Abstract

The performance of CNTs with different amounts and dispersion states were explored in the flame retardant system as PBS/APP. Herein, A series of CNTs wrapped ammonium polyphosphate (named CAPP) were successfully prepared and characterized, and then blended into Poly(butylene succinate) (PBS) as an additive-type flame retardant. The obtained PBS/CAPP contributes to forming much more graphitized char layers to reduce the heat transfer and toxic gases release. For instance, PBS-3 containing 20% CAPP1 wrapped by only 1% of CNTs shows the best anti-dripping effect and the lowest toxic gases release, where CO2 and CO yield dramatically reduced by about 68.3% and 72.6%. With the same content of CNTs, the tensile strength, elongation at break and unnotched impact strength of PBS-3 increased about 10.8%, 14.2% and 5.3% than PBS-5 (CNTs added directly). Thus, the well dispersion state of moderate CNTs has a positive impact on improving mechanical properties, flame retardancy and smoke suppression.
