Correction to “Photoreversible Bond-Based Shape Memory Polyurethanes with Light-Induced Self-Healing, Recyclability, and 3D Fluorescence Encryption”

T here are some errors in the original version of our article.First, on page 33830, the chemical structure of 2bromoethanol in Figure 1 (Step 2) was mistakenly drawn as 3-bromopropanol.Correspondingly, the chemical structures of HEOMC (Figure 1, Step 2, and Figure S1) and HEOMC-PU (Figure S3) need corrected.Moreover, this error resulted in incorrect characterization of the signal peak at 3.34 ppm in 1 H NMR spectra (Figures S1 andS3).Thus, the signal peak at 3.34 ppm should be corrected to the signal peak of H 2 O, and the sequence number of the signal peaks in 1 H NMR spectra (Figures S1 andS3) has also been adjusted.These corrections do not affect the conclusions of the material synthesis and characterization results of this article.The corrected Figure 1 is shown here.The corrected Supporting Information, with corrected Figures S1 andS3, is included here.Second, on page 33831, the masses of PCL-diol and HEOMC in the "Synthesis of the HEOMC-PU Network" section are incorrect due to data entry errors.These errors caused the mass fractions of PCL, IPDI, BDO, and HEOMC and hard segment content in Table S1 and hard segment content in the original article to be incorrect.Therefore, the mass of PCL-diol should be corrected from "20 g" to "30 g", and the mass of HEOMC should be corrected from "0.1 g" to "1.1 g".Also, the mass fractions of PCL, IPDI, BDO, and HEOMC and hard segment content in Table S1 were recalculated and corrected.After correcting the errors in Table S1, the mass fraction of PCL increased by 3.6%-10.3%,IPDI decreased by 3.2%-9.4%,BDO decreased by 0.2%-1.9%,HEOMC changed by 0.1%-0.4%,and the hard segment content decreased by 3.6%-10.3%.Although these errors have been corrected, the molar ratios of all raw materials were not changed by these errors.Meanwhile, the authors emphasize that the corrected contents do not affect the discussion or conclusions drawn in the original article, including exceptional mechanical performance, efficient self-healing performance, and multiple ways of reprocessing of HEOMC-PU.The corrected Supporting Information, with corrected Table S1 and eq S1, is included here.Third, there are errors in the calculations of the self-healing efficiencies of HEOMC-PU-3, HEOMC-PU-4, and HEOMC-PU-5 in Table S6.The value of "99.1%" should be corrected to "99.2%", the value of "71.2%" should be corrected to "76.8%", and the value of "71.1%" should be corrected to "70.7%".The authors emphasize that the corrected values do not affect the conclusions of the efficient self-healing performance.The corrected Supporting Information, with corrected Table S6, is included here.
