PEDOT:PSS/PVA涂层导电织物的制备及其性能
Preparation and properties of PEDOT:PSS/PVA-coated conductive fabrics
摘要
Abstract
To expand the application of polyester fabrics in the field of electronic textiles,it is necessary to endow them with conductivity.Therefore,in this study,the conductive coating was prepared by using PEDOT:PSS(Poly(3,4-ethylenedioxythiophene):polystyrene sulfonate),EG(ethylene glycol)and PVA(polyvinyl alcohol),and the conductive coating was evenly coated on the polyester fabric by"coating-drying"method to prepare the PEDOT:PSS/PVA-coated conductive fabric.Firstly,the optimal range of coating times was determined to be 8,10,12 times by single factor experiment to ensure the uniformity of PEDOT:PSS/PVA-coated conductive fabrics.On this basis,the orthogonal experiment of three factors and three levels was designed,and the optimal combination parameters of EG addition amount,PVA solution addition amount and coating times were obtained.The PEDOT:PSS/PVA-coated conductive fabric prepared under the optimal combination parameters showed good electrical conductivity with a resistance of 4.48 Ω and a volume resistivity of 0.09 Ω·cm.In terms of laundering durability,mechanical properties and biocompatibility,the test results show that the coated conductive fabric has certain laundering durability,and the resistivity after 10 washes is 1.35 Ω·cm,which is because PVA makes the conduc-tive coating not easy to fall off.The fast and slow elastic recovery retention rates of the coated conductive fabric are 59.77％-70.34％and 63.26％-74.43％,respectively.The average breaking strength and elongation at break increase by 59.73 N(6.15％)and 40.4 N(5.78％),respectively,and the improvement of tensile properties is attributed to the synergistic tensile properties of PVA.Additionally,after four hours of contact with the skin,the coated conductive fabric does not cause redness,swelling,or allergic reactions,demonstrating good biocompatibility. In summary,PEDOT:PSS/PVA-coated conductive fabrics not only perform well in terms of electrical conductivity,but also show excellent properties in terms of laundering durability,mechanical properties and biocompatibility,and have broad application prospects in the field of electronic textiles.关键词
