Building the Graphene Ecosystem,

CEO MESSAGE
대표이사 홍병희

Since our founding in 2012, we have been dedicated to transforming
graphene—often referred to as a "dream material"—into a tangible industrial reality.
We believe graphene will drive a new wave of innovation across
key manufacturing sectors, including semiconductors, displays, and consumer electronics.

Despite the collective efforts of researchers and industry pioneers in
building the graphene ecosystem, significant technical challenges
and barriers to commercialization still remain.
At Graphene Square, however, we are overcoming these challenges
through our proprietary core technologies, continuously expanding the boundaries
of what graphene can achieve and bringing its applications closer to real-world industries.

With our large-area graphene mass production facility based on CVD,
located in the Blue Valley Industrial Complex in Pohang,
we are proud to mark the beginning of the "Graphene Valley."
This initiative will serve as a global hub for the graphene industry,
driving innovation not only in Korea but across the world,
and contributing to the advancement of key industries.

Graphene Square will continue to serve as a bridge between science and industry.
We are committed to advancing research, business, and social value in a balanced
manner, with the vision of positioning Korea as a global leader in graphene technology.
Your continued interest and support empower us to pursue
greater challenges and shape a better future.

Thank you.
