Abstract Scope |
Pseudocapacitive energy storage materials are highly sought after due to their potential as electrode active materials in supercapacitors. However, their synthesis is typically complex and time-consuming. This article presents two studies that explore simple and scalable synthesis routes for conductive polymer polyaniline and 2D transition metal oxide. The first study utilized a reactive layer-by-layer deposition approach to synthesize polyaniline/polydopamine multilayer structures, combined with lithography patterning to create interdigital planar micro-supercapacitors. Control over the structure and properties was achieved by tuning the layer-by-layer process. The second study employed solid-phase synthesis by microwave irradiation. The mixture of iron chloride with GO produced more local microwave absorbent, which generated significant heat during treatment, facilitating the exfoliation of metal oxide and deoxygenation of GO. The resulting 2D Fe2O3/rGO composite materials exhibited promising energy storage properties and could be deposited on various substrates with patterning to form 2D MSC devices. |
