“…Polymers have increasingly stood out from other materials in the packaging industry when considering factors such as cost-effectiveness and design possibilities [1]. However, in the production of antistatic packaging for storage and transport of electronic components and devices, the insulating characteristic of the most polymers can result in electrostatic tensions accumulation, which, if not dissipated, can generate electrostatic discharge (ESD) capable of damaging and invalidating the product [1,2]. Many studies associate several polymers such as polyvinyl chloride (PVC) [3], low-density polyethylene (LDPE) [4], polyurethane (PU) [5], poly(lactic acid) (PLA) [6], polyamide 6/linear low-density polyethylene blends (PA6/LLDPE) [7], and aromatic polyesters such as poly(ethylene terephthalate) (PET) [8,9] and poly(trimethylene terephthalate)/acrylonitrile butadiene styrene blends (PTT/ABS) [10] as excellent candidates for the preparation of antistatic packaging.…”

Electronic devices require the use of antistatic packing to prevent electrostatic discharge during their storage or transport. Poly (trimethylene terephthalate) (PTT) is a polyester with excellent properties and can be a good candidate for this application. To make this insulating polymer an extrinsic conductor, carbon nanotubes (CNT) can be added to reduce the electrical resistivity of the nanocomposites. In order to facilitate the CNT distribution on polymeric matrix, it was proposed a chemical functionalization using nitric acid for the creation of functional groups on its surface. Moreover, the PTT matrix was modified with a compatibilizer agent based on maleic anhydride grafted PTT (PTT-g-MA), to improve interfacial adhesion between the nanofiller and matrix. In this work, nanocomposites based on PTT/PTT-g-MA/CNT were prepared by extrusion process, with 0.5 wt% and 1.0 wt% of CNT and functionalized CNT. CNT was characterized by stability dispersion in water, Raman spectroscopy, FTIR and XPS analysis, which prove the success of functionalization. The nanocomposites were evaluated by thermal analysis, tensile tests, electrical conductivity, and morphological analysis. The CNT functionalization and the addition of PTT-g-MA increased the dispersion and distribution of CNT in the PTT matrix. The electrical properties show that this material can be used as an antistatic packaging.
