UK-based AEH Innovative Hydrogel Limited was established in 2018 to develop food-based fully recyclable hydroponic gel.
AEH's hydrogel (branded as GelPonic) is graphene-based, and it is designed to reduce food production costs, improve quality and lower environmental impact.
Aerogel Core has been established by University of Bath scientists, supported by Innovate UK funding.
The Company specializes in ultra-light, graphene-based ‘aerogels’ that can be used for soundproofing and heat-shielding for the aerospace and automotive industries.
The innovative and environmentally friendly aerogels are synthetic, porous materials manufactured by replacing the liquid component normally found in gels with gas.
The team has developed a way to use graphene to produce aerogels that retain their shape and strength, without the gel structure collapsing.
Altered Carbon (AC) was founded in 2018 in Bristol Robotics Laboratory, where the company is based.
Anaphite, located in the UK, aims to incorporate graphene into battery materials, via an inexpensive and scalable process that fits directly into existing cell production lines.
The incorporation of graphene into Li-ion batteries is meant to improve battery life and charging times.
Applied Nanotech is a PEN company and functions as the PEN Design Center focused on developing new products for the PEN family of companies using nanotechnology approaches. Its team of PhD level scientists and engineers works with companies to solve technical problems and create innovations, producing a competitive advantage for the PEN family.
Applied Nanotech was founded in 1989, went public in 1993, and for the majority of its history focused on next generation display applications. However in late 2005, to diversify from one "make or break" technology, it expanded its focus to other areas leveraging its previous work. From 2006 to the present, it has made substantial progress in these areas. The company has organized its efforts into four divisions each of which has substantial potential: Nanomaterials, Nanoelectronics, Nanosensors, and Nanoecology.

Cambridge Raman Imaging Limited (CRIL) was registered in the UK in 2018. Its focus is on bringing to market high speed, label-free Raman imaging instruments. The first application uses graphene in medical imaging, aiming to deliver better patient outcomes through faster and more accurate tumor diagnosis and treatment.
CamGraphIC was spun out of Cambridge University to commercialize graphene photonic circuits technology for telecoms and datacoms. The company is supported by co-founder Frontier IP Group Plc.
COnovate (previously called SafeLi) was founded on December 15, 2016 by Drs. Carol Hirschmugl and Marija Gajdardziska-Josifovska from the University of Wisconsin-Milwaukee.
A university-incubated startup, the company commercializes products based on a unique material called COPHITE (graphene monoxide), with an initial focus on Lithium Ion Batteries.
Dongxu, also known as Tungshu, was established in 1997 and its headquarters and R&D center are located in Beijing. With roots in the optoelectronic display industry, it now has become a industrial investment enterprise focused on the optoelectronic display and renewable energy industries, while also covering financing, urbanization and real estate. The Tunghsu Group, with yearly revenues of over $5 Billion USD, has 40 subsidiaries under direct management with 100% share control or majority control, among which two are listed companies.
Tunghsu Group has successively invested in and established over 20 production lines of flat panel display glass substrates and a production base for graphene, sapphire and color filters in Beijing, Shijiazhuang, Zhengzhou, Wuhu, Chengdu, Mianyang, Yingkou, Kunshan, Zhenjiang and other cities. It has recently released the G-king, a graphene-based battery line, signed agreements with graphene companies (ICN2 included) and invested in many graphene initiatives.
Dreamfly Innovations (DFI) was founded in India in September 2021 by IIT and IISc Grads with 16 years of collective experience in the battery space.
DZP Technologies was founded in 2008 in the UK to develop specialty materials, formulations, and technologies for emerging industries. The Company works with its customers to create materials for a range of markets, from consumer electronics and wearables, to 3D-printing and renewable energy.
DZP specializes in aqueous materials and formulations which are both user- and environmentally-friendly.
