This review presents the recent developments in research hotspots of advanced functional polymers; their concepts, design strategies, and applications are briefly discussed.
Abstract A sulfur‐linked carbonyl‐based poly(2,5‐dihydroxyl‐1,4‐benzoquinonyl sulfide) (PDHBQS) compound is synthesized and used as cathode material for lithium‐ion batteries (LIBs). Flexible binder‐free composite with single‐wall carbon nanotubes (PDHBQS–SWCNTs) then fabricated through vacuum filtration method SWCNTs. Electrochemical measurements show that PDHBQS–SWCNTs can deliver a discharge capacity of 182 mA h g −1 (0.9 cm −2 ) at current rate 50 potential window 1.5 V–3.5 V. The...
Despite the fact that lithium-sulfur batteries are regarded as promising next-generation rechargeable battery systems owning to high theoretical specific capacity (1675 mA h g-1) and energy density (2600 W kg-1), several issues such poor electrical conductivity, sluggish redox kinetics, severe "shuttle effect" in electrodes still hinder their practical application. MXenes, novel two-dimensional materials with regulable interlayer spacing, abundant functional groups, widely applied storage...
Abstract Ternary architecture is a promising strategy to further boost the performance of organic solar cells (OSCs).

Chiral supramolecular architectures deliver desired properties and functions to artificial systems. The recently developed direct circularly polarized light (CPL) detection is based on electronic devices with chiral active layers that inform photocurrent dissymmetry (gsc) upon illuminations of opposing CPL. Due limited absorption (gabs) in the layers, exploring prospect creating additional gsc becoming increasingly relevant. In particular, rationalizing corresponding amplification mechanisms...
Transfer of molecular chirality to supramolecular at nanoscale and microscale by chemical self-assembly has been studied intensively for years. However, how such further transfers the macroscale along same path remains elusive. Here we reveal from level macroscopic via self-assembly. We assemble a macrostripe using enantiomeric camphorsulfonic acid (CSA)-doped polyaniline with hierarchical order. The stripe can twist into single-handed helical ribbon self-motion. A multi-scale...

Although lithium metal is an ideal anode with high theoretical capacity, Li dendrite formation and volume change have limited its application. We report a vertical polyaniline nanowire-coated carbon nanotube (CNT/PANI) composite flexible electrode on which could be homogeneously deposited to obtain CNT/PANI@Li anode. In the composite, CNT/PANI acted as host matrix well-distributed ion flux attributed electroactive surface area, thereby effectively suppressing dendrite. Compared pure CNT...
