Carbyne and graphene are two materials that have gained significant attention in recent years due to their unique properties. Graphene, also known as single-walled carbon nanotubes (SWNTs), has been hailed as one of the most promising materials for a variety of applications due to its high electrical conductivity, mechanical strength, and thermal stability.

Carbyne, on the other hand, is a relatively new material that was first synthesized in 2016. It consists of a network of hydrocarbons within a periodically arranged layer structure. Unlike graphene, which is a bulk material, carbyne is typically used in thin films or as a composite material.
Despite their different origins, both carbyne and graphene exhibit remarkable properties that make them ideal candidates for various applications. For example, carbyne has been shown to have a high melting point, making it suitable for use as an insulator in electronic devices. It also exhibits excellent mechanical strength and can withstand extreme temperatures without losing its integrity.
In addition, carbyne has been found to be highly conductive, making it an attractive material for use in power electronics. This property makes it useful for creating efficient voltage regulators, switches, and energy storage systems.
On the other hand, graphene is known for its exceptional electrical conductivity, which can be increased by adding hydrogen molecules to the graphene sheet. This results in a material with a density of 3-4 times that of diamond, and it can carry significantly more current per unit area compared to graphene alone.
Graphene’s high electrical conductivity is due to the presence of large surface areas and strong electron-recombination centers. These features allow for the creation of a highly flexible and conductive material that can be used in a wide range of applications, from electronic devices to flexible electronics.
In terms of strength, carbyne has been shown to be stronger than graphene at room temperature. This is because carbyne has a higher concentration of functional groups, which allows it to accommodate larger molecules and thus provide greater strength. Additionally, carbyne’s relatively low melting point means that it can be formed into small and precise components, making it suitable for use in precision engineering.
Despite its high strength and electrical conductivity, carbyne has some limitations when compared to graphene. One of the main challenges in scaling up the production of carbyne-based materials is the need for a higher degree of control over the chemical composition and manufacturing process. This is because carbyne has a complex and delicate structure, and changes in the purity or composition can affect its performance.
Another challenge in scaling up carbyne-based materials is the need for stable synthesis methods. Graphene has been synthesized using a variety of reaction conditions, but achieving consistent and reproducible yields remains a challenge.

Overall, carbyne and graphene are two materials with unique properties that make them ideal candidates for various applications. While carbyne has been shown to have certain advantages over graphene in terms of strength and electrical conductivity, it still faces several challenges in scaling up its production and ensuring its stability. Graphene, on the other hand, continues to be the dominant material in the field of carbon nanomaterials, with potential applications in a wide range of industries.
