The effect of adding graphene oxide to urea formaldehyde resin and its efficacy on three layered particleboard

Abstract

The research for improving adhesives and the properties of wood composites is always important for industry. The aim of this study is investigating the effect of adding graphene oxide in the UF resin on the functional properties of particleboard panels with an average thickness of 16 mm. The influence of graphene oxide content (0; 0,25 %; 0,5 % and 0,75 % based on the dry weight of the UF resin) and pressing time (4 and 5 minutes) on the internal bonding, bending strength, modulus of elasticity and dimensional stability were studied. The results showed that the use of graphene oxide in the UF resin caused an improvement of the mechanical and physical properties of the particleboards. Also, comparing two different pressing times, the boards made by 4 minutes with graphene oxide is preferred without negative effect on the functional properties of particleboards.
