Self-healing conductive polymers

Definition

Self-healing conductive polymers are advanced materials that can autonomously repair themselves after being damaged while also conducting electricity. These polymers combine the properties of self-healing with electrical conductivity, allowing them to restore their functionality without external intervention. This unique characteristic makes them particularly useful in applications where durability and longevity are crucial, like in electronics and sensors.
