Fig. 4. (a) The proposed mechanism of polymerization initiated by p-Ti3C2Tx or ammonium persulfate. (b) Acid stability of three p-Ti3C2Tx-containing dispersions. Sample 1: pristine p-Ti3C2Tx; Sample 2: physical mixture of PNIPAM and p-Ti3C2Tx; Sample 3: PNIPAM-based NC polymer. The TEM image of p-Ti3C2Tx (c) and the PNIPAM-based NC polymer (d).
