Graphene-based masterbatches: Marrying performance with ecological responsibility

GrapheneUP®, an industry vanguard in manufacturing verified few-layer graphene and a diverse array of graphene-centric intermediary products, announces the debut of MASTERGUP® — an innovative line of thermoplastic masterbatches. This breakthrough harnesses the transformative potential of graphene, setting a new benchmark for sustainability and recyclability within multiple sectors.

Graphene, distinguished by its exceptional strength and conductivity, imparts enhanced thermoplastic properties, including mechanical robustness, thermal stability, and gas barrier properties. These advancements extend the lifespan of products and significantly reduce waste, thereby contributing to more excellent environmental stewardship. Moreover, incorporating the graphene GUP® into thermoplastic matrices elevates processability, streamlining the molding, reshaping, and recycling processes. GUP®-fortified thermoplastics demonstrate remarkable endurance through repeated recycling, mitigating material degradation — a commendable achievement in material sustainability.

Levidian unveils graphene-enhanced prototype truck tire

Levidian has unveiled its first prototype truck tire, combining graphene with carbon black in a new tread formulation. Launched this week at the Tire Technology Expo in Hannover, the graphene-enhanced natural rubber and butadiene rubber tire tread compound, typically used in commercial vehicle tires, has been shown to deliver significant improvements in the mechanical and dynamic properties of the tire.

Independent testing by the Tun Abdul Razak Research Centre (TARRC) has reportedly shown that the addition of Levidian’s 'net zero graphene' can deliver a reduction in rolling resistance of around 23%. Initial results have also indicated potential for reduced compound density that could allow for lighter tires overall. It was said that overall, this could deliver substantial improvements in fuel efficiency of 3-4%.

Researchers develop diamond/graphene composite with high electrical conductivity and hardness

Researchers from China's Zhengzhou University, Ningbo University and Jilin University have used nanodiamonds as precursors to make centimeter-sized diamond/graphene composites under moderate pressure and temperature conditions (12 GPa and 1,300 to 1,500 °C). The composite is reportedly able to conduct electricity while maintaining its ultra-hardness.

This work could pave the way for realizing large-sized diamond-based materials with ultrahigh electrical conductivity and superior mechanical properties under moderate synthesis conditions, which will facilitate their large-scale applications in a variety of fields.

MITO and Vartega team up to create unique graphene-enhanced carbon fiber composite

MITO Material Solutions has teamed up with Vartega, developer of recycled carbon-fiber composites, on a new composite material project. The two companies incorporated MITO’s graphene-based materials into carbon fiber reinforced thermoplastics. Vartega incorporated MITO’s liquefied graphene into their Fenix fiber EasyFeed bundle products – now offered as Fenix Fiber+, which supplies excellent performance with recycled materials.

Because carbon fiber manufacturing is an energy intensive process, waste diversion is a big factor in improving its sustainability. Carbon fiber is typically made from polyacrylonitrile (PAN) precursor fiber that has been stretched and heated at high temperatures to first oxidize and then carbonize the material. These high temperatures coupled with PAN fibers traditionally coming from fossil fuels, means that carbon fiber has a considerable carbon footprint. By diverting waste carbon fibers from landfill, Vartega resets the material’s embodied energy to zero. Vartega’s recycled carbon fiber is 95% less energy intensive than virgin carbon fiber.

Researchers design copper-graphene composites with improved electrical conductivity

Researchers from North Carolina State University and Pacific Northwest National Laboratory (PNNL) recently used shear assisted processing and extrusion (ShAPE) to synthesize macro-scale copper-graphene composites with a simultaneously lower temperature coefficient of resistance (TCR) and improved electrical conductivity over copper-only samples. 

The team's new graphene-copper composite with an improved ability to conduct electricity could lead to more efficient electricity distribution to homes and businesses, as well as more efficient motors to power electric vehicles and industrial equipment. The team has applied for a patent for the work, which was supported by the Department of Energy (DOE) Advanced Materials and Manufacturing Technologies Office.
