A correlation between the online during mixing measured conductance of carbon black (CB) filled silicone rubber and macrodispersion of CB determined by optical microscopy and microdispersion analysed by AFM has been established. The online conductance is a suitable tool to characterise the effect of technological parameters (e.g. rotor type, speed, mixing temperature) and material parameters (matrix viscosity, CB type and content) on the macro-and microdispersion directly during the mixing process. Thus, a modified method of the online conductance measurement can be used as the in-process method for monitoring the production process of electrical conductive polymer materials with low viscosity, e.g. liquid silicone rubbers.

“…The frozen matrix explains why the zero bias conductivity σ 0 is the same for all I– V curves below 174 K. Above 166 K, silicone is in the rubber state. The tunneling barriers can then expand under Joule heating 15, 19. This explains why σ 0 is halved in the 195 K and 206 K curves.…”

Tunneling Negative Differential Resistance in a Flexible Active Composite

A novel type of negative differential resistance (NDR) is demonstrated in composites incorporating graphite nanoparticles in a silicone matrix. The NDR occurs as the electric field breaks the π‐band of graphite, initiating a semimetal‐to‐insulator transition. The current peak is robust and tunable with the graphite concentration. This material can produce flexible electronic amplifiers for bioelectronic applications

“…Electrically conductive polymer composites have attracted lots of attention for widespread potential or practical engineering applications, such as switching sensors, self‐regulating heaters, circuit‐protection components, and electronic devices . These polymer composites consist of thermoplastic or thermosetting polymers and conductive fillers, such as graphite, carbon black (CB), carbon nanotubes (CNT), graphene, and other metal conductors . When a certain amount of the conductive fillers in the polymer matrix are added, the polymer composite will convert from an insulator to a conductor .…”

Polymer composites of low-density polyethylene/polypropylene/graphite/vanadium dioxide (LDPE 0.8 /PP 0.2 /Gr 0.4 /VO 2 ) are prepared by classical melt-mixing technology and show a notable double positive temperature coefficient of electric resistivity (PTC), which originates from the combined effect of highly conductive Gr and VO 2 with a thermal phase transition. When the weight ratio of VO 2 is 8 wt %, the positive temperature coefficient intensity (PTCI) for the composites reaches 3.85 orders of magnitude. The model system demonstrates the reason for the improvement in the PTC performance of the polymer composites by analyzing the construction of the conductive networks. Therefore, the addition of phase-transition compounds may be a promising path to improving PTC materials.
