Description
Kawalerczyk and team chemically decorated nano-fiber, plant fiber shrunk to nanoscale, in three varied ways and stirred each version into the glue used for board. Urea-formaldehyde adhesive dominates board making, and nano-fiber can strengthen it, but surface chemistry decides compatibility. Their 2026 study acetylated, phosphorylated, or sulfonated the fibers, verified each change chemically, then pressed boards and tested glue behavior, heat stability, strength, and swelling.
Acetylated nano-fiber shortened glue setting time, while the other two versions thickened the glue most in the reported readings. Phosphorylated fiber gave the adhesive the highest heat resistance in thermal analysis. Boards with acetylated fiber achieved the best internal bond strength and were the only modified variant to clearly improve bending strength and stiffness. Swelling in thickness also fell with acetylated fiber. Kawalerczyk concludes surface treatment, not just fiber addition, unlocks the gains.
