Abstract
Exfoliated graphite oxide embedded into a polysiloxane matrix can be simply obtained by sonochemical approach. These nanocomposites show an electrical conductivity depending on the applied stress and have most of crucial characteristics of an electrical pressure transducer (absence of electrical hysteresis, prompt resistivity variation, etc.). The highest sensitivity for these electrical devices is obtained with exfoliated graphene oxide concentration just a little inferior to the percolation threshold (that is, 5.5wt.% of graphene).File in questo prodotto:
