ABSTRACT Lignin‐layered double hydroxide (lignin‐LDH) complex was synthesized by in situ method, and then styrene‐butadiene rubber (SBR)/lignin‐LDH composites were prepared by the melt compounding method. X‐ray diffraction analysis showed that crystal lignin‐LDH was successfully obtained and transmission electron microscopy analysis showed well dispersion of lignin‐LDH in SBR matrix. The tensile strength, elongation at break, 300% modulus and hardness of lignin‐LDH/SBR were significantly improved compared to LDH/SBR composites. Thermogravimetric analysis indicated that the thermal degradation temperature of the lignin‐LDH/SBR at 10% weight loss ( T 10 ) decreased whereas 50% weight loss ( T 50 ) was much higher than that of pristine LDH/SBR due to barrier property of the well dispersed Lignin‐LDH in SBR matrix. © 2013 Wiley Periodicals, Inc.
