Novel PTFE/CNT composite nanofiber membranes with enhanced mechanical, crystalline, conductive, and dielectric properties fabricated by emulsion electrospinning and sintering

Polytetrafluoroethylene/multiwalled carbon nanotubes (PTFE/CNT) nanofiber membranes were prepared by emulsion electrospinning and high temperature sintering. Compared with pure PTFE nanofiber membranes, at low CNT content, the mechanical properties of PTFE/CNT nanofiber membranes were improved. For example, the tensile strength of PTFE/CNT (0.5 wt%) composite nanofiber membranes increased from 2.5 MPa to 5.92 MPa, and the elongation at break...
