Synthesis and characterization of soluble, melt-processible aromatic poly(amide-imides)
… appropriate for the synthesis of aromatic poly(amide-imides). An evaluation of the relative merits and drawbacks of each method has also been made based on molecular, thermal and solid state characterization of the polymers. The synthesis of both high molecular weight as well as controlled …

Fabrication and characterization of poly(amide-imides)/TiO₂ nanocomposite gas separation membranes
… Ti0₂ rich domains were generated in-situ within poly(amide-imide) (PAl) and 6F-poly(amide-imide) (6FPAl) by a sol-gel process. The composite films showed a high optical transparency. The morphology of the Ti0₂ rich domains was observed by transmission electron microscopy (TEM). The Ti0₂ rich …

Poly(amide acid) infusion with Copper(II) Chloride to form polyimide microcomposite films
Polyimides are well known for their high thermal stability, chemical inertness, and their high electrical resistance. These properties make them ideal for use in the aerospace and electronics industries. Often polyimides are modified by coating or doping the films with metal species to change the …

Modification of polyamide thin film composite reverse osmosis membrane for water desalination
… membrane was prepared by the interfacial polymerization of m-phenylenediamine (MPD) and trimesoyl chloride (TMC) monomers on a porous polysulfone support. ZnO-graphene quantum dots (19 nm) were dispersed within the poly amide layer to create the quantum dots composite film. Comparison of …

Metal/polymer interactions
Polyimides by nature are highly resistive materials which exhibit exceptional thermal and chemical stabilities. Yet, there are a number of instances in which a polymeric material displaying low resistance and featuring similar physical, chemical, and thermal characteristics as polyimide would be …
