“…It was evident that clays were homogeneously dispersed in the SAN polymer matrix present in the cell wall of wood. The homogeneous distribution of clay silicate layers in MUF/clay impregnated aspen wood composites was also reported by Cai et al 8 .…”

“…Nanoclay treated samples showed lower water absorption compared to silane treated samples. The silicate layers of the clay generated the tortuous pathway and increased the barrier property for diffusion of water within the composites 8 . Wood samples treated with the combination of nanoclay and silane showed least water absorption.…”

“…Applications of nanotechnology to wood have been performed in recent years, for the conservation and restoration of the world's cultural heritage. Impregnation of melamine urea formaldehyde (MUF) and phenol formaldehyde (PF) prepolymer containing hydrophobic nanofillers into wood has improved significantly surface hardness, modulus of elasticity and water repellency 8,9 . It is well documented that the loading of clay into polymer enhances mechanical, barrier and flame retardant properties.…”

This study concerns the preparation and characterization of wood polymer nanocomposites based on impregnation of styrene acrylonitrile co-polymer-nanoclay intercalating system in presence of glycidyl methacrylate (GMA), a cross linking agent, and vinyl trichloro silane (VTCS) as additives into Simul (Bombex ceiba, L.), a soft wood. The effect of nanoclay and VTCS on the properties of the resultant wood polymer nanocomposites (WPNC) has been evaluated. FTIR spectroscopy shows the interaction among wood, polymers, GMA, nanoclay and VTCS. The penetration of polymer and nanoclay into the wood cell wall is supported by SEM study. The distribution of nanoclay in the SAN polymer matrix present within the wood cell wall has been evidenced by TEM study. TGA results show an improvement in the thermostability of the resultant composites. The inclusion of VTCS enhances the self extinguishing behaviour of the WPNC as revealed by limiting oxygen index (LOI) test. Due to treatment, the resultant WPNC exhibits an improvement in all the properties like water repellancy, dimensional stability, hardness, flexural, tensile and thermal stability compared to untreated wood.

a Carbon fibers were synthesized using a low-cost, economical method. Fresh rubber wood fibers (Hevea brasiliensis) were burned using a furnace in an inert condition at 350 to 450 o C for 2-4 hours, and after that the fibers were ground at 18000 rpm for 20 to 40 seconds. The effect of carbon fibers as a reinforcement agent on mechanical, physical, and morphological properties was investigated. In the composite preparation, carbon fiber dosages (0, 0.1, 0.25, and 0.5 wt.%) were used as variable factors, along with a urea formaldehyde content of 10%. The morphology of the specimens was characterized using X-ray diffraction (XRD), Thermogravimetric analysis (TGA), and Field Emission Scanning Electron Microscopy (FESEM). The mechanical tests indicated that when carbon fibers were added, the modulus of rupture (MOR) and internal bonding strength (IB) improved significantly. From the TGA graph it was observed that the thermal stability of the composites based on carbon fiber was higher than composites without it. The thermocouple readings showed that at a higher loading of carbon, the core temperature of the board increased faster than for the control board.

“…Barrier properties, fire resistance and mechanical properties are of great importance for the successful application of selected wood products. However, few efforts based on such technology have been made in the formation of wood polymer composite (WPC), to improve such properties so as to meet specific end-use requirements (Cai et al, 2008;Devi & Maji, 2011). It seems to be a promising way to further improve the comprehensive performance of wood.…”
