Spray coating blocks wi-fi signals


NaturalNano has developed a spray coating embedded with copper-filled halloysite nanotubes which can be applied to the walls of a room, providing a passive blocking agent for radio frequency (RF) energy.

"Many existing structures including concert and convention halls, movie theaters, and other buildings could benefit from enhanced control over outside radio frequency radiation with a passive, cost-effective solution," said Michael Riedlinger, President of NaturalNano.

They've combined the shielding coating with a technology that enables authorized users to log onto a private network in an area that is otherwise RF shielded. "This technology," said Riedlinger, "also allows the facility operator to potentially charge fees for wireless access within an otherwise RF shielded environment."
