High‐Strength and High‐Toughness Double‐Cross‐Linked Cellulose Hydrogels: A New Strategy Using Sequential Chemical and Physical Cross‐Linking

Adv. Funct. Mater. 2016, 26, 6279 Figure 1 (a–c) were incorrectly assigned in the caption. The correct legend should read: “a–c) Photographs of the cellulose hydrogels: (a) physically cross-linked cellulose hydrogel, (b) DC cellulose hydrogel, and (c) chemically cross-linked cellulose hydrogel under bending.” A reflection peak was incorrectly assigned throughout the manuscript. All occurrences of (200) should be changed to (110). All reflections labeled initially (110) in the manuscript instead represent (110) In consequence two passages on page 6282 should read as follows: “…which correspond to the () and (110) reflections, respectively, of cellulose II crystallite.[26] Therefore, …resulted from the (110) reflection of the cellulose II crystallite hydrates…”. and “…the intensity of the peak at 20.2° for the (110) reflection of the cellulose II crystallite hydrates gradually increased,…” in addition text on page 6283 should appear as “Moreover, the intensity of the (110) reflection of the DC cellulose hydrogels increased as the concentration of aqueous ethanol increased…” and the corrected version of Figure 3 should appear as shown below: Figure 3. X-ray diffraction pro. les of the PC cellulose hydrogel, DC cellulose hydrogel, and CC cellulose hydrogel prepared using a) different ECH-to-AGU molar ratios and b) different concentrations of aqueous ethanol. The above errors do not affect the scientific conclusions drawn from the work. The authors apologize for any inconvenience or misunderstanding that these errors may have caused.
