4. Data Availability and Reproducibility Statement
All plotted numerical data (XRD, TGA, DSC, THz-IR, FTIR, 13C SSNMR, Gas permeation data, SEM EDS, XPS, and CO2 adsorption data) as shown in Figures 3 – 12, and Figures S1, S2, S4 and S6 can be found in the Supplementary Information. All data has been either calibrated, or corrected to calibration where required, according to widely practiced data analysis for specific techniques, such as carbon peak calibration for XPS data, XRD sample calibration, and background data removal for spectroscopic measurements. Where error bars are presented, repeat of the analysis measurements were made and the mean value was used, with the standard deviation reported as the error range/bar.
