石墨烯在日常设备中的隐形作用

Graphene is a single layer of carbon atoms arranged in a honeycomb lattice structure.
It conducts electricity better than copper and transfers heat more efficiently than any known material.
Though invisible to the naked eye, tiny amounts improve battery life in smartphones and laptops.
Researchers add graphene to touchscreens to make them thinner, stronger, and more responsive.
Some sports helmets now integrate graphene composites for lighter weight and greater impact resistance.
Its flexibility allows embedding into wearable sensors that monitor heart rate or muscle activity.
Manufacturers still face challenges scaling production, but pilot uses appear in headphones and smartwatches.
Unlike plastics or metals, graphene degrades slowly—raising questions about long-term environmental impact.
