Global Graphene, 2D Materials and Carbon Nanotubes Markets Forecast 2019-2030
May 28, 2019 | Business WireEstimated reading time: 3 minutes
This report offers a comprehensive analysis of the current and future markets for graphene, non-graphene 2D materials and carbon nanotubes (multi-walled carbon nanotubes, single-walled carbon nanotubes, few-walled carbon nanotubes, double-walled carbon nanotubes, etc.)
Graphene
There are now over 250 companies either producing graphene or developing applications, with scores of multi-nationals conducting R&D on these materials. Several start-ups developing graphene applications have recently received multi-million-dollar funding and graphite producers are announcing plans to start multi-ton production.
The current global production capability for graphene is inflated by the production of graphene slurries and powders, mainly in the Taiwan and China markets. The market is in an oversupply situation, but a lot of what is available is thin graphite, especially in these markets. According to research by the Centre for Advanced 2D Materials (CA2DM) at the National University of Singapore (NUS), many graphene producers supply thin graphite powder with 2-10% of graphene content.
Most major graphene producers are currently focused on smaller scale production of high-quality graphene for high-value applications. The past 18 months have seen a marked increase in graphene collaborations, agreements, investments, and product launches. Products are now coming to market across multiple sectors and regional markets. New products and developments incorporating graphene include body temperature regulating fabrics, jackets, coolants, sensors, automotive composites, wheelchairs, supercapacitors for public transport, cigarette filters, membrane technology, wearable technology for athletes and OLEDs.
Investment companies have invested multimillion dollars in small-scale producers and product developers in seat warming technology, solar panels, and batteries. This shows no sign of abating with electronics giant Huawei launching the Mate 20 X phone smartphone incorporating a graphene cooling film (graphene was supplied by The Sixth Element Materials). Automotive company Ford has also announced that it will become the first automaker to use graphene parts in its vehicles, starting with the Mustang and F-150, in collaboration with Eagle Industries and XG Sciences.
The high-value applications of graphene such as high-frequency transistors and touch screens are still some way off from full commercial realization, due to high production costs and the finite scalability of synthesis methods. Most volume based graphene producers target the conductive additives market for their materials, for application in batteries, composites, conductive inks, and paints/coatings. In high-end markets, the value of graphene is evident and makes penetration more likely (comparable to quantum dots in displays). However, in large volume markets, they face significant challenges from incumbent materials.
Multi-walled carbon nanotubes
The global market of carbon nanotubes is generally segmented by multi-walled carbon nanotubes (MWCNT), single-walled carbon nanotubes (SWCNT), and others (DWCNT, FWCNT). Currently, MWCNT comprises the biggest share in terms of sales volumes and production capacities. Demand for MWCNT is mainly from composites, energy storage, and electronics industries. As electroconductive additives, MWCNT is mainly used for anti-static plastics in the automotive industry, electronics packaging, and lithium-ion batteries. There are several large companies with MWCNT production capacities of hundreds of tons per year. Prices of MWCNT have reduced significantly in recent years.
Single-walled carbon nanotubes
The most remarkable properties of nanotubes are found in SWCNTs, including:
- Incredible strength (they are 100 times stronger than steel at one-sixth the weight)
- Electrical conductivity as high as copper, but five times lighter
- Thermal conductivity as high as diamond (up to 1000oC)
- Huge surface area
- Highest length-to-diameter ratio
- Flexibility
- Thermal stability
- Lightweight
- Chemical inertness (GNTs are compatible with almost all materials)
SWCNTs are vastly superior to MWCNTs in terms of their specific properties. However, they have not been used in industry until the last few years due to the lack of efficient mass production technology and high cost. However, recent mass production technology is making SWCNTs more affordable for use in a range of industries.

Closing the Loop on PCB Etching Waste
09/09/2025 | Shawn Stone, IECAs the PCB industry continues its push toward greener, more cost-efficient operations, Sigma Engineering’s Mecer System offers a comprehensive solution to two of the industry’s most persistent pain points: etchant consumption and rinse water waste. Designed as a modular, fully automated platform, the Mecer System regenerates spent copper etchants—both alkaline and acidic—and simultaneously recycles rinse water, transforming a traditionally linear chemical process into a closed-loop system.
Driving Innovation: Depth Routing Processes—Achieving Unparalleled Precision in Complex PCBs
09/08/2025 | Kurt Palmer -- Column: Driving InnovationIn PCB manufacturing, the demand for increasingly complex and miniaturized designs continually pushes the boundaries of traditional fabrication methods, including depth routing. Success in these applications demands not only on robust machinery but also sophisticated control functions. PCB manufacturers rely on advanced machine features and process methodologies to meet their precise depth routing goals. Here, I’ll explore some crucial functions that empower manufacturers to master complex depth routing challenges.
Trouble in Your Tank: Minimizing Small-via Defects for High-reliability PCBs
08/27/2025 | Michael Carano -- Column: Trouble in Your TankTo quote the comedian Stephen Wright, “If at first you don’t succeed, then skydiving is not for you.” That can be the battle cry when you find that only small-diameter vias are exhibiting voids. Why are small holes more prone to voids than larger vias when processed through electroless copper? There are several reasons.
The Government Circuit: Navigating New Trade Headwinds and New Partnerships
08/25/2025 | Chris Mitchell -- Column: The Government CircuitAs global trade winds continue to howl, the electronics manufacturing industry finds itself at a critical juncture. After months of warnings, the U.S. Government has implemented a broad array of tariff increases, with fresh duties hitting copper-based products, semiconductors, and imports from many nations. On the positive side, tentative trade agreements with Europe, China, Japan, and other nations are providing at least some clarity and counterbalance.
How Good Design Enables Sustainable PCBs
08/21/2025 | Gerry Partida, Summit InterconnectSustainability has become a key focus for PCB companies seeking to reduce waste, conserve energy, and optimize resources. While many discussions on sustainability center around materials or energy-efficient processes, PCB design is an often overlooked factor that lies at the heart of manufacturing. Good design practices, especially those based on established IPC standards, play a central role in enabling sustainable PCB production. By ensuring designs are manufacturable and reliable, engineers can significantly reduce the environmental impact of their products.
