Polymer conductors are materials made from long chains of molecules, known as polymers, that can conduct electricity. Unlike traditional metals, these materials can be flexible and lightweight, making them suitable for various applications, such as in electronics and sensors. They are often used in devices like organic light-emitting diodes (OLEDs) and solar cells. These conductors work by allowing electrons to move through the polymer chains, which can be enhanced by adding certain chemicals or dopants. Research in this field aims to improve their conductivity and stability, potentially leading to new technologies in areas like wearable electronics and flexible displays.
