Bio-based chitosan supramolecular shell enabling synergistic flame retardancy and anti-aging in polypropylene.
Commercial intumescent flame retardants (IFRs) effectively reduce the flammability of polypropylene (PP) but significantly deteriorate its weather resistance. Although hindered amine light stabilizers (HALS) can improve UV-aging resistance, their intrinsic acid-base antagonism with IFRs limits their combined applicatio...
