Cellulose nanofiber (CNF) / polyolefin composite materials were successfully produced using diblock copolymers as polymeric dispersants. The copolymers were designed to have two segments selectively adhesive to each of CNF and matrix resins via noncovalent interaction. Hence, they mainly located at the CNF/matrix interface, achieving the homogeneous dispersion and high orientation of CNFs as well as the good interfacial interaction between CNF and matrix. We report that the mechanical properties of the CNF/HDPE composites were drastically improved by adding the polymeric dispersants.
