Abstract
Intercalated poly(amide-imide) (PAI)/modified layered double hydroxide (LDH) nanocomposites (NC)s were synthesized by the solution intercalation method. Modified LDH was synthesized from the co-precipitation reaction of the Al(NO3)3 · 9H2O, Mg(NO3)2 · 6H2O and N,N’-(pyromellitoyl)-bis-valine under ultrasound irradiation. An optically active amino acid containing PAI was synthesized by direct polymerization reaction of chiral diacid and 3,5-diamino-N-(thiazole-2-yl)benzamide under green condition. The synthesized materials were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, thermogravimetric analysis (TGA), field emission scanning electron microscope (FE-SEM) and transmission electron microscopy (TEM) techniques. TEM and FE-SEM analysis confirmed that modified LDH was dispersed within the polymer matrix in intercalated and exfoliated forms.
