Studying Some Electrical and Mechanical Properties of Epoxy- Polyaniline (PANI) Composites

Abstract

As ordinary known the ability of synthesizing electrical conducting polymercomposite is possible but with poor mechanical properties, for the solution of thisproblem, we carried out this study in order to obtain both properties.The PANI composite was prepared by using the prepared (EP/glass fiber)composite as substrate for the deposition of the PANI. The chemical oxidativemethod was adopted for polymerization of the aniline and simultaneouslyprotonated of PANI with a hydrochloric acid at a concentration of (1M).Theoxidation agent (FeCl3.6H2O) was used. The conductivity results showed that theprepared composite lies within semiconductors region (1.7×10-3(S.cm-1)). TheHall Effect measurement showed a p-type behavior for the prepared composite.The creep and tensile behavior was studied and concluded that PANI Precipatedon the EP/glass fiber composite has no remarkable effect on the mechanical creepand tensile behavior as compared with the untreated composites with PANI.Buthave higher creep resistance and ultimate strength.
