“…IL interfaces are particularly important for interface-controlled applications such as sensor [4,[16][17][18][19], lubrication [20][21][22], separation [4,19,[23][24][25][26][27][28][29], electrochemistry [4,19,[30][31][32][33][34][35][36][37][38][39] and electronics [40][41][42] technologies. ILs further stimulated completely new concepts for catalysis [1,4,[43][44][45][46][47][48][49][50][51][52][53][54][55][56][57].…”

The interface of ionic liquids (ILs) with solid surfaces is of pivotal interest for many applications, ranging from sensors, lubrication, separation technology, and electronics to electrochemistry and catalysis. We present a short review on ultrathin layers of ionic liquids on metal surfaces using a surface science approach. We mainly focus on specific examples of imidazolium-based ionic liquids on Ag(111) and Au(111) studied by angle-resolved X-ray photoelectron spectroscopy, and relate the obtained results to existing literature. We address a variety of phenomena on the molecular level, namely, (i) the adsorption, growth and wetting behavior of ILs, (ii) the thermal stability and desorption of ILs, (iii) exchange processes of anions and cations at the IL/solid interface, and (iv) the replacement of ILs from the IL/solid interface by porphyrins.

“…The use of organic electronic materials as the active electrode in batteries and supercapacitors, hold promise for several key-features of relevance for the growing need of electrical energy storage, such as (i) replacing expensive and rare inorganic materials, (ii) avoiding the limitation of material abundance, (iii) providing low costs, and (iv) potentially environmentally friendly energy solutions. (1,13) Within the field of organic electronics, two classes of materials hold the most promise for energy storage applications by providing sufficient conductivity and capacity; carbon based-materials (14)(15)(16) and conductive polymers (17)(18)(19). The focus of the researcher presented herein is on conductive polymers.…”

Demands in the storage of energy have increased for many reasons, in part driven by household photovoltaics, electric grid balancing, along with portable and wearable electronics. These are fast-growing and differentiated applications that urge for large volume and/or highly distributed electrical energy storage, which then requires environmentally friendly, scalable and flexible materials and manufacturing techniques. However, the limitations on current inorganic technologies have driven research efforts to explore organic and carbon-based alternatives. Here, we report a conducting polymer:cellulose composite that serves as the active material in supercapacitors which has been incorporated into all printed energy storage devices. These devices exhibit a specific capacitance of ≈ 90 F/g and an excellent cyclability (>10,000 cycles). Further, a design concept coined 'supercapacitors on demand' is presented, which is based on a printing-cutting-folding procedure, that provide us with a flexible production protocol to manufacture supercapacitors with adaptable configuration and electrical characteristics.

“…This peak shift implies that the composition of ILs results in structural conformation change of doped PEDOT chains from benzenoid to quinoid structure with more planar chain conformation beneficial for denser molecular packing, which can be attributed to IL-induced doping level changes. [21] Meanwhile, the PEDOT:PSS films with the TCB-based ILs show notable growth in the PSS peak compared to those with the anion-modified ILs. This trend is clearly observed in the 1D scattering profiles along both the in-plane and out-ofplane directions (Figure 3h,g).…”
