Different weight amounts of graphene oxide (GO) were solution-dispersed with the precursor of polyimide (PI) and poly(amide-imide) (PAI) to synthesizen PI/GO or PAI/GO composite films after the imidization process. The addition of trimellitic anhydride chloride (TMAC) in PAI/GO matirx provides the interaction between amide group on PAI and carboxy/hydroxyl groups on GO.The effects of TMAC and G...

The term 'aramid fibre' refers to a manufactured fibre in which the fibre-forming substance is a long-chain synthetic polyamide with at least 85% of the amide linkages attached directly to two aromatic rings (Preston, 1978; Yang, 1993). 'para-Aramid fibres' are those in which the amide Iinkages are in the para (l,4) positions on the aromatic rings. para-Aramid fibres of poly(para-phenyleneterep...

Ferulic acid (FA), a bio-based resource found in fruits and vegetables, was coupled with a hydroxyl-amino acid to generate a new class of monomers to afford poly(carbonate-amide)s with potential to degrade into natural products. l-Serine was first selected as the hydroxyl-amino partner for FA, from which the activated p-nitrophenyl carbonate monomer was synthesized. Unfortunately, polymerizatio...

PVP (poly(vinyl pyrrolidone)) is a common polymer that behaves as a surface-regulating agent that shapes metal nanocrystals in the polyol process. We have used different polymers containing tertiary amide groups, namely PVCL (poly(vinyl caprolactam)) and PDMAm (poly(N,N-dimethyl acrylamide)), for the synthesis of gold polyhedrons, including octahedrons, cuboctahedrons, cubes, and higher polygon...

We demonstrate how multimode 2D IR spectroscopy of the protein amide I' and II' vibrations can be used to distinguish protein secondary structure. Polarization-dependent amide I'-II' 2D IR experiments on poly-l-lysine in the beta-sheet, alpha-helix, and random coil conformations show that a combination of amide I' and II' diagonal and cross peaks can effectively distinguish between secondary st...
