Kukil Graphene Files Patent Application for 'Thermal Decomposition Deposition Graphene Synthesis and Classification Device'

[Asia Economy Reporter Eunmo Koo] Kukil Graphene continues to file patents related to graphene.

Kukil Graphene, a subsidiary of Kukil Paper, announced on the 2nd that it has filed a patent for "Low-temperature transfer-free thin-film graphene including a thermal CVD deposition source and classification device and its manufacturing method."

This patent is a manufacturing technology that directly grows large-area graphene with a new defect-free concept, complementing the drawbacks of existing graphene manufacturing methods that synthesize high-quality graphene over a wide area at low temperatures using titanium.

In particular, it applies a thermal decomposition method to the graphene thin-film deposition source used in graphene synthesis in 'Roll to Roll' equipment, instead of the conventional plasma method. This method is expected to facilitate graphene synthesis by being used additionally to the existing plasma deposition source.

A company official explained, "It is a method of adding a Thermal CVD deposition source to the existing plasma deposition source during low-temperature transfer-free thin-film graphene synthesis in Roll to Roll," adding, "It has the advantage of polarizing graphene particles of various sizes, unreacted substances, and particles that may occur during graphene synthesis to select graphene particles, while simultaneously improving the thin film properties and controlling the deposition speed."
