Abstract
Softwood was chemically modified by impregnation with melamine formaldehyde-furfuryl alcohol (MFFA)
copolymer, dimethylol dihydroxyethylene urea (DMDHEU) and organically modified nanoclay. A decrease in the
crystallinity index value was obtained, as determined by Fourier Transform Infrared Spectroscopy (FTIR) and X-ray
diffractometry (XRD). Scanning electron microscopy (SEM) and Transmission electron microscopy (TEM) were used
for the characterization of the nanocomposites. The nanocomposites (WPNC) showed enhanced dimensional stability,
chemical resistance, flame retardancy and higher mechanical properties. The UV resistance property of WPNC
increased considerably as judged by the rate of weight loss, carbonyl index, lignin index, crystallinity index values,
SEM and mechanical properties.
