Polyurethane-tetraaniline conducting composites: synthesis and their anti-corrosion performance
Abstract
Purpose
The purpose of this paper is to get the insulating polyurethane (PU) as conductive type polymer by compositing with oligoanilines, namely, tetraaniline (TANi) with an implication of its use as anti-corrosion coating material.
Design/methodology/approach
Water dispersion of PU was prepared and used as a host material for TANi for composite formulation.
Findings
The composites are very useful as anti-corrosion coating on mild steel as evident from Tafel polarisation studies.
Research limitations/implications
The solubility of TANi is limited in other organic solvents; because of this, a high-boiling solvent like N-methyl-2-pyrrolidone (NMP) is used.
Practical implications
It can be used as a good anti-corrosion coating on mild steel. Apart from anti-corrosion material, this can be used as conductive-based sensor material and also electrostatic dissipation (ESD) or electromagnetic interference (EMI) shield.
Originality/value
The work is original.
