Fabrication of Anti-Static Carbon Nanotube Film on Polyethylene Naphthalate

摘要

The primary goal of this study was to develop thermally stable, transparent and anti-static films on a flexible polymeric substrate using multi-wall carbon nanotubes (MWCNTs). For this, Polyethylene naphthalate (PEN) was selected as a thermally stable substrate and Poly-methylmethacrylate (PMMA) as a binder between the MWCNTs and PEN substrate. 5 wt% of polymer dispersion agent (PDA) was used to improve the dispersion stability of 1 wt% of MWCNTs in Isopropyl alcohol (IPA). The coating of MWCNT/PMMA was uniformly fabricated on PEN using a bar coater and the prepared films were investigated for their morphology, thermal and opto-electrical properties with applied heat treatment. The MWCNT/PEN films showed superior result according to adhesion test scale (ISO class 0) with excellent heat stability performance at 200°C for 1 h. Furthermore, electrical property of this transparent film was improved through heat treatment. These achieved results highlight the potentiality of this low cost, anti-static CNT films as an attractive material to use in numerous flexible electronic devices.
