In the published article, there was an error in Figures 11, 12. The order of magnitude was incorrect in Figures 11A, D and Figures 12A, D. The correct figures and their captions appear below.
In the published article, there was an error in Supplementary Figure S20, which had incorrect dimensions. The correct figure and its caption appear below.
FIGURE 11
FIGURE 11. The ion content dependence of (A) Young’s modulus, (B) stress at break, (C) strain at break, and (D) fracture energy (WB) of C4ASA-films with 1% (blue), 2% (black), and 5% (red) BudMA. The fracture energies were defined as the integrals of stress-strain curves.
FIGURE 12
FIGURE 12. The ion content dependence of (A) the Young’s modulus, (B) the stress at break, (C) the strain at break, and (D) the fracture energy (WB) of films with 2% BudMA and varying concentrations of C4ASA (black) or C6ASA (red). The fracture energies were defined as the integrals of stress-strain curves.
SUPPLEMENTARY FIGURE S20
SUPPLEMENTARY FIGURE S20. The Young’s moduli (A), stresses at break (B), strains at break (C), and fracture energies (D) of films with 5% of C4ASA, C6ASA, or PC6ASA. Each film contains 2% BudMA.
The authors apologize for these errors and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
