Multi-component polymer systems comprising wood as bio-based

Wood-thermoplastic composites WPCs which also have been called wood-plastic composites have experienced significant development in the recent decades Clemons et al. 2013 . They are usually manufactured through mixing the natural bio-based component with the thermoplastic polymer or its addition to the polymer matrix followed by processing under high pressure and temperature conditions.

Chinese Reinvent Wood by Replacing Lignin with Resol

Natural polymer lignin makes natural wood strong. Lignin binds small crystallites of cellulose together in a web-like structure. Chinese scientists replaced lignin with synthetic polymer resol. Resol is a synthetic polymer that has a web-like structure and can bind crystallites together to create strength. The crystallites can be changed to create different types of wood colours and properties.

Improved colour durability is obtained by using lignin free fibres which do not suffer from the typical wood greying effect. The best colour durability is achieved if the deck has a high performance plastic cap on the surface so long as the right quality of UV stabilizers and colour pigments have been used.
