Graphene is a type of carbon-based material that has gained significant attention due to its unique properties, including strength, flexibility, and high thermal conductivity. However, some experts have raised concerns about whether graphene can withstand outdoor exposure without failing.

One of the main concerns surrounding graphene is that it can lose its shape and functionality over time. This is because graphene is an amorphous material, which means that its structure is not fully defined and can change randomly as it is subjected to environmental factors such as temperature and humidity. As a result, if graphene is exposed to outdoor conditions for extended periods of time, it may lose its shape and become unable to function properly.
Another concern is that graphene can absorb a large amount of water and heat, which could lead to swelling or cracking of the material. This is particularly concerning if graphene is used in applications such as aerospace or automotive components where strong and durable materials are required.
Despite these concerns, some experts believe that graphene can still withstand outdoor exposure under certain conditions. For example, they argue that graphene can be coated with a protective layer to prevent it from absorbing moisture or heat. Additionally, some researchers have suggested that graphene can be grown on a substrate that is more resistant to outdoor conditions, such as concrete or metal.

Overall, while there are concerns about whether graphene can withstand outdoor exposure, it is important to note that many factors can influence the performance of a material, and it is always best to carefully evaluate the potential risks before using a particular material in a specific application. In addition, researchers continue to work on developing new methods for growing graphene on substrates that are more resistant to outdoor conditions, which could potentially make it easier to use this versatile material in various applications.
