(A) Comparing functionalization of PET₂₀₁₈ and PET₂₀₀₉ (ozonation at 30 °C for various times from 10 to 60 min, grafting at 45 °C for 1 h) (n = 5). (B) Improving PNaSS GR of PET₂₀₀₉ fabrics by elevating PET grafting-from processing temperatures for 1 h at 25, 65, 70, 80, 100, 130 °C (n = 3) (ozonation 10 min at 30 °C); SFR used diethyl ether (DE).
