Graphene thermal conductivity - introduction and latest news - Page 3

Rumors suggest that the iPhone 16 may use a graphene heat sink and a metal battery case to promote better heat transfer.

This follows complaints by iPhone 15 users about overheating, which Apple fixed via software, but the iPhone 16 is rumored to have a hardware solution, too. Apple associated the overheating with poorly optimized software and issued a software fix, but more effective cooling may also help.

MSI, a leading manufacturer of gaming hardware, has announced it will be expanding its QD-OLED gaming monitor lineup. The new monitors will reportedly make use of graphene's thermal conductivity in its heat management technology. 

All models will be equipped with the latest generation of QD-OLED panels and will be available in both curved and flat models. Among other thing, the new monitors will enjoy a fan-less design, enhanced with graphene thermal tech for efficient and silent heat dispersion. This further extends the lifespan of these innovative QD-OLED panels.

Graphene Manufacturing Group (GMG) has provided a business update on the commercialization progress of THERMAL-XR powered by GMG Graphene.

GMG has announced it has received forward orders of over AU$400k (around USD$255,000) for THERMAL-XR from various distributors and customers worldwide. Most of the value of these orders is conditional on the in-country approval for the THERMAL-XR to be imported from Australia and sold into that country for the product's initial launch.

The 2023 China International Graphene Innovation Conference (GRAPCHINA 2023), will be held in Shanghai, China from November 10 to 12, 2023. The conference will be jointly hosted by the National Graphene Innovation Center, Shanghai University and the Graphene Alliance (CGIA). Minyang Lu, the Deputy Secretary-General of the CGIA, was kind enough to answer a few questions we had regarding the upcoming conference.

Hello Minyang, thank you for your time. Can you tell us more about the GRAPCHINA event?

The International Graphene Innovation Conference has been successfully held for nine years. The number of participants has set a new record year each year, and its influence has continued to improve. The nine sessions attracted more than 4,000 enterprises, 23,000 participants and 1,200 experts in new materials field, which came from over 30 countries and regions around the world. At present, it has developed into a gathering place, a vanue and an international event for the world's cutting-edge graphene technology achievements and innovative products. The graphene application expo held simultaneously with the conference, will continuously inject new vitality into the development of the global graphene industry by gathering the global graphene industrialization achievements. 

The 2023 International Graphene Innovation Conference (GRAPCHINA 2023) will be organized by the China Innovation Alliance of the Graphene Industry (CGIA), National Graphene Innovation Center (NGIC) and Shanghai University in Shanghai on November 10-12 of the year 2023. This year, GRAPCHINA 2023 will focus on the transformation of scientific and technological achievements, international cooperation, and industrial and supply chain, we will work with end users to create a number of commercialization forums. 

Graphene Manufacturing Group (GMG) has announced that it has commissioned its graphene-enhanced coating blending plant and it is now operational after making its first 1,000-liter blend.

Updating investors on the commercialization progress and sales development of THERMAL-XR, the Company said the blending plant is expected to have the capacity to produce up to 500,000 liters of THERMAL-XR RESTORE coating a year, subject to graphene production, when operating two blends per eight-hour shift, 250 days per year. This capacity enables future service growth well into the future, it added.

At the beginning of June 2023, Asus unveiled the Asus ROG Swift OLED PG49WCD, a gaming monitor that uses graphene for thermal management. Now, Asus has added the PG32UCDM and PG34WCDM gaming monitors, each based on a different OLED panel technology. 

The PG32UCDM uses a 32" QD-OLED panel, produced by Samsung Display. The PG34WCDM monitor is based on a 34" MLA (microlens) WOLED curved panel, produced by LG Display. Both monitors make use of a graphene film for heat dissipation.

Haydale has announced its next collaboration with Cadent, to develop graphene ink-based low-power radiator heaters. The £350,000 three-stage project will run for 12-months and is aiming to develop a tested and validated market-ready product as a cost-effective alternative for Cadent's customers when their gas supply is interrupted.

Following continued success on the low-power, battery operated water heating development, the aim for the latest project is to incorporate the same graphene-ink based technology into different designs to deliver bespoke solutions for a wide range of customer requirements.

Haydale has reported the completion of stages one and two of a three-stage low-power hot water project in collaboration with Cadent Gas. Haydale said the project, first announced in February 2022, aimed to address the challenge of providing a low-power water heating solution during interruptions to the gas supply, particularly for vulnerable customers such as the elderly or disabled.

During stage one, Haydale said it identified four specific and detailed user case scenarios where their graphene ink-based heaters could be effectively used across Cadent's network. That initial stage helped lay the foundation for subsequent development work, with building on the findings - stage two of the project - focused on creating an operational pre-product prototype. The prototype showcased Haydale's functionalized graphene ink, which is printed onto flexible heater sheets which were then enclosed within an insulated 3D printed portable unit.

Researchers from Purdue University have developed patent-pending, solid-state, continuously tunable thermal devices based on compressible graphene foam composites. The devices can dissipate heat, insulate against cold and function across a wide range of temperatures. 

The devices have the potential to improve battery safety and performance in electronic devices and systems like battery thermal management, space conditioning, vehicle thermal comfort and thermal energy storage.

Directa Plus has partnered with Candiani Denim, an Italian textile producer focused on innovation and sustainability, to launch GRAPHITO, an eco-denim textile. The eco-friendly denim textile combines Directa Plus' patented technology, providing antimicrobial and thermal properties, with Candiani Denim's bio-based polymer, which replaces liquid plastic in textile production.

GRAPHITO offers unique benefits by reducing water usage, energy consumption, and carbon emissions by up to 75% throughout the garment's wash lifecycle. Additionally, its antibacterial and antiviral properties enable up to 10 wears per lifecycle, while the thermoregulating properties make it suitable for all seasons.
