Graphene thermal conductivity - introduction and latest news - Page 3

It was reported that OnePlus' Nord 5 Series, set to launch at the beginning of July, will feature a thermal management system with Cryo-Velocity VC cooling, offering a 7,300 mm² heat dissipation surface area. It will also include flagship-grade graphene thermal technology, similar to the OnePlus 13, delivering a thermal conductivity of 1,800 W/m-K. 

According to the company, "This comprehensive cooling solution covers all key heat sources including CPU, cameras, and battery, ensuring consistently smooth performance even during intensive use and gameplay."

Haydale has provided a trading update highlighting the recent commercial progress of its JustHeat product line: a low-power, graphene-based heating system. According to Haydale, the product has now received UL certification, a critical regulatory milestone that enables the commercial sale of the JustHeat system in the US and Canada. 

It was reported that there is "strong demand" in the UK for JustHeat from social landlords. To date, Haydale says it has secured commitments for over 40 pilot installations across Welsh housing providers.

ViewSonic has launched the XG273-4K-OLED gaming monitor in China, that features a 26.5-inch QD-OLED panel with a 3840 x 2160 resolution and a refresh rate of 240Hz. It is priced at 6499 yuan (approximately $900).

The display was developed by Samsung Display and uses a fanless thermal system that includes a full graphene sheet and an aluminum heat sink. This setup aims to deliver stable, silent performance over long periods. 

Researchers from Japan's Keio University and Waseda University explain that graphene has substantial potential for on-chip nanoscale light sources, due to its small size, high brightness and fast-modulating blackbody radiation sources, but a known problem is the need for transfer processes when mechanically exfoliated or chemical vapor deposited graphene are used, resulting in low productivity and degradation of graphene quality. 

To address this issue, the team fabricated a graphene-based thermal light emitter by using an etching-precipitation method that does not require the transfer process. Infrared and visible light emission was observed from the central constricted area, forming a hot spot. Raman measurements confirmed that defect healing occurred in the central hot spot of graphene due to the annealing effect caused by Joule heating. The team also demonstrated that the device has long-term luminescence stability. 

PC maker Acer has released multiple announcements about new and upcoming AI-powered laptops, desktops, earbuds, and smart rings. Among these, the Company unveiled a slim Predator Triton 14 AI gaming laptop which Acer called 'the industry's first laptop with graphene thermal interface materials (TIM) in the CPU to help keep it cool'. A similarly appointed laptop, the Predator Helios Neo 14 AI will also be available, along with a Predator Orion 3000 gaming desktop that houses a INtel Core Ultra 7 processor and the same GPU as the two laptops.

The Predator Triton 14 AI is aimed at creators, professionals, and gamers who need substantial power in a lightweight build. What is known about the graphene thermal interface material on the CPU is that it is said to deliver 14.5% better heat dissipation compared to standard thermal grease. Dual 6th Gen AeroBlade metal fans and a vapor chamber further improve cooling.

After using graphene cooling tech in previous products like the GT Neo 5 model and GT 2 series, mobile phone brand Realme has announced that its GT 7 series will also make use of graphene-based colling technology, or what was described as: "industry-first graphene IceSense cooling design".

The company says the theme, “Power that Never Stops,” reflects its focus on sustained performance and battery life. 

Researchers from Hefei University and Chinese Academy of Sciences (CAS) have developed a novel 3D-printed graphene/polymer double-layer composite featuring high anisotropic thermal conductivity that offers improved photothermal and electrothermal performance for advanced ice control applications. 

Graphene is known for its outstanding thermal and electrical conductivity, particularly its strong anisotropy—high in-plane conductivity and much lower through-plane conductivity. To capitalize on this property, the researchers used dual-nozzle fused deposition modeling (FDM) 3D printing to directionally align graphene within a thermoplastic polyurethane (TPU) matrix. The resulting double-layer composite, consisting of graphene-enhanced TPU (G-TPU) and neat TPU (N-TPU), achieved an in-plane thermal conductivity of 4.54 W/(m·K), with an anisotropic ratio of about 8.

Haydale Graphene Industries has announced that its JustHeat graphene-based heating system has achieved CE certification, allowing it to be marketed and installed across the UK and EEA. 

This certification marks a significant milestone for Haydale, enabling the company to accelerate the commercial rollout of JustHeat, which offers substantial energy cost savings and reduced carbon emissions compared to traditional heating systems.

Huawei's Mate X6 recently made an appearance at the MWC 2025, along with Mate XT, Watch D2, and the powerful Mate 70 series. While the device contains various features to attract consumers, it gained attention for its unique graphene-based cooling system. 

A cooling system or vapor chamber cooling is a thermal management system that uses evaporation and condensation to dissipate heat from a phone’s components. It prevents overheating, improves performance, and boosts battery life. But Huawei has implemented the next-level cooling innovation into Mate X6 by using graphene sheets. The company showcased how the foldable phone’s graphene sheet easily slices ice cubes into pieces without putting any extra effort or force on it.

Researchers at the Hong Kong University of Science and Technology have used graphene to develop a new 3D printer that can make food layer by layer as it prints, using artificial intelligence (AI) to design complex edible structures. This integrated system combines precision infrared heating with AI-driven design tools to address key limitations in automated food production: maintaining food safety during printing and creating intricate shapes without requiring technical expertise.

Automated food production faces unique challenges compared to manufacturing with traditional materials like plastics or metals. Food must be heated properly to ensure safety, yet maintaining the intended shape during cooking proves difficult. Current 3D food printers operate in two separate steps - first printing cold food paste, then transferring it to an oven or fryer. This approach often leads to deformed shapes and increased contamination risks as the food moves between machines. The new system integrates these steps using a specialized infrared heater made from laser-induced graphene (LIG). This ultra-thin heating element provides precise temperature control, with printed food layers reaching 137°C on the surface and maintaining at least 105°C on the sides throughout the printing process, while using just 14 watts of power - a fraction of the 1000-2000 watts consumed by conventional ovens and air fryers.
