And Storage

Antistatic packagings are very important for proper transportation and storage of electronic components since these components can be damaged with electric overloads generated through rubbing. Therefore, the purpose of this study was to develop an innovative material for antistatic packaging with a sustainable character. For this, a blend of recycled poly(ethylene terephthalate) (PET), polycarbonate (PC), and polyaniline (PAni) was prepared by melt extrusion. Samples have a final content of 68 wt% of PET, 29 wt% of PC, and 3 wt% of PAni doped with cobalt (PAni-Co). The properties were determined by differential scanning calorimetry, thermogravimetric analysis, tensile testing, electrical resistivity analysis, and Fourier transform infrared spectroscopy. To the best of our knowledge, no previous work studied the incorporation of PAni-Co in PET/PC blend.

A nanocomposite catalyst was prepared from immobilization of aluminum oxide hydroxide onto the attapulgite for synthesis of Poly (ethylene terephthalate) (PET). Differential scanning calorimetry (DSC) analysis was used to investigate the crystallization properties of PET obtained by using the different catalysts, and the results showed that PET obtained by using the as-prepared catalyst exhibited higher crystallization crystallizability under applied conditions.
