The observed dependence of the optimal electrical response at a value of 2 vol. %, But the response is still unstable. The introduction of additional filler ( dispersed tin or graphite ) provides greater stability in response to the action of mechanical effort. The influence of the chemical nature of the polymer matrix leading to the formation of phases formed dispersed filler. We studied the mechanical and electrical properties of such systems and the level of touch response when exposed to alternating mechanical loads. Optimal conditions for the formation of tracks that provide the maximum level of sensory response . It has been shown that irradiation of multilayer carbon nanotube array , an additional thermomechanical treated at 800 ° C, will result in lower coefficient of elasticity and conductivity of the material at about 2 times. The effect is due to the formation of radiation defects that reduce the concentration of conduction electrons. Established that the electrical conductivity and density nanotube array at which the insulator-metal transition is equally influenced by both radiation and primary defects. But the coefficient of elasticity is basically just pour radiation defects . Therefore, driven by changes in the concentration of primary defects can offset the impact of irradiation on the electrical conductivity, which is important for the use of the material in the space environment. Also found that the addition of nanotubes in an array of micro-particles of copper reduces the deformation inelastic processes . For the first time the opportunity of using laser irradiation not only to change the density of the array of carbon nanotubes , but also for the diagnosis of carbon nanomaterials . The conclusion about the possibility of preparing a patent for using satellite accelerometer controlled sensing element with optimum transfer function .
