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.
