| Résumé : |
Nanocomposites containing montmorillonite (layered silicate clay) and SiO2 particle were prepared via in-situ polymerization. The effect of synthesis conditions, such as surfactant and SiO2 content, on the application properties of nanocomposite were investigated in details. Nanocomposite, which used hexadecyl trimethyl ammonium chloride as the surfactant, had the best application properties. The incorporation of SiO2 was favored for improvement of wet-heat resistance temperature of the leather, in contrast to the nanocomposite without SiO2. Nanocomposite facilitate the absorption of chrome. Fourier transform infrared spectroscopy (FT-IR) spectrum demonstrated that methacrylic acid was polymerized in the montmorillonite inter-lamellar and nano-SiO2 was completely copolymerized with methacrylic acid monomers. X-ray diffraction (XRD) results suggested that montmorillonite layers were exfoliated during the polymerization process. |
