Degrafting reaction of polymer brushes: the determining role of molecular weight and grafting density

Key Points

• The research aims to understand how molecular weight and grafting density influence the stability of polymer brushes in various environments.
• Analyzed the chemical stability of polymer brushes under different conditions.
• Varying molecular weights and grafting densities were tested.
• Used water exposure to simulate real-world applications.
• Higher molecular weight showed increased stability for polymer brushes.
• Increased grafting density correlated with reduced detachment rates.
• Identified specific thresholds where stability dramatically changes.
