Polyimide

A new class of multi-wall carbon nanotubes (MWCNTs)/carbon nanocomposite thin films was successfully prepared by incorporating (MWCNTs) into polyimide (PI) precursor solution. The carbon films were obtained in only one coating step by spin-coating technique on a macroporous alumina substrate and wer

A series of polyimide/vanadium pentoxide (PI/V2O5) hybrid film has been successfully fabricated through the in situ formation of V2O5 within a polymer matrix by sol–gel process. The polyamic acid (PAA) is prepared from 4,40 -diaminodiphenyl ether (ODA) and 3,30 ,4,40 -benzophenonetetracarboxylic anh

In this paper, nanocomposite materials based on TiO2 and polyimide derived from HQDPA and DMMDA were prepared by blending of TiO2 sol and polyimide solution. Because of the improvement of the TiO2 sol preparation process and blending methods, the TiO2 content of the obtained TiO2/polyimide composite

Well-equilibrated molecular packing models have been produced for seven different polyimides. For all packings the transport properties (solubility and diffusion coefficient) have been calculated for nitrogen, oxygen and carbon dioxide using the Gusev-Suter method. Comparison with experimental data
