Impedance spectroscopy, X-ray diffraction, infrared dichroism and AFM imaging were used to investigate the effect of orientation and doping on the electrical properties of a series of stretched poly(phenylene vinylene) (PPV) films. The degree of orientation was determined by infrared dichroism. X-ray diffraction patterns clearly display a transition from random orientation to a high degree of orientation...
In this study, composites consisting of an insulating poly(acrylonitrile-co-butadiene-co-styrene) polymer matrix and a conducting carbon black (CB) additive were produced by twin-screw extrusion. Both direct current and alternating current electrical measurements were used to evaluate the electrical properties of the composite and to assess whether sufficient mixing was achieved. Electrical measurement...
