Abstract: | Soft wood (Ficus hispida) was chemically modified by impregnation of methyl methacrylate monomer, glycidyl methacrylate (GMA), a cross-linking agent,
and montmorillonite (MMT) using catalyst heat treatment. MMT was modified by using a polymerizable surfactant 2-acryloloxy
ethyl trimethyl ammonium chloride (ATAC) and a mixture of surfactants ATAC and cetyl trimethyl ammonium bromide (CTAB) in
a molar ratio of (1:1). A comparative study on different properties of the prepared wood polymer nanocomposite (WPNC) based
on impregnation of intercalating mixture containing MMA/GMA/clay modified by both the surfactants (ATAC and CTAB) and MMA/GMA/clay
modified by only surfactant ATAC were done. FTIR, XRD, and TGA studies were employed for the characterization of clay and
WPNC. WPNC prepared by using combined surfactant-modified clay along with MMA/GMA exhibited improved dimensional stability,
chemical resistance, thermal stability, mechanical properties, and lower water uptake than that of WPNC prepared by using
single surfactant-modified clay and MMA/GMA system. |
