Mechanical and optical properties of PTT/ABS/MWCNT nanocomposites for antistatic packaging

Antistatic packaging is extremely useful during the transport and storage of electronic equipment to avoid damages that can be caused by electrostatic discharge (ESD). In this work, it was prepared nanocomposites based on poly (trimethylene terephthalate) (PTT) and acrylonitrile butadiene styrene (ABS) blends as polymer matrix filled with multi-wall carbon nanotubes (MWCNT) as an antistatic agent. To improve the filler dispersion, it was conducted chemical functionalization of MWCNT using nitric acid. The MWCNT fillers were characterized by X-ray photoelectron spectroscopy (XPS) and transmission electronic microscopy (TEM). The PTT/ABS blend and the nanocomposites were characterized by optical and mechanical properties. Results showed that the MWCNT was successfully oxidized, and the nanocomposites presented excellent properties to be used as antistatic packaging. (author)
