Structural, physical, wear and anticorrosive properties of electroactive polyamide/Ti3C2Tx MXene nanocomposite

Abstract

The 2D few-layered Ti3C2Tx MXene nanosheets have been prepared by etching and delamination of aluminium layers from the Ti3AlC2 MAX phase. The electroactive polyamide (EPA)/Ti3C2Tx MXene nanocomposites (NCs) containing (0.6, 1.2 and 1.8 wt%) MXene were prepared via in-situ oxidative coupling polymerization. The structural properties of NCs indicated close interaction between EPA and MXene resulting in improvement in physical properties such as electrical conductivity, thermal stability and adhesion strength. The surface roughness and water contact angle were not affected by the addition of Ti3C2Tx MXene in the EPA matrix. The tribological properties were improved for NCs coated samples. The corrosion study revealed the excellent corrosion protection ability of EPA/Ti3C2Tx MXene NCs containing 1.2 wt% MXene.
