“…Examples include ALD coating of synthetic polymers such as poly(ethylene terephthalate), polyethylene, or poly(vinyl alcohol), [4][5][6] polytetrafluroethylene 7 biopolymers such as celluloses, 8,9 spider silk, 10 etc. 12,13 Biopolymers usually comprise reactive groups that readily react with inorganic precursors, but for synthetic polymers or carbon, one might face the problem that there are no reactive groups that might covalently bind a monolayer of reactants at the initial deposition stage. 12,13 Biopolymers usually comprise reactive groups that readily react with inorganic precursors, but for synthetic polymers or carbon, one might face the problem that there are no reactive groups that might covalently bind a monolayer of reactants at the initial deposition stage.…”
