Correction: Zhu et al. Electroactive Oxidized Alginate/Gelatin/MXene (Ti₃C₂Tx) Composite Hydrogel with Improved Biocompatibility and Self-Healing Property. Polymers 2022, 14, 3908

In the original publication [1], there were mistakes in Figure 3d and the relevant description as published. There was an error regarding the y-coordinate of Figure 3d, meaning that the value of conductivity was wrong. The corrected Figure 3 and the relevant description appear below.

Figure 3. (a) Variations of viscosities with increasing shear rate and (b) variations of storage and loss moduli with shear stress of different hydrogels. (c) The Nyquist plot and (d) conductivity of different hydrogels. (e) The self-healing and the ability of MXene-ADA-GEL with a light lamp.

In Section 3.2, paragraph 2: “…and the conductivity increased from 2.99 ± 0.63 S m⁻¹ to 3.66 ± 0.55 S m⁻¹ when 2 w/v% of MXenes were added into the ADA-GEL” should be changed to “…and the conductivity increased from 0.299 ± 0.063 S m⁻¹ to 0.366 ± 0.055 S m⁻¹ when 2 w/v% of MXenes were added into the ADA-GEL”.

The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
