Graphene is a two-dimensional material obtained by separating a single layer of carbon atoms from charcoal, also known as graphite. It exhibits excellent electrical conductivity, surpassing copper, a primary material for wiring, by 100 times. It boasts remarkable flexibility even with increased surface area and maintains its electrical conductivity even when bent. Depending on the content and weaving method of graphene yarn, it simultaneously achieves various functions such as antibacterial properties, UV protection, infrared radiation blocking, insulation, cooling, breathability, electrostatic prevention, and flexibility.
