Abstract
This contribution relates new information on the properties of electrically conductive, processible Ni(Pc)/polymer/I2 hybrid materials. Both the temperature and composition dependence of the electrical conductivity of Ni(Pc)/Kevlar/I2 fibres are strongly reminiscent of the behaviour of composites. Using a variant of our fibre spinning methodology, it is also possible to produce Ni(Pc)/Kevlar/I2 ribbons. Polarized resonance Raman spectroscopy indicates that the ribbons are structurally anisotropic (Ni(Pc)I c axes are preferentially aligned in the extrusion direction), while four-probe transport measurements indicate significant anisotropy in the conductivity ( σ{norm of matrix} σhu ≈ 8 where {norm of matrix} denotes the extrusion direction). This anisotropy is nearly temperature independent. Electrically conductive fibres can also be prepared using Nomex or poly(p-phenylene-2,6-benzobisthiazole) (PBT) instead of Kevlar as the host polymer.
