GrafeneX - Graphene Coatings

GrafeneX is a novel technology that creates a platform for the deposition of Graphene and chemically functionalized Graphene coatings.

This enabling process provides Grafoid with the capability to apply its diverse graphene-based coatings to many different types of material substrates with controllable levels of surface coverage, thickness etc. to meet precise end user requirements.

High-performing Graphene Applications

One of the key obstacles to graphene’s broad, universal industrial acceptance is the absence to date of low-cost, high performing graphene applications that can be successfully adapted for use across all industrial sectors. BCC Market Research reports the global market for paints and coatings is anticipated to rise to $164.1 billion in 2021 at a compound annual growth rate of 4.4% from 2016-2021.

Grafoid President and CEO Gary Economo described the GrafeneX technologies as a cost-effective way of laying down graphene coatings on large surface areas.

Mr. Economo said:

“Demand exists for advanced multifunctional technologies capable of successfully disrupting existing business models. We believe our novel, low-cost, coating technologies will encourage interest from those industries developing next generation materials and products.”

Process of Graphene-based Coatings

The GrafeneX process applies Graphene based coatings to substrate materials including polymers, glasses, most metals and refractories. GrafeneX is applied using a proprietary, room temperature, top-down process, designed as an inline continuous surface conversion process compatible with most conventional industrial coil-to-coil and roll-to-roll coating facilities.

In its typical embodiment, the process sequence would include:

  • Surface preparation (cleaning & activation)
  • Graphene oxide application
  • Removal of a benign carrier 
  • Conversion to a Graphene based surface coating

To the greatest degree, the GrapheneX process uses commonly available conversion coating technologies, has a straightforward modular design with a compact footprint that is scalable with production speed. A GrafeneX line can either be retrofitted to existing finishing lines, or function as a stand-alone finishing system.

Mr. Economo said that the GrafeneX line of technologies and services are consistent with Grafoid’s business model for long-term growth and revenue sustainability through joint venturing, licensing and fees for services.

Mr. Economo said:

“As of today, with near zero competition, our GrafeneX technologies position our Company us as a front-runner for large area graphene coatings development.”

GrafeneX enabling characteristics and properties include:

  • The ability to coat large surfaces on metals, semiconductors, ceramics, polymers and glass and the ability to coat fibers, rods and bars.
  • Designed for coil-to-coil and conveyor applications from batch to continuous process.
  • Environmentally safe to benign, flexible technology in terms of coatings uses for: hydrophobic, hydrophilic, super hydrophobic, oleophobic and oleophilic applications.
  • Variable coating thickness (from monolayer to few layer)
  • Many of the physical/chemical properties are tunable. 
  • Good adhesion to substrates (as tested using the ASTM E-335 on aluminum foil) 

GrafeneX coating technology may be used in various industrial, consumer, military, marine, avionics, energy storage, packaging, building materials, electronics, transportation, environmental remediation, intelligent fabrics, sporting goods and medical industries.

Four versions of GrafeneX coatings labeled A to D are available, namely:

GrafeneX (A) which serves many sectors as a precursor coating with hydrophilic properties.

GrafeneX (B) are electrically conductive, hydrophobic coatings, or with tunable electric conduction and may be used for:
