ReviewPolyaniline thermoset blends and composites

The blending of polyaniline (PANI) with insulating polymers is an active area of research which has been driven by the possibility to combine the good mechanical properties and processability of the polymer matrix with low electrical resistance. This review will focus on thermosetting polymer matrix composites or blends. A good dispersion of PANI in the thermoset matrix is essential for the enhanced mechanical and electrical properties of the material. Much effort has been exerted in attempts to improve the compatibility of PANI with thermoset matrices. Attention will be given to describe some of the processing parameters that affect the morphology of PANI thermoset blends and composites. In recent years, there has been renewed interest in PANI thermoset composites with the emergence of multifunctional ternary composites. The different approaches for the design of ternary composites will be reviewed. Additionally, promising applications of PANI thermoset composites in different fields will be described such as electromagnetic shielding and microwave absorption, static electricity dissipation, flame-retardant materials, conductive adhesives, coatings for anticorrosion protection, sensor materials and electro-stimulated drug delivery systems.
