Cambridge Graphene develops inks based on graphene and related materials using processes developed at the Cambridge Graphene Center. The spin-out company has commercialized graphene inks for novel technology applications.
Researchers at the University of Cambridge in the UK and Jiangnan University in China have designed a low-cost, sustainable and environmentally-friendly method for making conductive cotton textiles using graphene-based ink. These fabrics could lead to smart textiles and interactive clothes that will find applications in healthcare, wearables, Internet of Things and more.
The team created inks of chemically modified graphene flakes that are more adhesive to cotton fibers than unmodified graphene. Heat treatment after depositing the ink on the fabric improves the conductivity of the modified graphene. The adhesion of the modified graphene to the cotton fiber is similar to the way cotton holds colored dyes and allows the fabric to remain conductive after several washes.
A couple of weeks ago we visited Haydale's headquarters and production floor in Ammanford, Wales, UK. Here are our impressions following this visit, the meeting with Haydale's management and a visit to the production floor and processing rooms.
First of all, let's clear up a common misunderstanding: Haydale is not a graphene producer. It buys graphene materials (from several sources) and uses its proprietary plasma process to improve the materials, make them more uniform in quality and tailor them to specific requirements. Haydale then uses these materials to create intermediate materials - inks, coatings, composite materials (and masterbatches) and 3D filaments. Haydale is working with customers to take these materials and use them in various graphene-enhanced products.
Talga Resources has announced that commissioning of all stages of the Phase 2 German pilot test facility has been successfully completed.
In April 2016, Talga announced the commissioning of its Phase 2 processing plant in Germany and has now provided further updates. The pilot test plant is currently configured so that approximately 76% of the input graphitic carbon reports to graphene products (FLG and GNP) and the remaining carbon reports to Talga’s building sector (micrographite) products.
Haydale recently declared the planned acquisition of Innophene, a Thailand-based graphene-enhanced conductive ink and composites manufacturer, in an all-share deal for approximately £311,665. The acquisition marks a significant step in UK-based Haydale Graphene Industries’ expansion into the Asian market, since Innophene’s access to The Thailand Science Park in Bangkok, with its extensive analytical and processing capabilities, provides a platform for it to become the Group’s Far East Centre of Excellence.
Innophene, founded in 2011, has developed (in conjunction with the Thailand National Science & Technology Development Agency) a one-stage exfoliation/dispersion process to create a range of graphene-enhanced transparent conductive inks for inkjet and other printing platforms. They have also now developed a graphene enhanced PLA (Poly-Lactic Acid) resin (commonly used in medical devices and 3D printing).
