Photocatalytic color switching of redox imaging nanomaterials in rewritable media

摘要

The manufacture of photocatalytic color switching of redox imaging nanomaterials for rewritable media is disclosed. The new color switching system is based on a photocatalytic redox reaction that allows reversible and fairly fast color switching in response to light irradiation. According to an exemplary embodiment, the color switching system can include a photocatalyst and an imaging media. Due to the photocatalyst, UV light irradiation is accompanied by a distinct color change and can rapidly reduce redox imaging nanomaterials, while the resulting reduced system can be exposed to visible light irradiation or heating in air conditions. , Can return to the original color state. The superior performance of the new color switching system promises potential use as an attractive rewritable media to meet increasing sustainability and environmental protection needs.
