Imagine IM is pleased to announce the successful completion of the first independent field trials of its imgne® X3 coating for geotextiles, conducted on August 18th 2016 in Melbourne, Australia

The global Geosynthetics market is predicted to be worth $16 Billion by 2018 according to analysts, Markets and Markets. The strategy of developing robust leak detection solutions as an entry point into this market was developed after detailed business discussions between Imagine IM and its initial commercial partner, Geofabrics Australia. Imagine IM’s goal is to maximize market presence and credibility in the global geosynthetics market as a precursor to entering other large industrial market verticals. The first revenues from sales and licensing of imgne X3 masterbatch are anticipated to begin in Q1 2017. Imagine IM’s plant based in Geelong has sufficient graphene output capacity to meet current Australian forecast demand and to enable initial orders from foreign markets to be fulfilled.

Following on from successful laboratory testing of samples of imgne X3, Imagine IM commissioned ExcelPlas, a NATA (National Association of Testing Authorities) accredited testing facility, to conduct field trials of commercially-produced imgne X3 coated conductive geotextile to show suitability for commercial application.

The field trials were conducted using standard commercial 2mm thick HDPE geomembrane in a two- layer configuration, ensuring maximum electrical insulation of the tested geomembrane from the earth. This is the most difficult condition for electrical leak detection. Testing was to ASTM standards D6747-04 and D7852-13 using 2m wide, 25m long samples of imgne X3 conductive geotextile, coated on one side only. Deliberate, controlled holes were drilled in the geomembrane from 5mm diameter down to 1mm diameter.

The field trials confirmed that leaks down to 1 mm hole size, the minimum size tested, were able to be detected in the imgne X3 coated geotextiles using normal testing methodologies and equipment for trials of this kind.

Industry standard construction

Notably, no special installation of the geotextiles was required and no welding or other specialized joining of the geotextile was required. Instead electrical joins between adjacent treated geotextile were achieved with a simple 100mm overlap of the geotextile. It was also proven that continuing conductivity could be achieved with overlaps down to only 10mm.

Testing sensitivity was proven to be constant at earth-lead distances from 1m to 20m and holes were successfully detected at 15kV test voltage, in each test, even when there were deformations in the geomembrane. Using standard brush pressure to ensure good geomembrane to conductive geotextile contact during testing, reliable results were registered even at 5kV test voltage. There were no false positives in any of the test results.

In all tests standard installation techniques were used with no special handling or preparation of the imgne X3 coated X3 conductive geotextile nor the geomembrane nor the ground itself.

Phillip Aitchison, COO of Imagine IM said, “We developed imgne® X3 as a graphene-based coating that enables delivery of conductivity in textiles and on other materials without impacting the strength and other characteristics of the materials themselves. The development of a conductive geotextile as Imagine IM’s first commercial application of imgne X3 is a major milestone for us. We have now proven our ability to both manufacture graphene at scale, and also to be able to produce masterbatch solutions that will enable large-scale industrial applications using graphene to make smart materials.”

Chris Gilbey, CEO of Imagine IM said, “These results are extremely gratifying. The intent of using imgne® X3 is to provide a methodology for making geotextiles conductive that will lead to substantial economies for end users and to make leak detection more affordable and more accurate. The next step will be to undertake larger-scale field trials in conjunction with our initial customer, Geofabrics Australasia. We are now confident that our product is manufacturable at scale, and will perform according to the needs of end users, and equally importantly, that it will be able to deliver substantial economies from requiring less complex installation procedures”

About graphene

Graphene’s discoverers were awarded the Nobel Prize in 2010. Graphene is the first two dimensional material and is classed as a “super-material” offering extremely high electrical and thermal conductivity, hydrophobicity, strength, and impermeability to all gases.
