Non‐Monotonic Changes in the Thermal Conductivity of Conjugated Polymer Films with Increasing Levels of Chemical Doping

Advanced Functional Materials, EarlyView.
Thermal conductivity changes non‐monotonically as regioregular (RR) and regiorandom (RRa) P3HT films are doped with F4TCNQ as a function of the extent to which P3HT is doped: an increase in thermal conductivity is observed upon lightly doping P3HT compared to the undoped film, followed by a decrease in the heavily doped regime. ABSTRACT The performance

Embedded Ferroelectric Nanoclusters Can Drive Polarization Reversal in a Non‐Ferroelectric Polar Film via the Proximity Effect

Advanced Functional Materials, EarlyView.
Ferroelectric nanoclusters create local internal fields in a normally non‐switchable polar film because of polarization mismatch at their interfaces. That field opposes polarization in the regions with larger polarization and reinforces polarization in the regions with smaller polarization.

A Novel Modified Petroresin Particle (MPRP) With Enhanced Oil–Water Selectivity for Cold Production in Heavy Oil Reservoirs

Advanced Functional Materials, EarlyView.
A novel oil–water selective conformance control agent, MPRP, is prepared via hydrophilic grafting and mechanical granulation. MPRP uniformly disperses in water, cohesively expands upon aging, and readily dissolves in the oil phase. During conformance control, it selectively aggregates in water channeling pathways to form effective plugs without ...

Ionic Precursors Transformed Into Vinyl Acetate Synthesis Catalyst via Reaction‐Driven Restructuring

Advanced Functional Materials, EarlyView.
This work demonstrates that a simple physical mixture of Pd and Au ionic precursors, KOAc promoter, and SiO2 support can transform into a highly active vinyl acetate synthesis catalyst through reaction‐driven restructuring. The results highlight reaction‐induced restructuring as an innovative and sustainable catalyst design strategy.

Hierarchical Primary‐Secondary Coordination Synchronizes Ion Flux and Sulfur Redox in Solid Polymer Electrolytes

Advanced Functional Materials, EarlyView.
Hierarchical coordination engineering redistributes Li+ from anion‐dominated pairing toward polymer‐mediated binding. Strong primary sites promote salt dissociation, while distributed secondary sites sustain dynamic hopping pathways. This coordination landscape couples ion flux with polysulfide conversion, suppresses transport‐conversion decoupling ...
