Morphological, electrical, thermal and mechanical properties of phthalocyanine/multi-wall carbon nanotubes nanocomposites prepared by masterbatch dilution

Multi-wall carbon nanotubes reinforced thermoset phthalocyanine (Pc/CNTs) nanocomposites were successfully prepared through melt-mixing and masterbatch dilution and investigated for their morphologies and physical properties. Pc/CNTs nanocomposites were prepared by the more optimized masterbatch method. The feasibility of using Pc/CNTs nanocomposites was investigated by evaluating their electrical, dielectric, mechanical, morphological and thermal properties as a function of CNT loading. Consequently, the dramatic electrical and dielectric transition happened when CNT content was about 1 wt%. For the 1 wt% CNTs-filled Pc nanocomposites, a 51.4 % increase in flexural strength was obtained and flexural modulus was also improved from 3851.7 MPa to 3973.3 MPa. All Pc/CNTs nanocomposites showed high thermal and thermo-oxidative stabilities up to 535 °C. Pc/CNTs nanocomposites with multifunctional properties can find uses under some critical circumstances with requirements of high strength and temperature.
