A study was conducted on the properties of plywood based on a urea-formaldehyde binder with the addition of multi-stage carbon nanotubes (MWCNTs). The key objective was to investigate the effect of f-MWCNT concentration on the physical, mechanical, thermal, and environmental characteristics of the resulting materials. A comprehensive analysis using TEM, Raman, and FTIR spectroscopy confirmed the successful introduction of carboxyl groups onto the nanotube surface. The strength properties (MOR and MOE) of the plywood reached their maximum at a content of 1.5% f-MWCNTs, increasing by 62.7% and 113%, respectively, compared to the control sample. Water resistance improved with increasing filler concentration, demonstrating the best result at 4% f-MWCNTs. The results of this study demonstrate the high efficiency of using functionalized MWCNTs to create plywood with an improved range of properties.
