Thermoplastic polyurethane (TPU) copolymers are interesting host matrices for the incorporation of conductive carbon black (CB) particles. The two-phase character of the TPU systems provides an opportunity for the CB particles to distribute nonuniformly within the phases, owing to their different characteristics. Thus, in spite of its highly polar nature, the TPU/CB system percolates at a relatively low CB content. The CD presence affects the TPU two-phase structure, resulting in a large change of its low temperature loss modulus. CB-containing extruded filaments produced by a capillary rheometer at various shear rates were studied as sensing materials for different alcohols. All ...
