dc.description.abstractPolyimide (PI)-based nanocomposites containing aminophenyl functionalized multi-walled carbon nanotubes (AP-MWCNTs) obtained through a diazonium salt reaction was successfully prepared by in situ polymerization. PI composites with different loadings of AP-MWCNTs were fabricated by the thermal conversion of polyamic acid (PAA)/ AP-MWCNTs. The mechanical and electrical properties of the AP-MWCNTs/PI composites were improved compared with those of pure PI due to the homogeneous dispersion of AP-MWCNTs and the strong interfacial covalent bonds between APMWNT and the PI matrix. The conductivity of APMWNT/PI composites (5:95 w/w) was 9.32×10-1 S/cm which was about 1015 times higher than that of Pure PI.The tensile strength and tensile modules of the AP-MWCNTs/PI composites with 0.5wt% of AP-MWCNTs were increased by about 77% (316.9 ± 10.5 MPa) and 25% (8.30 ± 1.10 GPa) compared to those of pure PI, respectively.-
