英文摘要	On the surface of self-made PEDOT-PSS/PVA conductive textiles, compact and uniform PEDOT-PSS conductive coating is formed by in situ polymerization, and the resulted composite conductive textile is called in situ PEDOT-PSS/PVA. The synthesis conditions of the in situ polymerization are optimized. The morphology, structure and properties of the in situ PEDOT-PSS/PVA are measured. It is shown that the optimum molar ration of the reactant is [PSS]:[FeCl3]:[EDOT] = 2.1: 1.4: 1 with a reaction time of 10 h. The resulted in situ PEDOT-PSS/PVA has excellent conductive property with a low surface resistance of 2 Omega/rectangle and electron conductivity of 360 S/cm under the optimized synthesis condition, which may be resulted from the synergistic action between PEDOT-PSS inside the fiber and the surface coating, forming the connected and effective conductive path to facilitate the electron transport. FTIR analysis indicates that there exists strong bonding force between base textile and PEDOT-PSS coating. Besides, the in situ PEDOT-PSS/PVA has strong near infrared shielding capability. The XPS measurements show that the sulfur content of the in situ PEDOT-PSS/PVA is much higher than that of the PEDOT-PSS/PVA, implying a higher PEDOT-PSS conductive component, which is also responsible for its low surface resistance. Moreover, the electromagnetic shielding measurements demonstrate that the electromagnetic shielding effectiveness of the in situ PEDOT-PSS/PVA can reach to 12 dB with a shielding efficiency of 75% compared with the 0 dB of PEDOT-PSS/PVA. In the range of 4 similar to 18 GHz, the most reflectivity of electromagnetic wave is between -5 and -10 dB, which can absorb 75% similar to 90% electromagnetic wave. Furthermore, the in situ PEDOT-PSS/PVA composite conductive textile presents a higher stability, good fastness to washing and acid resistance. The results indicate that the in situ polymerization is an effective method to improve the conductive property of PEDOT-PSS/PVA conductive textile, and the resulted in situ PEDOT-PSS/PVA composite conductive textile has an important application prospect as a novel kind of military electromagnetic wave absorption material.
