Preparation and Thermoelectric Properties of Flexible PU/CNT/PEDOT:PSS Composite Fibrous Membrane

摘要：

　　Thermoelectric(TE)composites based on conductive polymers/carbon nanotubes,such as poly(3,4-ethylened-ioxythiophene):poly(styrene sulfonate)(PEDOT:PSS)/CNT composites,have become the research hotspot of organic TE materials due to their outstanding composite performance and high flexibility.However,the PEDOT:PSS/CNT composites reported currently lack tensile properties.Here,we report a PU/CNT/PEDOT:PSS composite fibrous membrane with good flexibility and stretchability.The flexible and stretchable PU/CNT/PEDOT:PSS composite fibrous membrane was prepared by electrospinning and electrostatic spraying technology.The electrospun PU nanofibers were used as the elastic matrix of the composite fibrous membrane,and CNT/PEDOT:PSS was sprayed onto the surface of the PU nanofibers by electrostatic spra-ying technology.We investigated the effect of PU/CNT with different mass ratios on the thermoelectric properties of the PU/CNT/PEDOT:PSS composite fibrous membranes.The optimum mass ratio of PU/CNT was 1:4,and the Seebeck coeffi-cient of the composite fibrous membrane was 17.43 μV/K.In addition,we demonstrated the flexibility of the composite fi-brous membrane and found that the PU/CNT/PEDOT:PSS fibrous membrane has good flexibility and stretchability.The PU/CNT/PEDOT:PSS fibrous membrane reported in this paper provides a new idea for the preparation of high-performance stretchable thermoelectric materials.It's expected to be applied in the field of wearable devices in the future.
