In this way, the material mimics the excitatory response of pressure-sensing neurons in the human skin. The composites, formed of silicone and graphitic nanoparticles, were prepared in several allotropic forms and functionalized with naphthalene diimide molecules. A systematic study is presented of the negative differential resistance (NDR) region of the current-voltage curves, which is responsible for the material?s active properties. This study was conducted as a function of temperature, graphite filling fraction, scaling to reveal the break-up of the samples into electric field domains at the onset of the NDR region, and an electric-field induced metal-insulator transition in graphite nanoparticles. The effect of molecular functionalization on the miscibility threshold and the current-voltage curves is demonstrated. Room-temperature and low-temperature measurements were performed on these composite films under strains using a remote-controlled, custom-made step motor bench. 410 0$aSpringer theses. 606 $aSilicones 606 $aNanoparticles 606 $aGraphite 615 0$aSilicones. 615 0$aNanoparticles. 615 0$aGraphite. 676 $a530.41 700 $aLittlejohn$b Samuel David$01062869 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910300382703321 996 $aElectrical Properties of Graphite Nanoparticles in Silicone$92528831 997 $aUNINA
