“…Common strategies include the dispersion of functionalised carbon nano-tubes, carbon black, and graphene [9, 10], or the use of conductive polymers (e.g., polyaniline, polythiophene) [11], or by dispersion of metal salts (e.g., phosphonic groups) [11], or oligomers (e.g., tetraaniline) [12]. Besides enabling ESD protection, with proper formulation, the normal manufacturing process of PU foams allows generating flexible shapes facilitating the cushioning customisation [8]. Due to this versatility, flexible foams, such as PU, have been used extensively as a packaging and supporting material of highly sensitive equipment such as ESDS.…”
