Story summary

Massachusetts Institute of Technology (MIT) researchers have developed a lightweight polymer film, 2DPA-1, with near-perfect gas impermeability rivaling graphene.
The polymer is built from melamine monomers and forms ultrathin sheets through hydrogen bonding, enabling scalable production.
A 60-nanometer coating of 2DPA-1 extended the lifespan of perovskite crystals used in solar cells.
Its impermeability could protect infrastructure from corrosion and improve food packaging, while enabling nanoscale resonators for electronics.
