The synthesis and properties of isocyanate-based polyimide foam composites containing MWCNTs of various contents and diameters

PIFs were synthesized using in situ polymerization from PAPI, PMDA, and MWCNTs (0.05, 0.1, 0.2, 0.4, and 0.6 wt%) functionalized with –OH; the diameters were 10–20 nm, 20–30 nm, and >50 nm.
