Moving Beyond Oligoethers: Polar Side‐Chain Engineering for Aqueous Mixed Ionic–Electronic Conductors

Advanced Functional Materials, EarlyView.
We investigate how side‐chain chemistry and hydrogen bonding affect electrochemical doping in poly(propylenedioxythiophene) polymers. Replacing oligoether side chains with hydroxyl or carboxylic acid groups nearly triples electrochemical conductivity.

Tuning Separator Chemistry: Improving Zn Anode Compatibility via Functionalized Chitin Nanofibers

Advanced Functional Materials, EarlyView.
Nanochitin derived from waste shrimp shells is used to fabricate separators for aqueous zinc batteries. By tuning the density of amine and carboxylic surface groups, water mobility at the separator interface is controlled, promoting uniform zinc deposition, suppressing dendrite growth, and enabling exceptional cycling stability exceeding 2000 h ...
