High-performance carrageenan film based on carrageenan intercalated layered double hydroxide with enhanced properties: Fire safety, thermal stability and barrier effect

Bio-based polysaccharides show potentials to substitute petroleum-based polymers. Herein, κ-carrageenan intercalated layered double hydroxide (LDH-Carra) was prepared to impart κ-carrageenan film with improved thermal stability, fire safety and gas barrier. Results showed that the temperature at 5% mass loss of carrageenan film with 3 wt% LDH-Carra (Carra/LDH-Carra) was increased by 55 °C. Carra/LDH-Carra presented 42.9% and 52.0% reduction of...
