THERMAL REGULATION

Graphene, a nanomaterial with exceptional thermal conductivity, has garnered significant attention in the field of thermal regulation. GRAPHENE can transfer heat very efficiently because of its high surface area and microstructure. This is because electron transport and heat transport can be performed simultaneously.

GRAPHENE also has an excellent ability to absorb and dissipate heat; this is because GRAPHENE has a high surface area, allowing it to absorb and release large amounts of heat. In addition, GRAPHENE can efficiently regulate heat through interaction with specific materials.

Therefore, GRAPHENE has effects on thermal management in various fields. For example, it can be applied in heat dissipation of electronic devices, energy efficiency improvement of buildings, solar industry, heat shock absorbers, etc. This provides economic benefits and energy savings while enabling environmentally friendly thermal management.

Graphene boasts a wide range of potential applications in the apparel industry, with its greatest advantage being the superior thermal management effect it offers.

GRAPHENE-infused apparel can efficiently absorb heat from the environment and transfer it to the body while also releasing body heat to the outside, providing excellent temperature regulation. This makes graphene apparel suitable for sports, hiking, and winter clothing with superior thermal control.

COOLING MECHANISM

The human body dissipates excess heat through various mechanisms, including conduction, convection, radiation, and evaporation (perspiration).
Perspiration is the body's primary response to overheating due to increased environmental temperature, physical activity, or reduced heat dissipation due to clothing or other factors.
Sweating cools your skin as the sweat evaporates, lowering your internal temperature.
Vasodilatation-The blood vessels under your skin get wider. This increases blood flow to your skin where it is cooler — away from your warm inner body. This lets your body release heat through heat radiation.
Graphene can improve heat dissipation by enhancing the natural radiation and convection mechanisms. It can effectively absorb and emit far-infrared radiation, as well as facilitate heat transfer through air movement (convection).

HEAT RETENTION

In cold conditions, most of the body temperature is also lost by radiation.

Vasoconstriction: The blood vessels under your skin become narrower. This decreases blood flow to your skin, retaining heat near the warm inner body.
Thermogenesis: Your body’s muscles, organs, and brain produce heat in various ways. For example, muscles can produce heat by shivering.
Hormonal thermogenesis: Your thyroid gland releases hormones to increase your metabolism. This increases the energy your body creates and the amount of heat it produces.

Perspiration then stops and conduction increases. Special Non-woven, Down, or Fabric in platted construction form reduces the conduction effects on the outer layer while preserving the radiation heat absorbed and emitted by the Graphene located on the inner layer. The capability of Graphene to absorb body radiations and emits far infrared enhances the heat retention properties of winter garments if located closest to the skin.
