Poly(amide-imide) Nanostructures Containing Dopamine and Natural Amino Acids for High Performance Materials: Synthesis under Safe and Green Conditions

Poly(amide-imide)s (PAI)s with amide and imide linkage in the main chain are certainly one of the most successful classes of high-performance polymers with outstanding mechanicaland thermal properties at high temperature with good dimensional stability, excellent creep, impact and chemicalresistance as well as solvent resistance [1,2]. A wide range of PAIs have been investigated as high performance materials for applications, such as moldings, wire-coating enamels, hightemperature adhesives, and liquid crystal alignment [3]. Numerous studies have reported on the application ofionic liquids (ILs) in different fields of chemistry as well as polymer chemistry. Recently, new applications for moltentetrabutylammonium bromide (TBAB) as a reaction medium for step-growth polymerization have also been presented [4].
