Description
We prepared carbon nanotubes (CNT)-polyimide composites with 0 and 1 wt% single wall-, double wall- CNTs using BPADA, BAPP, and refluxing in NMP. The FT-IR spectra for all the samples showed the characteristic peaks of polyimide. TGA curves showed the residual weight at 750°C of ~ 40% for pure/functionalized-CNT polyimide composites, and ~ 80% for non-functionalizes-CNT polyimide composites. DSC curves of all samples showed two distinguishable endothermic peaks at around 90°C and 200°C. Positron lifetime has a correlation with tensile strength showing a decrease in tensile strength with increasing pore size in CNT-polyimide composites.
