FAEZ, Roselena; MARTIN, Inácio M.; REZENDE, Mirabel C.  e  PAOLI, Marco-Aurélio De. Evaluation of a Conductive Elastomer Processing Using Scanning Electron Microscopy. Polímeros [online]. 2001, vol.11, n.3, pp.121-125. ISSN 1678-5169.  https://doi.org/10.1590/S0104-14282001000300011.

In this work the EPDM elastomer was mixed with Polyaniline (PAni) doped with dodecilbenzene sulfonic acid (DBSA) using a molar ratio of 1:3 of PAni:DBSA. The EPDM mixture with 40%(w/w) of PAni-(DBSA)3 was carried out using an internal mixer chamber with two rotors coupled to a Haake Rheocord 90 at 150°C and 30 rpm. Aliquots were taken during the processing time of 5, 10, 20, 30 and 40 min, and the morphology was evaluated by SEM. The morphology of the blends markedly changes as a function of processing time, from a compact, at 5 min to a sponge-like morphology at 30 and 40 min. These differences influence the material properties, such as electromagnetic radiation absorption of radar absorbing materials (RAM).

Palavras-chave : Conductive elastomer; polyaniline; EPDM; morphology; RAM.
