제목 New Millable Polyurethane/Organoclay Nanocomposite: Preparation, Characterization and Properties
초록 This paper highlights the preparation and the properties of the millable polyurethane/organoclay nanocomposite. For the previous preparative route to silicate/polyurethane nanocomposites, the approach was to physically mix alkyl- or aromatic-modified silicate with polyurethane prepolymer or polyurethane urea polymer in appropriate solvents. In the present study, the millable polyurethane/organoclay nanocomposite is prepared by mechanical mixing followed by the vulcanization method. Wide angle X-ray diffraction was used to determine the extent of intercalation of the polymer chains into the silicate layers of the clay. Both storage modulus and tensile strength increase with increasing organoclay loading. Tensile strength, 100% stress and elongation at break were higher for the nanocomposites than for their individual components.
