| Descripción: |
A detailed study about the synthesis, characterization and properties of poly(o-methylaniline)(PoMea)/maghnite nanocomposites
has been performed. Changes in the characteristics of the nanocomposites, depending on the intercalated cation
between the clay layers before the synthesis, have been observed. Intercalated morphology has been detected by TEM
in nanocomposites containing copper-treated maghnite (Magh-Cu), while when maghnite treated with strong acids was
used (Magh-H); an exfoliated material has been obtained. Also, remarkable differences in the properties of the polymers
have been observed by TG-MS and FTIR, suggesting that the polymer produced with Magh-H has a higher degree of
branching. The electrochemical behavior of the polymers extracted from the nanocomposites has been studied by cyclic
voltammetry. Good electrochemical response has been observed for PoMea grown into Magh-Cu but not for the one polymerized
into Magh-H. Ministerio de Educación y Ciencia (MAT2007- 60621 Project); Generalitat Valenciana (RED ARVIV2007/076); Algerian CNEPRU and FNR. |
