MXene-based polymer nanocomposites have recently been investigated for enhancement of mechanical properties(e.g. elastic modulus, tensile strength) and thermal properties(e.g. thermal conductivity, stability). In order to fabricate polymer nanocomposite with MXene, good dispersion should be considered through modification. Here, we report PA6 nanocomposites filled with modified MXene for enhancement of mechanical and thermal properties. MAX(Ti3AlC2) was first etched with hydrochloric acid and lithium fluoride to exfoliate MXene nanosheets. As modifier, Jeffamine D-400 was adsorbed on the surface of MXene by ion exchange reaction with Li+ ion. Modified MXene was then melt mixed with PA6 and compression molded. Mechanical, and thermal properties were investigated on different loadings of modified MXene. The modified MXene was well dispersed as exfoliated state, which made the nanocomposites have high mechanical properties and thermal stability. |
