The nano-ZIF-8@GO hybrids were synthesized and blended with poly(lactic acid) (PLA) by solution method. The effect of nano-ZIF-8@GO hybrids on the crystallization was investigated by DSC and POM. The results showed that low addition amount of nano-ZIF-8@GO had a significant influence on the crystallization behavior of PLA. The tensile strength and elongation at break of the PLA/ZIF-8@GO nanocomposites with 0.5 wt% of ZIF-8@GO were increased to 49.63 MPa and 24.10% compared with 35.83 MPa and 17.66% of the pure PLA, respectively. The addition of nano-ZIF-8@GO hybrids also enhanced the flame retardancy of PLA, and the mechanism was proposed.
