ABSTRACT
A novel multiwalled carbon nanotube/polypropylene (CNT/PP) conductive fibrous membrane with fiber diameter of 1–3 μm was fabricated by melt electrospinning. To improve the dispersibility CNT and enhance spinnability PP fibers, CNTs were first mixed small amounts paraffin liquid (PL) then melt-blended for The morphology membranes orientation in fibers observed via scanning transmission electron microscopy (SEM TEM). effect PL on crystallization behavior studied differential calorimetry (DSC) X-ray diffraction (XRD). Tensile test impedance analysis performed to investigate mechanical electrical properties membranes. results indicated that has a distinct nucleating PP, addition can CNT/PP compound remarkably. This electrospinning exhibits improved tensile strength modulus, good electric conductivity, enhanced dielectric constant hydrophobicity.
