“…[53,54] The high intensity of the C-N +• stretching vibration at 1337 cm -1 suggested that PANi in the composites was in the doped state. [55] Raman footprints of PEDOT:PSS (i.e. stretching deformation of Cβ-Cβ at 1372 cm -1 , Cα-Cα inter-ring stretching vibration at 1256 cm -1 , and oxyethylene ring deformations at 577 and 994 cm -1 ) [56] were all present in the GO/PA-PE composites.…”

Extrusion printing of interdigitated electrodes for flexible microsupercapacitors (fMSCs) offers an attractive route to the fabrication of flexible devices where cost, scalability, and processability of ink formulations are critical. In this work, highly concentrated, viscous, and water-dispersible inks are developed based on graphene oxide (GO)/polyaniline (PANi) composite for extrusion printing. The optimized GO/PANi-based all-solid-state symmetric fMSCs obtained by extrusion printing interdigitated microelectrodes can deliver outstanding areal capacitance of 153.6 mF cm-2 and volumetric capacitance of 19.2 F cm-3 at 5 mV s-1. It is shown that by fabricating asymmetric fMSCs using the GO/PANi as positive electrode and a graphene-based negative electrode, the voltage window can be widened from 0.8 to 1.2 V and improvements can be achieved in energy density (from 3.36 to 4.83 mWh cm-3), power density (from 9.82 to 25.3 W cm-3), and cycling stability (from 75% to 100% capacitance retention over 5000 cycles) compared with the symmetric counterpart. The simple ink preparation and facile device fabrication protocols reported here make the scalable fabrication of extrusion printed fMSCs a promising technology.

The interface formed between two immiscible electrolyte solutions (ITIES) constitutes a fantastic playground for the investigation of charge (under the form of either ion or electron) transfer processes. We have reviewed here the routes for the modification of such soft interfaces by an accurate electrochemical control. The three main strategies developed in the past four decades include (i) the electrochemically controlled assembly of molecules and nano-objects; (ii) the in-situ electrogeneration of nanomaterials and (iii) the use of ex-situ synthesised membranes. Applications of functionalized ITIES in the fields of redox catalysis and electroanalysis of modified soft interfaces are also discussed.

Abstract:The energy crisis and global warming are two of the greatest challenges that our societyi sf acing nowadays, requiring an immediate solution that involves the development of clean, efficient, sustainable and cheap energy-storage devices. These energy-storage devices are highly desirable for applications in electrical vehicles, portable electronic devices, and powerg rids, etc. The electrochemical performance of the devices largely depends on the chemical compositions and structures of the electrode materials. Graphene/polymer hybrid nanocomposites have gained great attention as electrodes for energy storage because of their excellent mechanical, electrical and electrochemical properties, originating from the synergistic effect of the two components.I nt his review,w ep resent ag eneral overview and recent advances of graphene/polymern anocomposites as high-performance electrode materials for supercapacitors. Major challenges to be tackled and future perspectives are also highlighted.
