Fiber with Butterfly Wings: Creating Colored Carbon Fibers with Increased Strength, Adhesion, and Reversible Malleability

Colored and color-changing materials are central to perception and interaction in nature and have been used in an array of modern technologies such as sensors, displays, and smart materials.

Eyckens and coworkers presented carbon fibers incorporating structural color, similar to that observed on the surface of soap bubbles and various insects and birds, by modifying the fiber surface through in situ polymerization grafting. This approach creates a new platform for the multifaceted advance of smart composites.
