Original Articles Recovery of the post-industrial recycled ABS thermomechanical properties by adding graphene oxide Lima, Lucas Pacanaro de Petraconi, André Braga, Natália Ferreira Costa, Lidiane Cristina Andrade, Ricardo Jorge Espanhol Fechine, Guilhermino José Macêdo Abstract in English: Abstract The post-industrial recycled ABS (ABSpost) was used to produce a new material based on graphene oxide (GO), aimed at high-quality products again, as households and electronic applications. The GO was prepared from the oxidation of graphite, and the influence of the different amounts of filler on the mechanical, rheological, and thermal properties of ABSpost was investigated. The X-ray microtomography showed a uniform dispersion of GO fillers in the ABSpost matrix in small amounts (0.05 and 0.1 wt%), improving some properties, such as elongation at break, toughness, and impact strength. The thermal conductivity of the ABSpost also increases by 30% with the addition of only 0.1 wt% of GO. Adding a small amount of GO in a recycled ABS is a strategy to deal with the current problem of electronic housing waste and use this material to minimize its environmental impact. |
