N2 - Growing concerns over the use of carcinogenic formaldehyde-based wood adhesives drive the need for sustainable alternatives. This study explores a novel nanocomposite adhesive made from canola protein isolate (CPI), reinforced with carbon nanotubes (CNTs) and graphene oxide (GO), to enhance bio-based adhesive performance. CNTs contribute mechanical strength, electrical conductivity, and thermal stability, while GO provides a large surface area, good dispersibility, and enhanced adhesion. The synergistic interaction between these nanomaterials significantly improves the adhesive properties of CPI. The study examined the impact of varying CNT-GO ratios on CPI’s adhesive strength under dry, wet, and soaked conditions. Results showed a positive correlation between increasing CNT-GO concentrations and adhesive performance. The adhesive strength markedly increased at a 0.5/0.5 (CNT/GO) ratio, especially in dry conditions. The optimal shear strength, however, was observed at a 0.3/0.7 ratio across all conditions. The thermogravimetric analysis confirmed that higher CNT-GO ratios enhanced the thermal stability of the nanocomposite, as indicated by increased weight loss percentages. This reflects improved resistance of the CPI matrix to thermal degradation. These findings highlight the importance of optimizing CNT-GO ratios for superior performance under diverse conditions. Overall, this study demonstrates the potential of CPI-CNT-GO nanocomposites as more sustainable alternatives to traditional formaldehyde-based adhesives, offering a promising solution to reduce the environmental and health risks associated with conventional wood adhesives.
