Tailoring the surface morphology and nanoparticle distribution of laser-induced graphene/Co3O4 for high-performance flexible microsupercapacitors

Simple fabrication of Co3O4 nanoparticles on N-doped laser-induced graphene for high-performance supercapacitors

“…15 Therefore, efforts have been made to modify the LIG surface by heteroatom doping (N, S, B, and P), [16][17][18] functionalization, 19 and producing hybrid composites with pseudocapacitive materials. [20][21][22] For instance, heteroatom-doped LIG electrode material exhibited signicantly improved capacitive performance compared with pristine LIG, as previously reported by our research group. 18 The integration of heteroatom-doped LIG with pseudocapacitive material is also a viable strategy to boost the electrochemical performance of SC electrode materials.…”

Laser fabrication of functional micro-supercapacitors

“…The photothermal effect of laser can not only carbonize and graphitize the specified substrates, but also can induce many photo-thermal/chemical reactions to produce the diversified materials [212]. Zang and colleagues ablated the gelatin/metal-ion (Mo 5+ , W 6+ and Co 2+ ) matrix with a CO 2 laser to fabricate the ultrathin carbides (MoC x , WC x , and CoC x ) through the Buoyancy Marangoni effect (Fig.…”

Research Progress of Graphene-Based Flexible Humidity Sensor

“…The key to their manufacture lies in the flexibility of the electrodes/circuits. At present, the theoretical research on the design and manufacturing of graphenebased flexible electronic devices mainly focuses on the flexible substrate transfer method and the strain structure design method, as shown in Figure 1 [74,75]. The flexible substrate transfer method is a method for sequentially transferring one electrode structure to another flexible substrate.…”
