Layered Double Hydroxide Nanocomposite Coatings for Improved Flame Retardancy of Polyethylene-Based Copolymers.

ABSTRACT: This work proposes a coating approach for obtaining flame-retardant ethylene-vinyl acetate (EVA) and ethylene-butyl acrylate (EBA) copolymer-based materials. Nanocomposite films of EVA and EBA were first produced by cast extrusion, with two types of layered double hydroxides (LDHs) differing in the aspect ratio used as nanofillers. Subsequently, the films were applied as a coating to the corresponding neat copolymer substrate, and the combustion behavior of the so-obtained samples was evaluated through cone calorimeter tests. Despite the small amount of nanofillers (0.5 wt.% considering the whole specimen), the application of the coatings significantly improved the time to ignition compared to the pristine copolymers, while the shape of the heat release rate curves and the relative peak va
