Effect of the Nature of Metal Ions and the Type of Solvent on the Mechanical, Self-Healing and Conductive Properties of Poly(AA-Co-AAm) Gels

Composite hydrogel based on acrylic acid and acrylamide, modified with metal ions (Ni2+, Al3+, Fe2+, Fe3+) with concentration 0.3 wt%, were synthesized in water or polyethylene glycol (with a molecular weight of 400 Da) at three monomer ratios (7/3, 1/1, 3/7). Dynamic mechanical analysis shows that the equilibrium modulus of elasticity (<!-- MathType@Translator@5@5@MathML2 (no namespace).tdl@MathML 2.0 (no namespace)@ -->
