Summary: Controlling charge transport properties and morphologies of CP films is crucial for the practical application of CP-based OFET sensors. A processing strategy involving SVA and PNs significantly enhanced charge transport and surface-to-volume ratio of CP thin films. The PN2-P3HT films showed improved charge transport and surface-to-volume ratio after SVA, resulting in excellent responsivities and rapid response/recovery times in VOC detection by OFET sensors.

Summary: Organic p-type cathode materials have gained attention for their higher redox potentials and rate capabilities. However, most of the p-type cathodes based on one-electron redox still have limited stability and low specific capacity. In this study, two polymers, CPP and NCPP, containing two-electron redox dihydrophenazine, were developed as p-type cathode materials. The results show that the conjugated linkage in CPP is more favorable for charge delocalization and oxidation at higher potentials, leading to a higher reversible specific capacity of 184 mAh g(-1) and excellent cycling stability.

Summary: Polymer-inorganic nanocomposites based on polymer-grafted nanocrystals (PGNCs) are being used in technologically relevant applications due to their unique physical, chemical, and mechanical properties. This study demonstrates a kinetically controlled assembly of binary superstructures from a homogeneous disordered PGNC mixture using solvent vapor annealing (SVA), providing insight into the multistep crystallization pathway of PGNCs. By varying the solvent vapor pressure during SVA, exquisite control of the rate and extent of PGNC assembly is achieved, allowing for the synthesis of multicomponent PGNC superstructures with multifunctionalities and emergent properties.

Summary: The study proposes a Se heteroatoms incorporated CoWS2 (Se-CoWS2) as anode and banana flower skin-derived activated carbon (BFS-AC) as cathode for energy storage application. The Se-CoWS2 modified nickel foam (NF) exhibits lower charge transfer resistance, higher specific capacity, and long-term stability. The asymmetric device (Se-CoWS2//BFS-AC) delivers a satisfactory energy density at a high power density and retains a high Coulombic efficiency even after continuous charge/discharge cycles. The study highlights the potential of heteroatom incorporation with metal chalcogenides and the use of biomass-derived carbon for better charge balance in asymmetric configuration.

Summary: Self-healable elastomeric materials have been synthesized and used to improve the gas barrier properties of packaging films. Hexa-layer assemblies consisting of inorganic nanoplatelets and oppositely charged polyelectrolytes were developed by sequential depositions. Layer-by-layer technique was then applied to reduce the water vapor transmission rate of the films. The self-healable barrier films recover their initial properties after mechanical damage, and encapsulated organic light-emitting diodes have significantly longer half-lifetime values. This research develops transparent, stretchable, and self-healable gas barrier films for flexible electronic device packaging applications.

Summary: The applicability of nanofillers in gel polymer electrolyte (GPE)-based devices has significantly increased in the past decade. However, the development of their applicability in GPE-based electrochromic devices (ECDs) has been limited due to challenges such as optical inhomogeneity, transmittance drop, and poor electrolyte fabrication methodologies. In this study, a reinforced polymer electrolyte tailored through PVDF-HFP, BMIMBF4, and various types of mesoporous SiO2 nanofillers was demonstrated to address these issues.

Summary: The recently emerged metal-halide hybrid perovskite (MHP) has excellent optoelectronic features and has attracted great attention in various applications. However, achieving an electrically driven laser has been challenging due to the degradation of perovskite and other limitations. In this work, we observed an ultralow-threshold optically pumped laser from moisture-insensitive perovskite micro-plates and demonstrated an electrically driven laser by combining suitable perovskite/hole transport and electron transport layers. Our discovery opens up new possibilities for future optoelectronics.
