Insertion of novel optically active poly(amide-imide) chains containing pyromellitoyl-bis-l-phenylalanine linkages into the nanolayered silicates modified with l-tyrosine through solution intercalation

In the present investigation, for the first time, functional optically active poly(amide-imide) (PAI)/organonanosilica bionanocomposite films were successfully fabricated through solution intercalation technique. At the start, Cloisite Na+ and

Surface functionalized Tio 2 nanoparticle designed for the preparation of chiral poly(amide-imide) bionanocomposites containing phenylalanine linkage

The surface of titanium dioxide (TiO2) nanoparticles was treated with a silane coupling agent of γ-aminopropyl-triethoxy silane. An optically active poly(amide-imide) (PAI) was synthesized by the indirect polycondensation reaction of the L-phenylalanine b
