Preparation and characteristics of cellulose nanowhisker reinforced acrylic foams synthesized by freeze-casting
Abstract
Directional freeze-casting of acrylic latex with a cellulose nanowhisker (CNW) suspension was investigated as a novel technique for preparing an acrylic-based nanocomposite foam. Compared with the control acrylic foam, the nanocomposites showed significantly improved mechanical and thermal properties, which were mainly due to the oriented and continuous channel architectures and high functionality of CNWs.
