Preparation and properties of carboxylated styrene-butadiene rubber/cellulose nanocrystals composites

► We explore using CNs to reinforce XSBR matrix for preparation of a nanocomposite. ► CNs could form a strong filler network in the XSBR matrix. ► Good compatibility and interfacial adhesion between XSBR and CNs. ► Significant increase in tensile strength and tear strength with increasing CNs.
