Which outcome occurs when a fluoropolymer coating is exposed to highly concentrated alkali hydroxide?

💡 Explanation

When a fluoropolymer is exposed to concentrated hydroxide, defluorination occurs because the highly electronegative fluorine atoms are susceptible to nucleophilic attack by the hydroxide ions, breaking the C-F bonds. Therefore, defluorination occurs, rather than crosslinking, crystallization, or embrittlement which result from different degradation mechanisms.
