Polypropylene (PP) is a semicrystalline polyolefin built from propylene units, whose methyl side groups fix the chain conformation and therefore the tacticity, the crystallinity and the melting point. Isotactic chains pack into a helical lattice, atactic chains stay amorphous, and the balance between the two sets stiffness and toughness. Electrical properties of polypropylene nanocomposites follow from the dispersion of the filler and from the crystallinity of the matrix [1]. Carbon nanomaterials change the structure and the conductivity of the polymer while its processability is retained [2]. Gaseous plasma treatment of non-woven polypropylene alters the surface energy without changing the bulk [3].
