Abstract
A method is for forming a radiation shield around an object. The method includes providing an inorganic paint pigment comprising a fluid matrix, and paint flakes carried within the fluid matrix. Each paint flake includes a common aluminum mirror layer having a first major surface and a second major surface opposing the first major surface, a first plasmonic aluminum reflector layer carried by the first major surface, and a second plasmonic aluminum reflector layer carried by the second major surface. The method also includes coating an outer surface of the object with the inorganic paint pigment.

A method for forming a radiation shield around an object, the method comprising:
- providing an inorganic paint pigment comprising
- a fluid matrix, and
- a plurality of paint flakes carried within the fluid matrix, each paint flake comprising
- a common aluminum mirror layer having a first major surface and a second major surface opposing the first major surface,
- a first plasmonic aluminum reflector layer carried by the first major surface, and
- a second plasmonic aluminum reflector layer carried by the second major surface, each of the first plasmonic aluminum reflector layer and the second plasmonic aluminum reflector layer comprising a first contiguous set of self-assembled aluminum particles having a first thickness and a second contiguous set of self-assembled aluminum particles having a second thickness different than the first thickness;
- and
- coating an outer surface of the object with the inorganic paint pigment.
An inorganic paint pigment comprising:
- a fluid matrix;
- and
- a plurality of paint flakes carried within the fluid matrix;
