Dichloromethane (DCM, 99.9%, Molar Chemicals, Halásztelek, Hungary), tetrahydrofuran (THF, 99.9%, VWR Chemicals, West Chester, PA, USA), benzotrifluoride (BTF, ≥99%, Sigma-Aldrich, St. Louis, MO, USA) and 2-ethyl-2-oxazoline (EtOx, 99+%, Aldrich, St. Louis, MO, USA) were refluxed on CaH₂ for a couple of hours and distilled over it under N₂ atmosphere freshly before use. Triethylamine (TEA, ≥99.0%, TCI Chemicals, Tokyo, Japan) and 1-methylimidazole (1-MI, ≥99%, Sigma-Aldrich, St. Louis, MO, USA) was distilled under N₂ atmosphere freshly before use. Glissopal 1000 (BASF SE, Ludwigshafen, Germany), p-toluenesulfonyl chloride (tosyl chloride, TsCl, ≥99.0%, TCI Chemicals, Tokyo, Japan), p-nitrobenzenesulfonyl chloride (nosyl chloride, NsCl, 97%, Sigma-Aldrich, St. Louis, MO, USA) and 4-dimethylaminopyridine (DMAP, ≥99.9%, Sigma-Aldrich, St. Louis, MO, USA) were used as receive.

For the EAO synthesis, IA (99%, Junsei Chemical, Tokyo, Japan) and bisphenol A diglycidyl ether (BADGE; Sigma Aldrich, St. Louis, MO, USA) were used as monomers, Benzyltriethylammonium chloride (BTEAC; 99%, Sigma Aldrich, USA) was used as a catalyst, 1-propanol (99%, Samchun Chemicals, Seoul, Republic of Korea) was used as a solvent, and hydroquinone (≥99%, Sigma Aldrich, St. Louis, MO, USA) was used as an inhibitor. Acrylic acid (AA; 99%, Sigma Aldrich, St. Louis, MO, USA) and trimethylolpropane triacrylate (TMPTA; Sigma Aldrich, St. Louis, MO, USA) were used as a co-monomer and crosslinker, respectively, without purification. For comparison with the synthesized EA oligomer, bisphenol A glycerolate diacrylate (BA; Sigma Aldrich, St. Louis, MO, USA) and bisphenol A glycerolate dimethacrylate (BMA; Sigma Aldrich, St. Louis, MO, USA) were used. The photoinitiator 2,2-dimethoxy-2-phenylacetophenone (DMPA; Sigma Aldrich, St. Louis, MO, USA) and the thermal curing agent 1-methylimidazole (1-MI; ≥99%, Sigma Aldrich, St. Louis, MO, USA) were used without purification. The polycarbonate (PC) film (1T, Hwa-in Science, Seoul, Republic of Korea) was used as purchased.

Raw cotton fabric (plain weaved, 30 Ne, 126.3 g/m²) was purchased from a local fabric store. Tetraethyl orthosilicate (TEOS, 98%), isopropyl alcohol (IPA, 99.5%), 3-glycidoxypropyltrimethoxysilane (GLYMO, 98%), 1-methyl imidazole (1-MI, 99%) and ammonium hydroxide solution (NH₄OH, 28%) were purchased from Sigma-Aldrich (St. Louis, MO, USA) and used without further purification. Fluorolink S10, n-dodecane, and ethanol were purchased from Solvay, Kanto Chemical (Tokyo, Japan), and Samchun Chemical (Seoul, Korea), respectively.
HD (2, 2′-dichloroethyl surfide), GD (3, 3-dimethyl-2-butyl methylphosphonofluoridate), and VX (O-ethyl-S-2(diisopropyl amino)ethyl methylphosphonothioate) (≥99%) were provided by the Chemical Analysis Test and Research Laboratory at the Agency for Defense Development (ADD, Daejeon, Korea). Due to their extreme danger and toxicity, extreme care was taken when handling CWAs. CWAs should only be handled by trained personnel using sufficient protective equipment and relevant safety procedures, as was done in this study.
