Samsung says new “Wonder Material” can make phones ultra-thin and flexible


Samsung today announced that it has discovered a “groundbreaking method” to commercialise synthesising graphene, a material more durable than steel with high flexibility, ideal for use in wearable devices and smartphones.

Along with high flexibility and durability, Graphene also boasts of being a million times thinner than paper, which is another property very useful for displays in smartphones as well as in future wearable devices.

Synthesizing graphene on a large scale was previously quite costly, and involved combining small grapheme particles to make a larger piece of the material. But Samsung’s method overcomes these difficulties:

Samsung claims to have overcome these obstacles using a new method that synthesizes graphene as a single crystal on a larger scale, allowing for the graphene to retain the electrical and mechanical properties that make it such an attractive material. Being able to synthesize graphene on a single crystal has long been a goal of the world’s graphene scientists, who are scattered around the world, with major centers of research in the U.S., Japan, China and South Korea.

Graphene’s electron mobility is a 100 times faster than silicon, the material currently used in smartphone chips. It can reportedly make internet a 100 times faster, based on research by University of Bath.

Graphene will let Samsung (and other manufacturers) make wearable products that are much different that the current crop of smartwatches. Samsung and LG have already introduced a few smartphones with curved, bendable screens, but the Korean company refuses to disclose what the exact applications of graphene will be in its future products.
