Technology & Products
Key Products
3D-printable CNT/BNNT composite film for EMI and neutron shielding
Technological Advantage
Proprietary composite structure combining CNT and BNNT in a shell-like arrangement, protected by potential patents (unconfirmed). The technology is at an early research stage at KIST, a government research institute; commercial scalability and IP protection are unverified. Advantage is based on material science rather than process.
Differentiation
Value Proposition
Replaces heavy, rigid, multi-layer shielding with a single, thin, flexible, 3D-printable film that consolidates EMI and neutron protection, enabling weight reduction and design flexibility for satellites, space stations, and wearable protection.
How They Differentiate
KIST's film uniquely addresses both EMI and neutron shielding in a single layer, whereas conventional solutions require separate materials for each (e.g., lead for neutron, conductive composites for EMI). The flexibility and 3D printability also offer advantages over rigid, heavy alternatives.
