Abstract Dye structure intercalated layered double hydroxide (d-LDH) was synthesized using one-step method and its intercalated behaviors have been characterized by spectroscopy (FTIR), wide angle X-ray scattering (WAXS), scan electron microscopy (SEM), thermogravimetric analysis (TGA), etc. As novel functional potential fire retarding nanofiller, it was used to prepare polypropylene-grafted maleic anhydride (PP-g-MA)/d-LDH composite by refluxing the mixture of d-LDH and PP-g-MA in xylene, aiming to investigate its effect on the flammability of PP-g-MA composite. The morphological analysis, thermal stability, and flame retardant properties of PP-g-MA/d-LDH composite were carried out by FTIR, WAXS, transmission electron microscopy (TEM), TGA, and microscale combustion calorimetry (MCC), respectively. Compared with NO3-LDH (unmodified LDH) and LDH intercalated by sodium dodecylbenzenesulfonate (SDBS) (conventional organomodified LDH), d-LDH can decrease significantly heat release rate (HRR) and the total heat release (THR) of the PP-g-MA composite, offering a new approach to impart the low flammability for LDH-based polymer composites.
