Polydimethylsiloxane electrically conducting

Oil-in-oil emulsion systems display a relatively strong ER effect. Examples of such ER active emulsions are chlorinated paraffin/polydimethylsiloxane [11], castor oil/polydimethylsiloxane [13], urethane-modified polypropylene glycol/dimethylsiloxane [12] etc.. The ER effect in emulsions is attributed to the stretched droplets that Ibrm fibrillation chains along the direction of the electric field. This is a typical feature for any emulsion system in which the two liquids have a quite different dielectric constant and conductivity. Figure 17 shows the water droplet chains formed in a supercritical fluid carbon dioxide medium under a 60 Hz ac field of a very low field strength, Emax=IO V/mm [115]. A synergetic effect is observed in an system composing of polyanilines dispersed in a chlorinated paraffin/silicone oil emulsion [107],... 

The challenge was to fabricate the sensor (box) with two conductive membranes at each end, with air trapped between them (Fig. 11.21). This was solved using a nanocomposites of CNTs/PDMS (Sepiilveda et al., 2013a). Polydimethylsiloxane (PDMS) is a biocompatible silicone-based elastomer, with high degree of flexibility and elasticity, making it a suitable substrate for the stent application. However, it is not an electric conductor. This was solved by embedding into the PDMS substrate, carbon nanotubes...
