Graphene cotton swabs are harmless to human body, because graphene itself is a carbon material, and carbon is the most common material around life, which is harmless to human body.
In fact, graphene originally exists in nature, but the single-layer structure is difficult to peel off. Graphene is stacked layer by layer to form graphite, and the graphite with a thickness of 1 mm contains about 3 million layers of graphene. Pencil gently across the paper, leaving traces may be several layers or even just a layer of graphene.
Precautions:
Cotton swabs cannot be reused. If used repeatedly, it will affect the wound recovery. There are many things in life that we cannot predict, just like accidents. It is inevitable that there will be some small accidents in daily life, and sometimes it may cause harm to your body. At this time, it is necessary to apply medicine to the wound with a disposable cotton swab.
Graphene:
Graphene is a two-dimensional carbon nano-material, which has a hexagonal honeycomb lattice and consists of carbon atoms with sp hybrid orbitals. Compared with the existing lithium-ion batteries, the future mobile phone battery material substitutes are expected to increase the power by 45% and have a longer life.
In addition, as a better electrical conductor, the charging speed of graphene battery can also be faster. The basic characteristics of graphene are high strength, flexibility, thermal conductivity and optical properties.
Many scientists and researchers say that graphene is one of the most interesting and widely used substances in history. Because graphene is the thinnest, lightest and strongest material in the world, it is not only strong, flexible and transparent, but also the best conductor of heat and electricity in the world, which can withstand different electrical characteristics.
