Gerdau Graphene launches two performance-enhancing graphene additives for water-based paints and coatings

Gerdau Graphene has launched two new additives specifically formulated for the paint and coatings industry: NanoDUR and NanoLAV. The new additives, produced with the company's proprietary G2D technology, utilize graphene nanoplatelets to deliver improved performance for water-based paints and coatings — without altering pH levels. The additives also reduce or eliminate the need for some traditional manufacturing inputs, additives, and processes, which can lower production costs while improving sustainability and reducing environmental impact.

"Until recently, it has been virtually impossible for coatings manufacturers to upgrade product performance, slash manufacturing costs, and improve sustainability at the same time — it simply couldn't be done. Now, the application of carbon nanomaterials, such as graphene, in commercially available additives has made this possible and will act as a game-changer for the industry," said Alexandre de Toledo Corrêa, CEO of Gerdau Graphene. "NanoDUR and NanoLAV represent the new performance, economic, and sustainability edge for coatings manufacturers, enabling them to leapfrog competitors across the value chain. These are the newest in our growing portfolio of graphene additives and we're excited to partner with industry leaders to develop even more novel, powerful applications for graphene."

Researchers use graphene oxide to design a material that can channel mechanical energy in a preferred direction

Researchers from Japan's RIKEN Center for Emergent Matter Science, National Institute for Materials Science (NIMS) and Nagoya University have developed a material, based on graphene oxide nanofillers embedded in a hydrogel, that can channel mechanical energy in one direction but not the other, acting in a “nonreciprocal” way. Using the composite material - which can be constructed at various sizes - the team was able to use vibrational, up-and-down movements, to make liquid droplets rise within a material. Using the material could make it possible to use random vibration usefully to move matter in a preferred direction.

To create the unique material, the group used a hydrogel - a soft material made mainly of water - made of a polyacrylamide network and embedded graphene oxide nanofillers into it, at an angle. The hydrogel is fixed to the floor, so that the top part can move when subjected to a shear force but not the bottom. The fillers are set at an angle, so that they were angled clockwise from top to bottom. When a shear force is applied toward the left, from the direction the nanofillers are leaning, they tend to buckle and hence lose their resistance. But in the other direction, where they are facing away from the force, the applied shear merely makes them stretch even longer, and they maintain their strength. This allows the sheet to deform in one direction but not the other, and in fact the group measured this difference, finding that the material was approximately 60 times as resistant in one direction than the other.

Directa Plus receives new graphene-enhanced textiles order from partner Grassi

Directa Plus and Italian clothing group Alfredo Grassi have expanded their partnership in military and public sector workwear after a new public sector contract. To meet the contract, Grassi has ordered tens of thousands of linear meters of graphene-treated lining worth more than €700,000, which is to be delivered in 2023.

The two companies have been working in partnership since 2017 and Directa Plus said this latest deal would add to the recurring revenue stream from its patented Graphene Plus PTC technology.

Black Swan Graphene announces shipment for industrial park concrete pour

Black Swan Graphene has announced a shipment of product to Nationwide Engineering Research & Development ("NERD") for an upcoming concrete pour in the United Kingdom. This commercial shipment follows the announcement of a partnership between Black Swan, NERD, and Arup Group Limited, aimed at providing an integrated supply chain and a turnkey solution to the concrete and construction industries.

The upcoming concrete pour will use Black Swan's graphene product in a total of 180 tonnes of concrete for the construction of an industrial park near Redruth, Southwest England. The industrial park will offer 14 industrial units ranging from 2,500 and 3,500 sq ft, with the graphene-enhanced concrete being used for the external concrete aprons. This is the second time this developer has used the technology provided by NERD, having previously used it in the construction of an industrial park in Warminster, approximately 170 km west of London, United Kingdom.

Zentek updates on graphene-based icephobic technology for drones

Following its September 2022 announcement on testing of icephobic coating technology, Zentek has now reported successful drone testing, where thrust was maintained under calibrated icing conditions of freezing drizzle and freezing rain in an outdoor, real-world environment. The drone with Zentek's icephobic coating applied to the propeller blades hovered under the outdoor icing rig and, on all tests conducted, maintained flight until the end of the battery life of the drone. The same drone with uncoated propeller blades rapidly lost the ability to maintain flight, according to the Company.

Zentek shared that the coating is a functionalized graphene oxide augmented elastomer.

Researchers develop graphene-based wearable touch panel for virtual-real handwriting interaction

Researchers from China's Qingdao University and Shenzhen University have developed a graphene-based proof-of-concept for a skin-friendly and wearable textile-based touch panel that converts a person's forearm into a keyboard or sketchpad. The three-layer, touch-responsive material translates what a user sketches or types into computer pictures.

Computer trackpads and electronic signature capture devices are not common in wearables. Researchers have proposed constructing flexible touch-responsive panels out of clear, electrically conductive hydrogels, but these materials are sticky, making writing on them difficult and uncomfortable for the skin. As a result, the research team sought to combine a comparable hydrogel into a comfortable fabric sleeve for drawing or playing computer games.
