Article
Lack of solution processability is the main bottleneck in research progression and commercialization of conducting polymers. The current strategy of employing a water-soluble dopant (such as PEDOT:PSS) is not feasible with organic solvents, thus limiting compatibility on hydrophobic surfaces, such as three-dimensional (3D) printable thermoplastics....
Article
Kirigami, the art of paper cutting, presents a promising approach for maximizing stretchability in planar sheets which is of paramount importance for the next-generation of wearable smart electronics. Current state-of-the-art Kirigami-based devices suffer from thin-film electrodes characterized by a limited surface area and poor electronic performa...
Article
Increasing capacitance and energy density is a major challenge in developing supercapacitors for flexible portable electronics. A thick electrode with a high mass loading of active electronic material leads to high areal capacitance; however, the higher the loading, the higher the mechanical stiffness and ion diffusion resistance, thereby hampering...

Fired brick is a universal building material, produced by thousand-year-old technology, that throughout history has seldom served any other purpose. Here, we develop a scalable, cost-effective and versatile chemical synthesis using a fired brick to control oxidative radical polymerization and deposition of a nanofibrillar coating of the conducting...

Microsupercapacitors (µSCs) are attractive electrochemical energy storage devices serving as alternatives to batteries in miniaturized portable electronics owing to high‐power density and extended cycling stability. Current state‐of‐the‐art microfabrication strategies are limited by costly steps producing materials with structural defects that lead...

Microsupercapacitors (μSCs) are electrochemical energy storage devices serving as alternatives to batteries in miniaturized portable electronics. In article number 2003394, Julio M. D'Arcy and co‐workers demonstrate a superior and cost‐effective route for developing 3D μSCs that directly convert Fe2O3 to poly(3,4‐ethylenedioxythiophene) (PEDOT) nan...
Article
Current state-of-the-art synthetic strategies produce conducting polymers suffering from low processability as well as unstable chemical and/or physical properties stifling research and development. Here, we introduce a platform for synthesizing scalable submicron-sized particles of the conducting polymer poly(3,4-ethylenedioxythiophene) (PEDOT). T...
Article
Freestanding, contiguous, and translucent polypyrrole nanonets are prepared within 90 minutes at room temperature in petri dishes by exposing aqueous oxidant to static pyrrole vapor. The nanonets are 150 nm thick, with variable densities depending on polymerization time. The nanonets maintain a low sheet resistance of 29.1 Ohm/sq at 30% optical tra...
Article
Iron corrosion, a product from the chemical reaction between iron and oxygen in the presence of water, and commonly referred to as rust, is a heterogeneous solid-state material comprised of multiple phases that represent an abundant source of chemical waste. Here, we introduce a strategy that advances the state-of-the-art in chemical synthesis by d...
Article
Here, we demonstrate a nanoengineering strategy that leads to an impact-resistant electrode for flexible energy storage devices such as supercapacitors resulting in state-of-the-art electrochemical performance. A template-less direct vapor synthesis produces a mat of poly(3,4-ethylenedioxythiophene) (PEDOT) 1D nanostructures. A nucleation-controlle...
Article
The diversity of nanostructures obtained from organic polymerization is limited when compared to the huge amount of documented inorganic nanostructures. In this paper, we elucidate a synergistic mechanism between in situ inorganic salt hydrolysis and vapor-phase polymerization for the metal oxide-poly (3,4-ethylenedioxythiophene) (PEDOT) hybrid nan...
Article
In this work, we introduce a novel condensing vapor phase polymerization (CVPP) strategy for depositing microtubes of the conducting polymer polypyrrole; these serve as one-dimensional hollow microstructures for storing electrochemical energy. In CVPP, water droplets are structure-directing templates for polypyrrole microtubes. Water vapor condensa...
Article
Covalent organic frameworks (COFs) represent an emerging class of porous crystalline materials and have recently shown interesting applications from catalysis to optoelectronic devices. In this review, by covering most of the reported work, we summarized the research progress of two-dimensional (2D) porphyrin- and phthalocyanine-based COFs, with hi...
Article
Covalent organic frameworks (COFs) represent an emerging class of porous crystalline materials and have recently shown interesting application in energy storage. Herein, we report the construction of cycle-stable sulfur electrode by embedding sulfur into a 2D COF. The designed porphyrin-based COF (Por-COF), featuring a relatively large pore volume...
