AB  - To develop antistatic materials suitable for semiconductor wafer transportation trays, in situ polymerized polystyrene (PS) and polyester (PETE) materials incorporating multi-walled carbon nanotubes (MWNTs) were synthesized. Their thermal and electrical properties were evaluated under conditions relevant to semiconductor tray manufacturing. Both the PS and PETE materials exhibited improved thermal stability with an increasing MWNT content. Differential scanning calorimetry (DSC) revealed that the glass transition temperature (Tg) of the PS increased from 82 °C (0 wt%) to 86 °C (1.0 wt%) and 91 °C (2.0 wt%), while that of the PETE increased from 83 °C to 84 °C and 90 °C, respectively. Surface resistivity measurements also demonstrated enhanced electrical conductivity. For the PS, resistivity decreased from >1013 Ohm/sq to 8.8 × 103 and 3.7 × 103 Ohm/sq at 1.0 wt% and 2.0 wt% MWNT, respectively. The PETE materials followed a similar trend, with values dropping from >1013 Ohm/sq to 5.9 × 103 and 0.2 × 103 Ohm/sq. These results confirm that MWNT incorporation effectively enhances both thermal and electrical performance, demonstrating the potential of MWNT/PS and MWNT/PETE as antistatic materials for semiconductor applications.
