Black copper (CuO) Substrates: New product

FLEW has developed its new product called, Black Copper (CuO)” as a general nanomaterial for a wide range of applications. Black copper is a nanostructured surface of pure copper metal sheet. Our simple wet chemical etching method can produce substrates with uniformly distributed nanostructured surface. We can tailor the surface structure by simply changing our etching solution. Currently, we offer two surface morphologies ie; closely packed nanoflakes (NF) and densely aggregated nanoclusters (NC). SEM images below illustrate the different morphology of our two products.

Substrates are available in different sizes and we can selectively create nanostructures on one surface or both.
