Novel CMPL sensors enhance flame retardancy and thermal response for improved fire detection systems.
Key Points
This research aims to develop a new fire-warning sensor that combines rapid response, durability, and flame-retardant properties using cellulose and MXene materials with liquid metal.
Fabricated CMPL films through layer-by-layer assembly of MXene/cellulose gel and liquid metal layers.
Integrated CMPL films into a circuit for performance testing with a thermal stimulus from an alcohol lamp.
Conducted mechanistic studies to analyze fire warning mechanisms and performance characteristics.
CMPL films demonstrated a 65.1% reduction in peak heat release rate compared to CM films.
Displayed ultrafast thermal response with recovery times of ~4 seconds and ~2 seconds.
Resistance changed over 30 orders of magnitude within the fire-warning response period, indicating high sensitivity.
