By using multiwalled carbon nanotubes, starch and softwood, researchers have synthesized a green wood nanocomposite that is thermally stable and flame retardant, making it potentially useful for home and industrial applications1.
Wood polymer composites made from petroleum-based polymers and solvents are not biodegradable and could pollute the environment. To prepare an ecofriendly wood nanocomposite, the researchers mixed modified multiwalled carbon nanotubes with starch, the softwood Kalmou (Ipomoea carnea) and water.
The carbon nanotubes significantly enhanced the wood nanocomposite’s mechanical properties, such as its tensile strength and hardness. The wood nanocomposite attained such mechanical properties due to the formation of strong chemical bonds between surface hydroxyl groups of the carbon nanotubes and methyl groups in the softwood.read more
