Abstract

In this study, the effects of multi-walled carbon nanotubes (MWCNTs) added to urea-formaldehyde (UF) and melamine-urea-formaldehyde (MUF) adhesives on the physical and mechanical properties of particleboards were investigated. Particleboards were produced by adding MWCNTs at concentrations of 0.5 %, 1 %, and 1.5 % to the adhesives, and their properties were evaluated. The addition of MWCNTs improved water absorption (WA), thickness swelling (TS), modulus of rupture (MOR), modulus of elasticity (MOE) in bending, and internal bond (IB) strength. The best results were observed at 1.5 % MWCNT for UF adhesive and 1 % MWCNT for MUF adhesive. Fourier-transform infrared spectroscopy (FTIR) revealed enhanced chemical bonding within the adhesive matrix, while thermogravimetric analysis (TGA) demonstrated improved thermal stability of the composites. Statistical analysis using response surface methodology (RSM) confirmed the impact of MWCNT content and adhesive type on the performance of the boards. The findings of this study indicate that MWCNTs are promising additives for developing high-performance, durable, and sustainable wood-based composites.
