a Detail of CNCh films from left to right: AcCNCh film, EnCNCh film (obtained with LFACA-LPMO), EnCNCh film 1%wt rGO, 5%wt rGO and 10 wt rGO. EnCNCh is transparent and had good integrity unlike AcCNCh that was very weak and not as translucent. b Conductivity of EnCNCh for different reduced graphene contents: 0.3, 1, 2, 5, 10 and 15 wt% rGO (blue squares and blue line to guide the eye) and fitting (black line). Calculations were made with volumetric % of reduced graphene oxide. In the inset, a log-log plot for the determination of electrical percolation threshold of the material (Pc) (blue dots and fitting with blue line). c Image of 3D EnCNCh + 5% GO 3D printing of a stable honeycomb-like scaffold. d Picture of a EnCNCh + 5% GO 3D printed bottom shape scaffold where HEK293 cells were grown. e Confocal microscopy image at X10 of HEK293T-stained nuclei with DAPI and Orange Plasma seeded and grown on the hybrid material.
