PLAID PROVIDES UPDATE ON GRAPHENE DISPERSION TECHNOLOGY FOR CEMENT APPLICATIONS AND REPORTS ON INDUSTRY RESEARCH SUPPORTING GRAPHENE-ENHANCED MATERIALS

Plaid Technologies Inc. is providing an update on its continuing development work related to graphene-oxide dispersion methods for cement applications, including well bore cement. The company notes that a growing body of published research continues to explore the potential of graphene-enhanced materials in construction and industrial applications.

The company is also working with its contracted development partner Petro Flow LLC to incorporate an "ultrasonic injection process" designed to improve the dispersion of its graphene-oxide in cementitious mixtures. Preliminary internal laboratory-scale observations suggest that improved dispersion may influence hydration and cured material properties. Plaid continues to test and assess performance characteristics, scalability, and cost implications as part of its continuing development program.

Published peer-reviewed research has reported that small additions of graphene or its derivatives can influence the mechanical performance and durability of certain cementitious composites under laboratory conditions. The company's development program is designed to evaluate whether similar effects can be achieved consistently and economically using its dispersion approach in a broad range of targeted cement applications.

In the broader materials landscape, research on graphene-enhanced polymer composites (GRPCs) has shown how graphene can improve load-bearing capacity, flexibility and thermal properties in advanced polymer matrices -- findings that are driving interest in sectors such as aerospace, automotive and high performance manufacturing.

Broad industrial interest is being driven by several key performance advantages documented in the literature:

• Improved mechanical properties: Published studies have reported that graphene inclusion may enhance compressive, tensile and flexural strength in cementitious materials under laboratory conditions.
• Enhanced durability and reduced permeability: Research suggests graphene's surface area and interaction with matrix phases may improve microstructure and limit pathways for cracking and water ingress.
• Advanced composite performance: Graphene has been studied as a filler in polymer composites for potential improvements in mechanical integrity and resistance to degradation relative to traditional fillers.

By leveraging its proprietary formulation and dispersion techniques, Plaid is actively working towards converting well-documented graphene performance benefits into commercially viable, regulated and mission-critical use applications, beginning with well bore cement and expanding into additional high-value commercial construction applications.

Near term, Plaid is focused upon commercial applications in well bore cement and construction materials, where dispersion quality is a key technical factor affecting repeatable performance. The company believes that improved dispersion methods, once further validated, will support performance optimization and potential cost efficiencies.

With nearly 4.5 million orphaned and abandoned wells in the United States alone, and given the detrimental effect many of these methane-leaking wells have on the environment, Plaid acknowledges the urgency in developing more expedient, durable and cost-effective methods to plugging. Through the Bipartisan Infrastructure Law (BIL) the United States federal government alone has committed $4.7-billion for an initial phase to begin addressing the problem. At this stage, Plaid has not received any contracts under the BIL plan.

"Published research continues to highlight graphene's potential to enhance conventional industrial materials," said Guy Bourgeous, chief executive officer of Plaid Technologies. "Our focus is on advancing dispersion methods that could enable practical, scalable use of graphene in cement applications, including well bore cement. We believe this work positions Plaid to address real-world performance and deployment challenges, and we look forward to reporting further progress as our development program advances."
