Carbon nanotube thin film laminate resistive heater

This invention describes a flexible heater made by applying a layer of carbon nanotubes onto a textured plastic sheet. The nanotubes are carefully applied to ensure they are pure and not mixed with the plastic, then electrical connections and a protective cover are added. An optional sticky backing allows it to be attached to surfaces.

Why it matters: Since 2016, the cost and purity of carbon nanotubes have improved, and manufacturing techniques for flexible thin-film devices have advanced, making this type of heater more feasible.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedCustom substrate, CNT film deposition, thick film equipment.
