Summary: The laboratory-synthesized single-component intumescent flame retardant (IFR) was combined with phosphorus-containing polyhedral oligomeric silsesquioxane (P-POSS) as a novel synergist to prepare halogen-free flame-retarded polypropylene (PP) composite. The addition of only 1.0 wt-% loading of P-POSS significantly enhanced the flame-retarding property and mechanical performance of the composite, showing an efficient synergistic effect. The synergistic effect of P-POSS is attributed to the reinforcing effect of its decomposition products SiO2 and phosphoric acid-based compounds on char layers, while also improving filler dispersion and interfacial compatibility.

Incorporating CNTs decreased the mechanical performance of the printed part, but this decrease could be inhibited by increasing the laser energy density.
