In our study, we conducted oxygen permeability assessments on three types of polymer films: POF-DLF, PDF-DLF, and PDDF-DLF. Unfortunately, we were unable to measure the OTR of the polymer film obtained from the PHF-DLF copolyester due to its brittleness. Table displays the OTR values of the films, revealing an increasing trend as the number of carbon atoms within α,ω-ALD increased.
