What is the cheapest graphene in the market?

As of my last update in October 2023, specific pricing for graphene products can vary widely based on several factors including the type of graphene (e.g., graphene oxide, reduced graphene oxide, or pure graphene), quality, form (powder, film, etc.), and the supplier. Prices for graphene can range from a few dollars per gram for lower quality materials to hundreds of dollars per gram for high-quality, single-layer graphene. To find the cheapest graphene in the market, I recommend checking recent quotes from various suppliers, including both small-scale producers and larger companies. Additionally, online marketplaces, research chemical suppliers, and materials suppliers often have competitive pricing. Remember to consider quality and intended application as lower prices sometimes indicate lower quality, which may not be suitable for all uses. If you're looking for specific suppliers or current pricing, it would be best to conduct an online search for graphene suppliers or check with distributors of materials for scientific research.
