Explanation:

• Graphene is a one-atom-thick layer of carbon atoms arranged in a hexagonal lattice.As the building block of graphite, graphene possesses remarkable characteristics that make it a potential game-changer in various industries.
• Graphene’s capability to absorb and dissipate electromagnetic waves positions it as a valuable component for stealth coatings and materials that reduce radar signatures and electromagnetic interference.Hence statement 1 is correct.
• Its properties: It surpasses copper in electrical conductivity, being 200 times stronger than steel yet six times lighter.
• With exceptional transparency of absorbing only 2% of light, it also exhibits impermeability to gases, including hydrogen and helium.
• The high surface-area-to-volume ratio of graphene, stemming from its thinness, makes it a promising candidate for energy storage.
• Graphene's sensitivity to environmental changes makes it an excellent candidate for • sensing chemical and biological agents, explosives, radiation, and other hazardous substances.
• It also holds promise in numerous applications such as efficient and precise sensors, faster and more efficient electronics, efficient solar panels, accelerated DNA sequencing, and drug delivery systems.Hence statement 2 is correct.
• It has been proven that even a minuscule amount of graphene added to plastics, metals, or other materials can significantly enhance their strength.
• These graphene composites find applications in aerospace, automotive, sports equipment, construction, high-performance batteries, conductive inks, water purification, desalination, and even in the production of graphene-based masks during the COVID-19 pandemic.Hence statement 3 is correct.
