Functionality

Definition

Functionality refers to the specific features or properties that a material possesses, which allow it to perform designated tasks or respond to external stimuli. In the context of smart and responsive polymers, functionality is crucial as it determines how these materials can react to changes in their environment, such as temperature, pH, or light. Enhanced functionality can lead to advanced applications in various fields, including medicine, environmental science, and engineering.
