A series of nanocomposites based on a new semi-crystalline polyimide (PI) and multi-walled carbon nanotubes (MWCNTs) were prepared by in situ polymerization. The TEM measurement reveals the improved dispersion of carboxylic acid-functionalized MWCNTs (COOH-MWCNTs) in semi-crystalline PI compared with pristine MWCNTs. The TGA analysis show that the concentration of carboxylic acid groups on the surface...
The nanocomposite films were synthesized based on the thermally stable benzoxazole-containing aromatic polyimide. The multi-walled carbon nanotubes in the concentrations from 0.25 to 1.0 wt.% were introduced in the matrix polymer as a nanofiller. Two types of nanotubes were used: the pristine nanotubes and those containing COOH-groups attached to the nanotubes’ surface. The impacts of the nanoparticles...
