A cross‐linking strategy can result in a three‐dimensional network of interconnected chains for the copolymers, thereby improving their mechanical performance. In this work, a series of cross‐linked conjugated copolymers, named PC2, PC5, and PC8, constructed with different ratios of monomers are designed and synthesized. For comparison, a random linear copolymer, PR2 is also synthesized based on the...
Aliovalent doping is widely adopted to tune the electronic structure of transition‐metal oxides for design of low‐cost, active electrocatalysts. Here, using single‐crystalline thin films as model electrocatalysts, the structure‐activity relationship of Fe states doping in perovskite LaNiO3 for oxygen evolution reaction (OER) is studied. Fe4+ state is found to be crucial for enhancing the OER activity...
Multiwalled carbon nanotube/polymer composites with aligned and isotropic micropores are constructed by a facile ice‐templated freeze‐drying method in a wide density range, with controllable types and contents of the nanoscale building blocks, in order to tune the shielding performance together with the considerable mechanical and electrical properties. Under the mutual promotion of the frame and...
Chemical vapor deposition (CVD) growth of high‐quality graphene has emerged as the most promising technique in terms of its integrated manufacturing. However, there lacks a controllable growth method for producing high‐quality and a large‐quantity graphene films, simultaneously, at a fast growth rate, regardless of roll‐to‐roll (R2R) or batch‐to‐batch (B2B) methods. Here, a stationary‐atmospheric‐pressure...
The increasing demand of electronic devices for physical motion detection has encouraged the development of highly elastic strain sensors. Especially, to capture wide‐range physical movements, supremely stretchable and wide‐range strain sensors are required. Here, a novel transparent, bendable, stretchable, and wide‐range strain sensor based on a sandwich‐like stacked graphene and Ag‐nanowires hybrid...
