Fire safety mechanisms of metal polymeric nanoarchitectures for extreme environments
摘要
Due to the high flammability behavior of polymeric matrices during fire outbreaks and their escalating demand in construction of buildings, aerospace, automobiles, maritime and oil and gas infrastructures, the quest to eliminate their inherently high flammability has become very critical in these segments. Nanotechnological emancipation has enabled the integration of metal nanoparticulates (NPs) (iron, cobalt, nickel, and zinc), rare transitional metallic fire retardants (titanium, zirconium, and molybdenum) as well as main group metals (magnesium and aluminum), within polymeric matrices to form metal polymeric nanoarchitectures (ME@PNC) with enhanced flame retardant (FR) features for aforementioned and other vast range of applications. Furthermore, increasing advent of expert researches have resulted in the emergence of FR metal organic frameworks (MOFs) with outstanding features used in constructing MOF polymeric nanoarchitectures herein referred as MOF@PNC nanoarchitectures. Therefore, this paper examines FR mechanisms and emerging routes in attaining fire safety and improved mechanical features of ME@PNC with insight into MOFs@PNC and prospective applications.
