"Innovative Market Solutions to Help Businesses Make Informed Decisions"
The global carbon nanotubes market size was USD 4.94 billion in 2020 and is projected to grow from USD 5.32 billion in 2021 to USD 10.52 billion in 2028 at a CAGR of 10.2% during the 2021-2028 period. The sudden rise in CAGR is attributable to this market’s demand and growth, returning to pre-pandemic levels once the pandemic is over. The impact of COVID-19 has been unprecedented and staggering, with CNT witnessing a negative demand shock across all regions amid the pandemic. Based on our analysis, the global market exhibited a decline of 2.2% in 2020 compared to the average year-on-year growth during 2017-2019.
Carbon nanotubes are used in applications that require high strength, electrical conductivity, durability, lightweight properties, and thermal conductivity compared to other conventional materials. Rapid demand from integrated circuits, lithium batteries, fuel cells, drug delivery, solar PV cells, hydrogen storage, and field emission displays. They act as antennas for electromagnetic devices and radios. Conductive CNTs are used in brushes for commercial electric motors as they improve thermal and electrical conductivity as they stretch through the plastic matrix of the brush. Rising commercialization and ramp-up of the installed capacities with advancement in technology to improve the overall product quality and develop more advanced products are the key trends driving the carbon nanotubes market growth.
COVID-19 Outbreak to Temporarily Shutdown the Manufacturing Plants
The COVID-19 pandemic has negatively impacted every region, every business, and every facet of life. China and the U.S. were among the worst-affected countries during the initial wave of the COVID-19 outbreak. Both countries are among the major manufacturers and exporters of carbon nanotubes. Due to pandemic restrictions, manufacturing plants were either functioning at reduced capacity or had to be temporarily shut down, causing supply chain disruption. Additionally, mobility restrictions imposed during the lockdown resulted in logistical challenges, making it difficult to procure raw materials and transport finished products. Trade restrictions imposed by several countries, a limited workforce, and a scarcity of freight containers resulted in an unprecedented scenario that posed challenges for manufacturing and end-use industries. The market is still developing and mostly research-oriented. Pandemic restrictions have affected research activities, hampering development.
Most manufacturing companies have been reported to have rigorously adhered to COVID-19 regulations to protect their employees and keep manufacturing facilities operational. As the global economy began to recover from the pandemic's setbacks and gain traction, the emergence of a new, more contagious delta variant has substantially increased the level of uncertainty in trade activities. The United States is currently facing a substantial surge in COVID cases due to the delta variant. However, because of massive vaccination drives conducted within the country and high public awareness, the impact of rising cases is likely to be less severe than the first wave on trade and industrial operations.
