Biomass and its lignocellulosic components are complex polymeric materials underutilized for their impressive mechanical properties. As the structural support material of plants, lignocellulosic biomass derives its strength and stiffness from the microscopic morphology of its cells, whose walls are composed of precisely aligned cellulose microfibrils known to have exceptional tensile properties. These microfibrils are reinforced by agglomerations of lignin and hemicellulose, making biomass a natural composite. However, as fluid transport is necessary even in the dead structural support tissue of plants, much of the volume of lignocellulosic biomass is void. Physical densification has been shown to improve its mechanical performance. Therefore, chemical densification, by way of selectively dissolving the non-cellulosic fraction of biomass in ionic liquid to form a cellulose-microfibril-reinforced biopolymer composite, should also yield improved mechanical properties. Unlike physical densification, this process is intrinsically scalable, as it is not limited by the size of feedstock particles.
