Abstract—Graphene has taken the spotlight in the recent years in the scientific community; however, its industrial viability is yet to be fully realized. The present work aims to study the state of art of graphene production by analyzing patents deposited in Brazil which produce graphene via modified Hummers method. A brief review is made on modified Hummers method, where the reagents, mechanisms of the reaction, and process conditions are presented, as well as the characterization techniques commonly used in graphene-like materials. Graphite types, sizes and pre-treatment, reagents employed and possible substitutions, as well as graphene quality such as thickness, lateral size and O/C ratio are analyzed throughout the paper. Although all patents examined present detailed information and sought production in pilot or industrial scale, none presented the true scale produced in volume produced. Also, the possible environmental impact of gaseous emissions is emphasized in many patents and reagents substitutions are suggested to minimize or eliminate this problem in many of the patents analyzed. Despite all challenges presented in graphene production, recent publications have been showing great promised.
