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.
Abstract
The chemical stability of polymer brushes is mandatory to ensure their applicability in a wide range of environments. However, it is well-known that, in presence of water, polymer chains detach...
