Surface Wrinkling of Plasma‐Exposed PDMS is Caused by Water Vapor Sorption: An Optical Environmental Sensor

open access: yesAdvanced Functional Materials, EarlyView.
Wrinkling of soft materials, such as polydimethylsiloxane (PDMS), underpins a myriad of technologies. Plasma‐oxidation of PDMS induces spontaneous wrinkling, which is canonically attributed to thermal expansion‐contraction of bilayers. Employing experiments and modelling, it is demonstrated that sorption of water vapor is instead responsible for ...

Advanced Flame Retardant Strategies and Fire Performance Assessment for Safer Photovoltaics in Buildings: A Two‐Part Review

open access: yesAdvanced Functional Materials, EarlyView.
The integration of photovoltaic (PV) systems into building structures introduces distinct fire risks with critical implications for occupant safety. This review examines the key fire hazards associated with PV implementation and explores mitigation strategies, including flame‐retardant additives.

Mimicking Synaptic Plasticity: Optoionic MoS2 Memory Powered by Biopolymer Hydrogels as a Dynamic Cations Reservoir

open access: yesAdvanced Functional Materials, EarlyView.
Janus (MoS2) transistors functionalized with sodium alginate (SA) and poly(vinylidene fluoride‐co‐trifluoroethylene) [P(VDF‐TrFE)] exhibit persistent photo‐induced ionic gating, driven by dynamic cation migration at the hybrid interface. This ionic mechanism enables finely tunable photoconductivity and emulates key synaptic plasticity behaviors ...
