Special Issue Information

Dear Colleagues,

The aim of this special issue is to highlight the most recent advances in applications of flame-retardant materials, including: fundamentals of the preparation, characterization, performances in view of the urgent requirement to multifunctional fire-safety polymeric materials.

The large-scale application of polymeric materials is often accompanied by fire hazards. Nowadays, the function of most flame retardants is relatively simple, meanwhile, the introduction of flame retardants usually deteriorates the self-performance of polymeric materials. To meet the requirements, the development of alternative multifunctional flame retardants and flame-retardant materials has attracted widespread attention.

We invite the research community to contribute to this Special Issue by submitting comprehensive reviews or original research articles. The topics of interest include, but are not limited to, the following:

  • New fire retardants and synergists;
  • Bio-based or biomass flame retardants;
  • Flame-retardant coating;
  • Multifunctional performances;
  • Advances in flame-retardant characterization techniques
  • Flame-retardant mechanisms;
  • Smoke, toxicity, and environmental impact.

Waterborne polyurethanes (WPUs) have attracted great interest owing to their environmentally friendly properties, and are wildly applied in production and daily life. However, waterborne polyurethanes are flammable. Up to now, the challenge remains to prepare WPUs with excellent flame resistance, high emulsion stability, and outstanding mechanical properties. Herein, a novel flame-retardant additive, 2-hydroxyethan-1-aminium (2-(1H-benzo[d]imidazol-2-yl)ethyl)(phenyl)phosphinate (BIEP-ETA) has been synthesized and applied to improve the flame resistance of WPUs, which has both phosphorus nitrogen synergistic effect and the ability to form hydrogen bonds with WPUs. The WPU blends (WPU/FRs) exhibited a positive fire-retardant effect in both the vapor and condensed phases, with significantly improved self-extinguishing performance and reduced heat release value. Interestingly, thanks to the good compatibility between BIEP-ETA and WPUs, WPU/FRs not only have higher emulsion stability, but also have better mechanical properties with synchronously improved tensile strength and toughness. Moreover, WPU/FRs also exhibit excellent potential as a corrosion-resistant coating. Full article
