Mechanically Enhanced, Antibacterial, and Double‐Network Hydrogel Flexible Sensors for Sleep Apnea Monitoring

open access: yesSmall, EarlyView.
This report describes the preparation of an antibacterial hydrogel sensor from a polyvinyl alcohol/silk fibroin double network, tannic acid‐coated liquid metal, and copper particles, with an ethanol post‐treatment using a multi‐level structural regulation strategy. The obtained hydrogel is evaluated in the context of respiratory monitoring.

The Combined Effect of Gas Phase and Condensed Phase Mechanisms in Flame Retardancy of Polybutylene Succinate

open access: yesJournal of Vinyl and Additive Technology, EarlyView.
A combination of DOPO and APP flame‐retardants results in a V‐0 UL 94 rating. ABSTRACT In this study, we addressed the challenge of eliminating, during combustion, the flaming dripping behavior of polybutylene succinate flame retarded with ammonium polyphosphate, a key barrier to achieving a V‐0 rating in the UL 94 flammability test without excessive ...
