A recent study published in Journal of the Nigerian Society of Physical Sciences investigates how kaolin concentration affects the mechanical and thermal performance of plant-based furanโlignin foams. Six formulations containing 0โ2.5 g of kaolin were tested, with the 1.5 g formulation, KF4, showing the best overall performance. It achieved a compressive stress of 26.63 MPa, a density of 0.256 g/cmยณ, and thermal stability up to about 588.39 ยฐC. Microscopic analysis also revealed a refined and uniform cell structure. Lower filler levels provided insufficient reinforcement, while higher levels caused particle clustering and reduced performance. The findings highlight optimized kaolin loading as a promising route to stronger, heat-resistant, and sustainable bio-based foams.
