Abstract

Three different kinds of nanoparticles (nano-Al2O3, nano-SiO2, and nano-CaCO3) were incorporated into a thermoset polyurethane adhesive. The influence of the type of nanoparticle and concentration on nanoadhesives mechanical, rheological properties, and dispersion degree was analyzed. It was found that as nanoparticle concentration increases tensile strength and Young’s modulus increases. However, there was a maximum concentration from which mechanical properties were reduced. Nanoadhesive mechanical properties were controlled by nanoparticles specific surface area, hardness, and surface treatment. In addition, it was found that the addition of nanoparticles accelerates nanoadhesives curing rate.
