Abstract

In this study, the effect of the addition of conductive materials on the solution properties, electrospinning behavior, and electrospun web structure of polyvinylidene fluoride (PVDF) was investigated. A PVDF/single-walled carbon nanotube (SWCNT) composite was prepared by adding various amounts of SWCNT to a PVDF solution, and a PVDF/SWCNT web was produced by electrospinning. To fabricate a polymer solution complex with a conductive material, it is important to understand the change in electrospinning behavior according to the properties of the solution. The properties of the composite solution were analyzed with respect to the SWCNT ratio in the solution, and the real-time effects on electrospinning behavior were compared and analyzed. The electrospinning behavior considerably differed depending on the properties of the solution. In this study, SWCNT was added in the range of 0–0.02%, and as the SWCNT content increased, the collection area decreased by 25%, the fiber diameter increased from 1.69 ± 0.88 to 1.83 ± 1.22 μm, and the PVDF fiber β-phase content reduced by approximately 6%. The PVFD/SWCN spinning behavior difference analysis and structure formation change according to the SWCNT ratio are useful for controlling the diameter, collection area, and crystallinity in the fiber process of PVDF. They are also expected to be useful for controlling the electrospinning behavior and fiber formation of various polymer materials based on the addition of conductive materials.
