NANOPARTICLES DISPERSION IN PROCESSING NANOSTRUCTURE CHIRAL POLY(AMIDE-IMIDE)S BASED ON 7V-TRIMELLITYLIMIDO-Z,-LEUCINE/TiO2 NANOCOMPOSITES: ALLOCATION AND PROPERTIES
Poly(amide-imide)s (PAI)s as engineering materials have received more attention owing to their high thermal and chemical stability. Therefore, organic/ inorganic nanocomposite (NC) of these materials has been widely studied in the last few decades. Here, we present PAI-NCs preparation containing sur...
