Ti3C2Tx (MXene)–polyacrylamide nanocomposite films†
Herein we report on the synthesis and characterization of MXene–polyacrylamide (PAM) nanocomposite films. Dimethylsulfoxide intercalation in-between the Ti3C2-based MXene layers led to full delamination of the MXene layers and hence a uniform dispersion of hydrophilic MXene nanosheets in aqueous PAM solutions was achieved. Polymer composite solutions of up to 75 wt% were synthesised. The as-prepared composite samples are flexible and the conductivity was increased significantly to 3.3 × 10−2 S m−1 with only 6 wt% (1.7 vol%) MXene loading.
