High-tech household energy storage pigment

Why are melanin-based electrochemical energy storage devices so expensive?

The main challenges in realizing melanin-based electrochemical energy storage devices are the poor film processibility due to its high insolubility or poor dispersibility in aqueous solvents and the high cost of the synthetic melanin (Mel-Syn) being over $800 per gram 6, 7, 8.

Can pigment eumelanin be used for energy storage?

The pigment eumelanin has recently been positioned as a promising candidate for solving issues in health, sensors, and energy storage. However, the low solubility of eumelanin in aqueous solvents, difficult film processibility, and high cost have hindered the material from wide deployment.

Can Mel-BSF increase the value of melanin in energy storage devices?

Due to the scalability of the harvesting process and the investigated improved solubility, Mel-BSF seems to be a promising candidate to increase the value of melanin as an affordable organic electrode material in energy storage devices.

Is there a sustainable source of melanins for electrochemical applications?

Nevertheless, a ubiquitous sustainable source of melanins for a broad range electrochemical applications still needs to be addressed.

What is a high IR reflectance paint?

High mid-infrared reflectance (up to ~80%) is achieved, which is more than 10 times as conventional paints in the same colors, efficiently reducing both heat gain and loss from/to the outside environment. The high near-IR reflectance also benefits reducing solar heat gain in hot days.

What are the pigment nanoparticles used in chemistry?

The pigment nanoparticles including PB (ACROS Organics), iron oxide (Sigma-Aldrich, 99%), goethite (Sigma-Aldrich, 30 to 63% Fe), and ZnO (Sigma-Aldrich, 99.9%) were used as purchased.
