Abstract
The potential for simultaneously incorporating nano-copper oxide (CuO) while synthesizing phenol–formaldehyde (PF) resin using different concentrations of cupric chloride (CuCl2) was studied. Curing kinetics, resin morphology, as well as physical and mechanical properties of oriented strand boards produced using the modified PF resin were evaluated. Nano-CuO showed a positive effect on the PF resin curing reactions that was characterized by a significant decrease in the activation energy within conversion degree of 65%. X-ray photoelectron spectrometric analysis showed that bivalent CuO was present in the modified PF resin. Laser scattering particle analysis showed that more than 40% of CuO was in the nanoparticle range. Four types of nano-CuO crystal structures were observed. Incorporation of nano-CuO derived from a 40% concentration of CuCl2 into the PF resin gave a 74% increase in perpendicular MOR. 2-h thickness swelling of PCu-0.5 was improved significantly. The findings of this work have potential application to the engineered wood composites manufacturing.
