ABSTRACT Conjugated polymers are effective dispersants of SWNTs which also impart their properties onto polymer‐SWNT complexes. By modifying the polymer sidechain, the properties of the complex can be fine‐tuned for targeted applications. Here, we introduced pillar[5]arenes containing pendant quaternary ammonium groups onto the polymer side chains using strain promoted azide‐al…

ABSTRACT The widespread development of proton exchange membrane water electrolyzers (PEMWEs) is severely impeded by the scarcity of iridium‐based anodic catalysts. While non‐noble transition metal oxides (TMOs) (e.g., cobalt spinels) offer a cost‐effective alternative, they suffer rapid structural collapse in harsh acidic environments due to lattice oxygen over‐oxidation and su…

ABSTRACT Polyimide (PI) microwave absorption (MA) foam characterized by its superior electromagnetic protection performance and adjustable mechanical properties, is considered a quintessential structure‐function integrated material. Currently, the expressed low compressive strength (∼kPa) of PI MA foam matrix limits application as a direct load‐bearing component, despite potent…

ABSTRACT Vacuum deposition of perovskite thin films offers superior conformality and precise control over solution‐based methods. However, non‐uniform nucleation and island‐like growth produce columnar grains, voids, and trap states at the electron‐transport layer (ETL)/perovskite interface, causing non‐radiative recombination. In conventional co‐deposition, volatile formamidin…

ABSTRACT InSe is a highly promising material for the next‐generation nanoelectronics due to unique optoelectronic and electronic performance. However, the presence of intrinsic defects plays a detrimental role in InSe field‐effect transistors (FETs) and photodetectors, which causes carrier scattering and degrades performance. Herein, we demonstrated an efficient Ag doping strat…
