Describe how self-healing polymers could be useful in the construction of
plastic frames for glasses and sunglasses.

Sagot :

Answer:

This can be achieved through the use of a built-in fiber-optic network of cables that deliver light and heat energy to the point of breakage.

Explanation:

Self-healing polymers are materials designed to aid the internal healing of materials like plastics, and metals. Shape-memory materials used in the making of plastic frames for glasses and sunglasses allow these materials to snap back into shape when they crack.

This is possible because heat is needed to help a deformed material regain its shape. Built-in fiber-optic network of cables serve the purpose of delivering heat to the deformed or cracked area, thus helping them to regain their shape.
