Rubberwood-polymer composites based on glycidyl methacrylate and diallyl phthalate

Abstract

Wood-polymer composites (WPC) of rubberwood (Hevea Brasiliensis) were prepared by impregnating the wood with glycidyl methacrylate (GMA), combinations of glycidyl methacrylate and diallyl phthalate (GMA-DAP), or diallyl phthalate (DAP) alone. Polymerization was carried out by catalyst-heat treatment. The results showed that WPC based on GMA exhibited greater dimensional stability (results of antishrink efficiency after six days of soaking) about five times than those based on DAP alone. Flexural [Modulus of Elasticity (MOE), Modulus of Rupture (MOR), and toughness], compressive, and impact properties for all the samples tested are improved, especially for those with higher chemical loading.

In situ polymerized wood polymer composite: effect of additives and nanoclay on the thermal, mechanical properties

“…Impregnation of woods with vinyl or acrylic monomers shows less dimensional stability in the presence of moisture 5 . Incorporation of cross linking material in wood sample provides better dimensional stability to the wood polymer composite 6,7 . Applications of nanotechnology to wood have been performed in recent years, for the conservation and restoration of the world's cultural heritage.…”

Development of new composites materials, carriers of active agents, from biodegradable polymers and wood

“…The first one consists in impregnating porous wood samples with the active agent [11][12][13][14], followed by the impregnation of e-caprolactone, which is polymerised inside the wood. PCL is supposed to fill the micro-channels of porous wood.…”

Enhancement of Physical and Mechanical Properties of Sugar Palm Fiber via Vacuum Resin Impregnation

“…Th is can be attributed to the hydrophilic property of natural fi bers where hydrogen bonding is formed between the hydroxyl groups and water molecules [31][32][33][34]. Th is is due to the fact that natural fi ber contains hydroxyl or OH groups, which are present throughout its structure and attract and hold water molecules by the mechanism of chemical bonding called hydrogen bonding.…”
