Carbohydrate Polymers, Journal Year: 2025, Volume and Issue: 357, P. 123435 - 123435

Published: Feb. 25, 2025

Engineering porosity levels in hierarchical cryogels presents an exciting opportunity for advancing electromagnetic interference (EMI) shielding materials. This study introduces a feasible approach to tailoring micro-scale morphology cellulose nanofiber (CNF)-based by simply adjusting the freeze-templating temperature, resulting tunable and enhanced performance characteristics. By varying we successfully controlled pore size (ranging from 31 178 μm), which influenced mechanical strength (decreasing 59 14 kPa). To explore effect of on EMI performance, rendered CNF conductivity upon integrating poly(3,4-ethylenedioxythiophene) (PEDOT) with framework via chemical vapor polymerization. Our results demonstrate that larger sizes promoted absorption-dominant mechanism, average absorbance (A) 0.59 across X-band frequency range. A specific effectiveness (SSE/t) 4801.25 dB cm2 g-1 was achieved samples porosities, highlighting decent these engineered cryogels. findings reveal straightforward yet effective strategy optimizing achieve appreciable effectiveness, contributing advancement sustainable, high-performance solutions.
