Recent studies demonstrate that graphene and graphene oxide can be synthesized using inexpensive electrochemical exfoliation methods and modified household appliances, supporting the feasibility of home-based or low-cost laboratory production.
The retrieved papers include direct evidence of low-cost, simplified electrochemical and mechanochemical exfoliation techniques (such as using modified kitchen blenders or basic electrochemical cells) to produce graphene and graphene-related materials. Because these methods lower the barrier to entry and cost, they support the claim that synthesis can be achieved via home-based or accessible laboratory setups. No papers refute this claim.
