Chlorinated poly electrical conductivity

The UV absorption spectrum of this carbonized polymer is shown in Fig. 3.43. This black polymer has an electrical conductivity of lOScm" [554-556]. Complex conductive patterns can be directly drawn onto the film made from chlorinated poly(vinyl chloride) (Fig. 3.45) [557]. 

In practice, highly conductive particles do not make good ER fluids, in part because of excessive conduction in the resulting suspension. An acceptable conductivity of the particles seems to be around 10 f2 m (Block et al. 1990), at least for particles of the polymer poly(acenequinone) in chlorinated oil. These ER fluids show a yield stress of about 1 kPa at E = 1 kV/mm, roughly equal to the predicted maximum possible value for this electric field. As expected, even higher yield stresses exceeding 10 kPa are possible when E exceeds 3 kV/mm.
