Special Issue Information

Dear Colleagues,

Polymers have become an important and ubiquitous part of our lives. However, most polymers, irrespective of their source, are inherently flammable; thus, they pose a threat to life and property. The 21st century has witnessed some of the most devastating fire accidents in history, necessitating a new and innovative approach to polymer-related fires. To reduce the thermally hazardous nature of polymeric materials, flame-retardant polymeric materials have undergone rapid development in recent decades. In order to meet different application scenarios, attempts to manufacture sustainable and efficient flame-retardant polymers and additives with multiple functions have been made.

This Special Issue aims to gather scientific papers focusing on recent advances in the synthesis and application of flame-retardant polymeric materials. Contributions on all themes are invited, including but not limited to novel flame retardants, flame-retardant polymers, multifunctional flame-retardant polymers, and the investigation of flame-retardant mechanisms. Original research articles, review articles, short communications, and perspectives presenting and discussing the most recent trends in these areas are welcomed.

In this study, a ternary hydrogen (H)-bonded complex intumescent flame retardant (TH-IFR) of melamine (ME) · phosphoric acid (PA)…pentaerythritol (PER) was synthesized through hydrothermal reaction. The combination of the synthesized TH-IFR with 4A molecular sieve as the synergist was used for the first time to improve the flame retardancy of polypropylene (PP). The involved structure, morphology, flame retardancy, flame-retarding mechanism and mechanical properties of the prepared PP composites were systematically investigated. The results show that incorporation of 1 wt% synergist 4A shows the optimum synergistic effect, and the flame retardancy and mechanical properties of the flame-retarded (FR) PP composites are significantly improved. Incorporation of 4A could change the pyrolysis process of the entire system and promote the char-forming chemical interaction, thereby further enhancing the flame retardancy of FR PP composite. The synergistically flame-retarding mechanism of 4A is explained by the significantly improved quality and quantity of the solid-phase char layer, which is formed through generation of SiO2 and Al2O3 substances, and also participation of PP macromolecular chains in the final char layer formation during burning. Furthermore, the improved dispersion and compatibility of TH-IFR in the composite is largely beneficial to the improvement of flame retardancy and mechanical properties. Full article
