Polyarylates are wholly aromatic polyesters which have liquid crystallinity in a molten state. Due to liquid crystallinity, polyarylates have excellent mechanical properties, chemical resistance, and abrasion resistance. Because of these excellent properties, polyarylates are used in a variety of fields including automobiles, electric/electronic parts, technical fibers, molding compounds, etc. In this study, a series of composites based on PAR and MWCNT were fabricated by masterbatching and melt-compounding for applications requiring electrostatic dissipation, EMI shielding, and electric heating performance. For the purpose, the master chips with 10 wt% MWCNT were melt-compounded with neat PAR chips. The MWCNT content in the final PAR-based composites were controlled to be 0.2-10.0 wt%. The morphological features, thermal, mechanical, and electrical properties of PAR/MWCNT composites were characterized with aids of SEM, TEM, Rheometer, XRD, DSC, TGA, DMA, and electrometer, respectively |
