MCR Safety launches graphene-enhanced work gloves

Personal protection equipment maker, MCR Safety, recently introduced CT1071, a new Cut Level ‘E’ safety glove made with graphene fibers. It offers a choice of different coatings designed for different tasks and working environments. CT1071 has a 15-gauge shell specifically designed to take advantage of the ultra-lightweight nature of the new fibers. It’s a Cut Level ‘E’ glove yet it’s reportedly 25% lighter than similar gloves offering the level of protection. It is also designed to be comfortable and easy to wear.

As this fiber isn’t blended with any glass or steel, the high-level cut protection is maintained throughout the life of the glove. No fiber breakage means high durability, high comfort and no irritation. The diaphanous Nitrile Micro-Foam coating enables enhanced grip, even in oily conditions.

Martinrea wins automotive industry award for graphene-enhanced brake lines

Martinrea International, a global automotive supplier of value-added lightweight structures and propulsion systems (that has a collaboration with NanoXplore), was named a 2022 Automotive News PACE Award winner at the awards ceremony on September 19. 

Martinrea was recognized for its brake lines with GrapheneGuard, which is said to be the first use of graphene in an automotive brake line application. Martinrea recognized the potential of graphene and developed the revolutionary GrapheneGuard coating technology which incorporates graphene into nylon. The development of GrapheneGuard is a convergence of material science innovation and process engineering that brings to the automotive market a brake line coating that reportedly has unmatched properties. The material can provide up to 25 percent weight savings while simultaneously demonstrating superior strength, greater abrasion protection, and improved chemical resistance, all while utilizing current manufacturing equipment and processes.

Haydale supplies graphene to NeoEnpla for use in food packaging

Haydale has started to supply South Korean plastics developer NeoEnpla with functionalized graphene nano-platelets (GNPs) for use in food packaging. Functionalized using Haydale's patented HDPlas® technology, the GNP-enhanced thermoplastic has been used to manufacture an initial sample range of food storage zipper bags and biodegradable plastic bags.

LLDPE and LDPE (low density polyethylene) are widely used in food packaging and are ideal for food storage due to their high resistance to moisture, tearing and chemicals. The graphene-enhanced zipper bags have reportedly shown an increase in tensile strength of 31% compared to non-graphene LLDPE (linear low-density polyethylene) zipper bags. In addition, the increased mechanical strength of the graphene zipper bags allows light weighting of the plastic, reducing the film thickness from 90µm to 60µm per bag.

Researchers use green chemistry approach to synthesize graphene oxide/silver nanocomposites

Researchers from Pakistan have reported a green approach to the synthesis of graphene oxide/silver nanoparticle nanocomposite.

Metallic nanoparticles (NPs) have various benefits in the field of electrochemistry. Because of their small size, nanoparticles may enhance the contact area of the electrode in use. Furthermore, metallic nanoparticles may boost the rate of mass transfer and provide quick electron transference, increasing the sensitivities of the used electrodes. Silver nanoparticles (AgNPs) are relatively low cost and have distinct physical and chemical characteristics that make them helpful in several optical, chemical, and catalytic functions. Nanoscale composites of metallic nanoparticles and graphene oxide have promising applications in energy storage, supercapacitors, and electronics.

Levidian and Adamant to collaborate on development of graphene-enhanced composite materials

Levidian Nanosystems and Adamant Composites Limited have signed a joint development agreement (JDA) to collaborate on enhancing composite materials with Levidian’s unique graphene.

Over the next three years, the two companies will work together to incorporate Levidian’s sustainable graphene in a range of composite materials. Levidian uses plasma chemistry to crack methane into hydrogen and graphene. This process means their graphene has no batch-to-batch variation, a very small number of layers, and a positive environmental impact. The addition of graphene to composite materials and components will lead to improved process times while augmenting physical properties.
