Grafoid is a private company based in Canada that aims to produce graphene on a commercial scale using their proprietary extraction process. The company is also active in high-growth, scalable graphene projects, patents and material applications. In May 2013, the company (together with Graphite Zero, of which it holds a majority stake) launched the MesoGraf brand of affordable high-quality graphene materials under the MesoGraf brand.
Grafoid is collaborating on Graphene research with Focus Graphite (which used to own 40% of Grafoid, although it is only a minor shareholder now) and the two companies are still linked by a 10-year offtake agreement. Grafoid is also co-developing graphene-based polymer and non-polymer applications with Rutgets University.
In July 2013 the company raised $3.5 million from private investors. In February 2015, Grafoid received a $8.1 million CAD ($6.46 USD) grant from the Canadian government. In March 2016 China's Xiamen signed a strategic agreement with Grafoid and agreed to buy up to 20% of the company.
In May 2019 Grafoid launched a new company called Grafprint3D to develop and produce graphene inks and 3D printing inks.
The latest Grafoid graphene news:
Canadian graphene developer Grafoid announced that it launched a new company, called Grafprint3D, to develop and produce 3D printing materials based on Grafoid's MesoGraf graphene - although Grafprint3D's current materials are actually graphene inks for screen printing and inkjet printing and not 3D printed ones.
Grafoid says that initially the new company will focus on wearable device fabrication with biocompatible polymers, biomaterial substrates for cell therapy engineering research, and rapid product prototyping with printable advanced nanomaterials.
Grafoid and Stria Lithium have announced the successful co-development of an innovative graphene-based filtration membrane to separate Magnesium and Calcium from salars. Developed in concert with Grafoid Inc. – a related company sharing common directors and an active partner in the 2GL Green Energy Technology Strategic Alliance – this filtration membrane functions as a precursor that promotes efficiencies within the conventional process of recovering Lithium from Salts.
The Companies explain that the key method of recovering commercial lithium has remained the same for over half a century: by evaporating brines collected from salars and salt lakes in evaporation ponds. However, this method is time consuming and can take a year or more - leading to large amounts of salt waste. In addition, Magnesium and Calcium are also present and form impurities that must be refined out in the process. With the demand for lithium outpacing the recovery rate of lithium from brine – faster and more efficient methods of recovery will be critical to supply the growing demand.
Grafoid and Liquinex to collaborate on water purification solutions using MESOGRAF graphene-based filtration technology
Grafoid has announced a strategic partnership with Liquinex, a company specializing in waste water engineering needs, to provide commercial scale water treatment solutions using Grafoid’s MESOGRAF graphene-based filtration technology.
The graphene-based filtration products are said to be readily scalable to meet the rising commercial demands making them ideal for industrial level, niche applications such as the concentration of beverages, treatment of crude oil/water mixtures, biofuel and industrial wastewater treatments where reverse osmosis (RO) is not suitable due to the fouling tendencies when concentrated liquids are purged through RO cartridges.
Grafoid, the Canadian graphene R&D, investment and technology company, announced the development of its GPURE Graphene Polymer nano-porous membrane intended for next generation Li-Ion battery applications.
The GPURE graphene polymer membrane (GPM) was developed as a chemically inert, freestanding membrane using graphene composites to test ion selectivity using both monovalent and divalent ions. Ion selectivity is a key requirement for a semi permeable membrane in a Li-ion battery structure. By protecting the sensitive electrode materials from unwanted chemical species GPURE GPM diffuses only energy harvesting monovalent ions such as Li+, Na+ etc.
Grafoid has announced the development of the GPURE Membrane Platform, consisting initially of six next generation GPURE Graphene-Polymer membrane technologies intended for industrial markets.
GPURE Graphene-Polymer membranes include:
- GPURE (A) - A high performing, free-standing membrane developed for water desalination applications
- GPURE (B) - A stable, large area membrane developed for wastewater filtration suitable for very high temperature operating applications
- GPURE (C) - A large area free-standing membrane developed for water filtration pre-treatment and may be suitable for use in gas separation applications and may be used as a lightweight component for automotive and sports equipment applications
- GPURE (D) - A large area membrane that may be used for gas separation and sensing applications
- GPURE (E) - A large area membrane intended for use in gas separation applications
- GPURE (F) - May be applied as a graphene varnish for wood surfaces to protect against moisture, UV light and high temperatures
