Studies on Behaviour of Acid Functionalized Multi-Walled Carbon Nanotubes Partitioning in an Isoleucine Amino Acid and Dopamine Containing Poly(amide-imide) Based Blend Nanocomposites

In the passed decade, there have been extensive research activities on the development of carbon nanotube (CNT)/polymer nanocomposite (NC) materials with uniquecombinations of properties [1]. CNT/polymer NCs have shown promise in applications such as electromagnetic interference shielding, photovoltaic devices, gas sensors, thermal management, corrosion protection, and transparent conductive coatings [2]. Uniform distribution and dispersionof CNTs in polymer matrices is critical for realizing the full potential of NCs incorporating the CNTs; however, dispersionof CNTs remains a challenging problem [3]. Several methodshave already been developed over the last years to achieve an efficient dispersion of individual CNTs in a polymer matrix.One can modify the polymer in such a way that it can interact with the π-system of the CNT wall, or modify the walls of the CNTs by functionalization and so improve the wetting of the filler, as well as the dispersion in the medium [4].
