The use of silicone polymers for insulation has helped to build electric machines and apparatuses which can operate for a long time at 180-200 °C and for a limited period of time at 450-500 °C and higher. Owing to the high moisture resistance of silicone polymers, electric engines with silicone insulation can operate for a long time even underwater. The experience shows that the application of silicone insulating materials helps to considerably reduce the size of machines and increase the time of their... 

The focus here on self-organizing polymers, electrical and optical properties, and biosynthesis is not even close to comprehensive in the enumeration of avenues and opportunities in new polymeric materials. Degradable plastics that do not remain in our environment forever [24] and polymer precursors to ceramics [19] and inorganic fibers are two of many more areas in which new polymeric materials will provide new challenges to engineers in production and processing.

It is known that the catalyst layer is far from uniform, especially in the case of a gradient catalyst layer. Thus, profiling properties, such as conductivity, in the catalyst layer are important. Both an electronic conductor (carbon) and an ionic conductor (Nafion ) exist in the catalyst layer, which can be considered a conductive polymer. The conductive polymer electric circuit model has been applied to the catalyst layer, and an ionic conductivity profile was obtained [8], as shown in Figure 4.33. 

Solution parameters such as viscosity of solution, polymer concentration, molecular weight of polymer, electrical conductivity, elasticity and surface tension, those are which attribute to polymer and its solution charaeteristies has important effect on morphology [18]. 

A more direct route to making polymer lasers would be to excite the polymers electrically in a diode structure. Although polymer LEDs have been made in which the injected carrier density matches the threshold excitation density of the best photopumped polymer lasers, a polymer diode laser has not yet been made. The threshold for diode lasers is higher because the electrodes that must be incorporated to the structure increase the waveguiding loss. In addition, for some... 

When the two tables are compared it is evident that there is a wide choice in fillers which either enhance or retain dielectric properties of polymers. It is more difficult to formulate conductive polymers where consideration must be given to how the filler can change properties of the polymer. Electrically conductive polymers can be divided into three groups ... 

Relative humidity readings are obtained from a device containing a polymer that swells when it becomes moist. The swelling causes an increase in the electrical resistance of a carbon layer in the polymer. Electrical measurements of the resistance of the material indirectly measure changes in relative humidity.

The presence of dispersed fillers in the polymer material in low amounts may intensify electrization, increase the residual charge and change the friction coefficient. Introduction of the filler in the electret state exerts a still stronger effect on polymer electrization on frictional interaction with metals. Depending on the direction of the field intensity vector formed by the filler particles, the field generated by triboelectrization can be attenuated or intensified. This means that the principle of the electret-triboelectrization superposition is realized [49], which can be used to regulate the parameters of frictional interactions. Thus, by the introduction of the electret filler, e.g. mechanically activated F-3 powder, it is possible to decrease the friction force (Fig. 4.9).
