Abstract:
A liquid-phase stripping method was used to strip the graphite under the action of mechanical shear force to prepare graphene nanosheets (GNSs) on a large scale. Given the multicomponent composite conductive particles formed by GNSs with acid-treated MWCNTs (f-MWCNTs) and carbon black (CB), the three-dimensional (3D) intercalation electrothermal composite of GNSs/MWCNTs/CB with excellent conductivity and mechanical properties was prepared with water-based acrylic resin as a connector. Carbon particles (16.97 wt %) are found in the composite and the sheet resistance (Rs) is only 4 Ω sq-1 as f-MWCNTs and CB intercalations form a more stable 3D conducting medium between the GNSs. The flexible electrothermal film (2.5 cm × 2.5 cm) printed with the 3D intercalation GNSs/MWCNTs/CB composite had a saturation temperature (Ts) of 175 °C with an input of 3 V and lower power consumption (249.87 cm2 W-1). It only takes 10 s to reach Ts and the electrical performance is still intact under the pressure of 1 × 105 kPa. After being bent 2500 times (bending radius is 5 mm), the electrothermal performance of the flexible electrothermal film remained stable.
