dc.abstract.enWhile nanocellulose (NC) has already shown potential in enhancing urea-formaldehyde (UF) adhesives, further studies are needed on the effects of functionalized NC on adhesive and particleboard properties. This study evaluated the effect of unmodified and lysine-functionalized NC on the properties of UF adhesive and particleboard performance. NC modification was confirmed using Fourier-transform infrared spectroscopy (FTIR) and amino group quantification. Thermogravimetric analysis (TGA) showed that functionalized NC degraded at lower temperatures but had improved stability at higher temperatures. Differential scanning calorimetry (DSC) indicated that NC slightly shifted the curing process to lower temperatures and increased the curing enthalpy. NC addition increased adhesive viscosity, with loading having a greater effect than functionalization. Unmodified NC enhanced the overall strength of the particleboard, but did not affect water resistance or formaldehyde content. However, functionalized NC significantly improved internal bond strength, short-term water resistance, and reduced formaldehyde emissions. The optimal NC loading was 1%, as increasing it to 1.5% brought no further improvements. These findings suggest that functionalized NC can be an effective additive for enhancing UF adhesive performance in particleboard applications.
