“…In the literature, the reduction in the number of stacked layers in GNP is attempted through a variety of techniques, namely, intercalation, oxidization, heat treatment, microwave irradiation, and ultrasonic treatment. [21][22][23][24] A wide range of applications is envisaged for GNP, from sensors 25 and electromechanical resonators 26 to adsorbents. [27][28][29] GNP deserve increasing interest also as filler for polymers, 30 and reviews are already available on processing 18 and mechanical and electrical properties 31 of the ensuing polymer nanocomposites.…”
