EDWARDS, Elilton Rodrigues; OISHI, Silvia Sizuka  e  BOTELHO, Edson Cocchieri. Analysis of chemical polymerization between functionalized MWCNT and poly(furfuryl alcohol) composite. Polímeros [online]. 2018, vol.28, n.1, pp.15-22.  Epub 15-Mar-2018. ISSN 1678-5169.  http://dx.doi.org/10.1590/0104-1428.07016.

In this study, the chemical interaction between functionalized carbon nanotuboes with carboxyl groups (CNT-f) and the subsequent addition of furfuryl alcohol (FA) and mixture with poly(furfuryl alcohol) (PFA) resin was evaluated. The FA with CNT-f was mixed in PFA resin to facilitate the chemical interaction of CNTs. The morphological and chemical interaction were studied by Transmission Electron Microcopies (MET), FTIR analyses, Raman Spectroscopy, viscosimetry and X-ray photoelectron spectroscopy (XPS). It was observed that a chemical interaction occurs through the opening of the hydroxyl polymer chain with a subsequent output of one water molecule. This interaction was evident from the FTIR and XPS data of the PFA composites. In this way, the mixture of functionalized carbon nanotubes with carboxyl groups in the FA, before adding this reinforcement into the PFA resin, can be considered a good procedure in order to obtain an appropriate chemical interaction between the CNT and PFA resin.
