“…In recent decades, researchers have concentrated their efforts on imbuing polymer foams: polyurethane, polystyrene, rubber, phenol-formaldehyde, epoxy, and polyethylene polyolefin foams with new functions by incorporating various types of particles that exhibit a wide range of remarkable properties. [1][2][3][4][5][6][7] Because of their extraordinary compressibility, stretchability, and flexibility, they are used for several applications. In aerospace, petrochemical, thermal and acoustic insulation, and other fields, phenolic foam material exhibits exceptional performance characteristics.…”
