypyrrole-coated cotton conductive fabrics effectively. 相似文献
