Electrospinning offers routes to develop new FR fibre solutions with improved mechanical properties, e.g. with multiple materials. Electrospinning is a known process for producing continuous polymer fibres, with diameters from 100 nm to 10 µm, or fibre mats. Injection...
3D printing enables new approaches to flame retardancy, such as surface layers or enclosure of FRs in structural voids. This review summarises different current FR solutions for different polymers and outlines AM (additive manufacturing) technologies:...
A review paper summarises recent progress in phosphorus PIN FRs derived from DOPO, replacing halogenated FRs. DOPO, 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide, offers thermal and chemical stability, oxidation resistance, and its O=P-H bond enables reaction...
PIN FRs, 3D DOPO (P-based) and ferrocene (Fe-based), reacted onto cotton provided durable fire resistance and waterproofing. Cotton fabric was first grafted with PEI (polyethyleneimine) then reacted in alcohol solution at 60°C with first ferrocene then DOPO...
PIN flame retardants show to be effective in PEAL, a composite material resulting from recycling of TetraPak packaging. PEAL is produced in Italy by collecting used TetraPaks with paper, processing to remove paper (which is recycled), then separation of impurities and...
