【 摘 要 】

Poly(lactic acid) (PLA) synthesized from renewable resources has drawn a great deal of interest in packaging,electronics and automotive applications. However, poor flame retardancy of PLA, especially its ease of ignitability and heavilyflaming drips, represents a major obstacle for its potential application. The article outlines the recent advances in thefield of flame-retarded PLA. Current development trends based on the direct incorporation of flame retardant additives,chemical modification, hybridization and synthesis of flame retardants were reported. Results obtained from UL 94 verticalburning, limiting oxygen index (LOI) and cone calorimetry (CCM) tests for each type of flame retardants were discussedand analyzed. Test results summarized in a UL 94-LOI matrix found to be a useful tool to determine the effectiveness offlame retardants in PLA. The UL 94-LOI comparison matrix and CCM test results revealed that the combined use of flameretardants (containing intumescent formulation) is one of the promising strategies to reach the flame retardancy of PLAneeded by practical applications. This review ends with a brief summary of and outlook on future developments of flameretardedPLA systems.
