Abstract

The multifunctional properties of carbon nanotubes (CNTs) as nanofiller in polymer matrix have necessitated the development of adhesives with improved bond strength, and water resistance. However, good dispersion and interfacial interaction between adhesive matrix and carbon nanofiller is essential to obtaining the aforementioned properties. An environmentally friendly adhesive to replace formaldehyde and petrochemical adhesive was prepared from soy protein isolate (SPI) by incorporating CNTs as reinforcement. Sonication with mechanical (shear) stirring was a simple and effective approach to obtain the adhesives with rather uniformly dispersed CNTs in the SPI matrix. Characterization technique employed was scanning electron microscopy which showed the homogeneous dispersion of CNTs in SPI using two mixing methods (shear mixing and sonication/mixing). In addition, Fourier transmission infrared (FTIR) spectroscopy was used to analyze the surface functionalities and the type of functional group on the surface of the adhesive nanocomposite. Thermogravimetry analysis (TGA), gave the percentage weight loss and thermal stability of the samples. The result showed that sonication with 30 minutes of mixing gave a homogenous dispersion more than in shear mixing only.
