Tunable Plasma‐Polymerized Organosilicon Films for Toluene Sorption

open access: yesPlasma Processes and Polymers, Volume 22, Issue 9, September 2025.
This study demonstrates that plasma conditions during PECVD tune organosilicon film structure and toluene sensing, with rubbery films offering high sensitivity, strong selectivity for toluene over water, and excellent reversibility. These insights enable the tailored design of advanced materials for sensitive, selective detection of VOC contaminants in
