Polyamide nanocomposites containing hydrazide–hydrazone group reinforced with functionalized polyethyleneimine modified Mg(OH)₂ nanoparticles: Study on thermal properties, combustion resistance, and lead ion adsorption

Polyamide nanocomposites (PANC) were prepared from an aliphatic–aromatic polyamide (PA) containing hydrazide–hydrazone groups in the side chain, reinforced with functionalized polyethyleneimine (FPEI)/modified Mg(OH) 2 nanoparticles (FPMN). For this purpose, a new structure, aromatic diamine (DAHH), containing the hydrazide–hydrazone group, was synthesized, and used to synthesize PA by direct polycondensation. Also, polyethyleneimine (PEI) was...
