The article introduces a simple and scalable strategy to prepare cellulose-based multifunctional foam materials through physical cross-linking and stabilization. The foam exhibits low density, enhanced flame-retardant performance, low thermal conductivity, good acoustic insulation property, and good mechanical properties. It can also be recycled. This novel foam material is highly significant for modern engineering construction applications.
The development of eco-friendly and good-performance foam materials is essential for the environment and energy saving. Conventional inorganic and organic foams suffer from brittleness and contamination problems. Here, we report a facile and scalable hybrid strategy to prepare shape-stable cellulose-based multifunctional foam via physical cross-linking of PVA and stabilization of HGMs. The prepared foam exhibits ultra-low density (27.0 mg/cm3), enhanced flame-retardant performance (the PHRR decreased from 161.8 to 89.1 kW/m2, LOI value up to 26.2%), low thermal conductivity (48.2 mW/mK), good acoustic insulation property (NRC of 0.41), and good mechanical properties (with specific compressive modulus of 15.3 MPa cm3/g). Moreover, the foam can be recycled under simplified procedures. Our approach provides a novel alternative to the manufacture of low-cost, eco-friendly, and scalable foam materials. This multifunctional lightweight material is highly sought after for modern engineering construction applications.
