Abstract Among the high-performance and engineering polymers, polyimides closely related polyetherimide (PEI) stand out by their capability to react with nucleophiles under relatively mild conditions. By targeting phthalimide groups in chain backbone, post-functionalization offers a pathway adjust surface properties such as hydrophilicity, solvent resistance, porosity. Here, we use ultrathin PE...

In this work, different sizing agent aqueous dispersions based on polyetherimide (PEI) were elaborated in order to improve the interface between carbon fibers and a thermoplastic matrix (PEEK). The dispersions were obtained by the emulsion/solvent evaporation technique. To optimize the stability and the film formation on the fibers, two surfactants were tested at different concentrations, with ...

A novel approach for production of polyetherimide (PEI) microparticles by liquid–liquid phase separation (LLPS) and precipitation is demonstrated the effect used solvents acetophenone dimethyl phthalate on obtained powders outlined. Interestingly, method allows one to produce semi-crystalline particles, while PEI known be hard crystallize typically in amorphous form. To get a deeper understandi...
