Implication

Experimental study demonstrates enhanced water resistance, strength, and fire retardancy in plant-based fiber foams, indicating potential for eco-friendly heavy packaging.

Key Points

  • To develop eco-friendly, multifunctional plant-based foams from sugarcane bagasse and bamboo fibers reinforced with AKD-coated hollow glass microspheres.
  • Incorporated alkyl ketene dimer (AKD)-coated hollow glass microspheres (HGMs) into sugarcane bagasse and bamboo fiber suspensions, followed by foaming and drying.
  • Tested performance variations using an optimized mixture of 10 g HGMs and 20 mL of 15 ± 0.5% solid-content AKD emulsion.
  • The optimized foam exhibited a Young’s modulus of 292.46 kPa, a compressive strength of 272.36 kPa, and a water contact angle of 139.4°.
  • Peak heat release rate (P-HRR) and total heat release (THR) decreased by 32.19% and 39.52%, respectively.
  • Limiting oxygen index (LOI) increased from 18.8% to 25.6%, alongside enhanced thermal stability and insulation.
