The polyarylate with the new composition fabricated a nanocomposite with pristine MWCNT. It has been confirmed that the nanocomposite prepared through the master batch melt compounding has excellent physical properties without deteriorating the original properties of the polyarylate. Especially, high thermal properties has been obesrved that the melting temperature is higher than 330 °C and the maximum decomposition temperature is higher than 500 °C. In addition, because of the effect of MWCNT, the storage elastic modulus and retentiveness against temperature was improved and the electric conductivity was also found to be 0.42 S/cm at 10 wt%. Such improvement in properties suggests that nanocomposites should be applied in fields requiring electrostatic dissipation, EMI shielding, and electric heating performance. In this study, a series of nanocomposites based on PAR and MWCNT were fabricated by masterbatching and melt-compounding for electrical heating application and were characterized with various method. |
