Calgary, Alberta--(Newsfile Corp. - October 2, 2025) - Volt Carbon Technologies Inc. (TSXV: VCT) (OTCQB: TORVF) ("Volt Carbon" or the "Company"), is pleased to announce significant updates relating to its intellectual property, graphene development program, and stock option grants.
Notice of Allowance for Second U.S. Patent
The United States Patent and Trademark Office ("USPTO") has issued a Notice of Allowance for U.S. Patent Application No. 18/782,462. This application is a continuation of the Company's previously issued U.S. Patent No. 12,172,192, in which additional aspects of the inventions were pursued in a continuation application to secure broader protection of the Company's proprietary air classifier technology. A Notice of Allowance means that the patent examiner has reviewed the patent application and determined it meets the requirements for patentability.
To complete the process, Volt Carbon must pay the required issue fee, after which the USPTO will assign a U.S. patent number and issue date. The Company views this continuation as expanding the scope of its air classifier protection for graphite processing and advanced material applications.
Graphene Oxide Production and Strength Testing
Volt Carbon has successfully produced reduced graphene oxide (rGO) from Berkwood flake graphite that was previously processed using the Company's proprietary air classifier and stored at its Guelph plant. That material was used to produce five-layer rGO sheets measuring up to ~16.5 microns wide, as confirmed through Transmission Electron Microscopy (TEM) imaging (Figure 1). The Chemical Engineering Department at the University of Waterloo independently verified the sheets as five-layer rGO, which were then incorporated into an epoxy matrix, the standard resin in aerospace carbon fiber composites, and fabricated into test coupons. Mechanical testing demonstrated a 40-60% improvement in mechanical properties compared to virgin epoxy. This strong performance is attributed to the large sheet dimensions of the five-layer rGO and is considered at the high end of improvements reported in scientific literature for graphene-reinforced epoxy systems.
These results highlight the potential for Volt Carbon's rGO to reinforce epoxy resins used in carbon fiber composites, addressing a key limitation of aerospace CFRPs such as brittleness and interlaminar cracking. By strengthening the matrix phase, Volt Carbon's material could enable lighter, tougher composite structures that extend aircraft range, improve fuel efficiency, and support next-generation aerospace design. These findings also position Volt Carbon to pursue partnerships in aerospace composites and advanced materials markets.
