Figure 7.

Thermogravimetric analysis (TGA) curves (A) and derivative thermogravimetric (DTG) curves (B) of textile and textile covered by chitosan and chitosan-polydopamine, measured under nitrogen. Black line: textile without adhesive; blue line: textile covered by chitosan and red line: textile covered by chitosan-polydopamine adhesive. (C) The textile and cardboard samples without adhesive are reported on the left (top and bottom, respectively). The samples covered by the adhesive are reported on the right (top and bottom, respectively). The black color of the adhesive is due to the presence of polydopamine.
