纤维素纳米晶提高柔性导电聚丙烯腈@碳纳米管纳米纤维膜的拉伸性能
Improving Tensile Properties of Flexible Conductive Polyacrylonitrile@Carbon Nanotube Nanofiber Membrane by Cellulose Nanocrystal
摘要
Abstract
The flexible conductive nanofiber membrane is widely used in the field of wearable electronics.High tensile properties of electrospun nanofiber membranes are essential for their successful commercial application.With cellulose nanocrystal(CNC)as the reinforcement,the flexible conductive polyacrylonitrile(PAN)/CNC@carbon nanotube(CNT)nanofiber membrane is electrospun from the PAN solution containing suspended CNC and impregnated with the CNT solution.The structure and properties of nanofiber membranes are studied.The results show that with the increase of the PAN mass fraction,the viscosity of the electrospinning solution increases,leading to an increase in the nanofiber diameter.When the mass fraction of PAN is 12%,PAN/CNC nanofiber membranes at different CNC mass fractions are successfully prepared.The structure and properties of PAN/CNC nanofiber membranes are affected by the addition of CNC.As the CNC mass fraction increases,the nanofibers become thicker,the nanofiber diameter distribution widens,and the tensile strength first increases and then decreases.When the mass ratio of PAN to CNC is 4∶1,the tensile strength of the PAN/CNC nanofiber membrane is the highest,and it is higher than that of the PAN nanofiber membrane.After impregnating the PAN/CNC nanofiber membrane with CNTs,the tensile strength of the nanofiber membrane increases to 3.12 MPa and the surface resistivity is 64 Ω/cm2.The flexible conductive nanofiber membranes would be used in energy storage and sensing fields,and the study might provide a strong base for their future development.关键词
