Previous research has shown that the inclusion of the spherical silica (SiO 2 ) nanoparticles into epoxy resin can achieve simultaneous improvement of fracture toughness and modulus. However, the glass transition temperature of the nanocomposite was significantly decreased when loading the nanosilica was higher than 5wt.%. This perhaps was caused by utilization of the ultrasonication probe...
Polymer–clay nanocomposites are of great interest due to their improvement in certain material properties relative to virgin polymer or conventional composites. For example, compared to conventional materials, Nylon 6/montmorillonite nanocomposites demonstrated significant improvements, including high strength, high modulus and high heat distortion temperature. Because viscoelastic measurements are...
Polystyrene clay nanocomposites can be prepared via several different methods, including in situ polymerization, melt compounding, or solvent blending. In this paper, we investigate solvent blending which is facilitated by high power sonication to prepare an exfoliated polystyrene-clay nanocomposite. The effects of clay type as well as sonication during solvent blending in regards to degree of clay...
