Conductive patterns are formed using formulations containing metallic particles, which may be copper. These metallic particles may be coated with a binder material that improves adhesion during photosintering of the formulations. The binder contains chemistry suitable for it to be removed from the particles in a separate process such as drying or thermal sintering. The coating is a non-volatile organic compound attached to the metallic particles with a minimum thickness oxide coating. The organic coating improves a coefficient of thermal expansion value match between the metallic particles and the substrate, which may be polymeric.

A dielectric layer is directly applied onto the surface of a heat sink part. For example, the composition for making the dielectric layer may be made into a paste or ink and then printed as a paste or ink, or applied with some other equivalent method, such as a lamination technique. The electrical circuit traces are then printed in a similar fashion onto the dielectric layer in the required pattern for whatever circuitry is to be applied. That circuitry (e.g., circuit elements) is then attached to the electrical traces as needed for the particular application.

Silicon dioxide particles can reinforce the mechanical properties of an epoxy matrix. Combining carbon nanotubes with the icon dioxide particles to co-reinforce the epoxy matrix achieves increases in compression strength, flexural strength, compression modulus, and flexural modulus. Such composites have increased mechanical properties over that of neat epoxy.

A base material or composite material such as graphite, may be combined with another material, such as aluminum oxide or polyimide, to produce a new insulating thermal management material. The base material may be impregnated with another metal to create a composite base material.

Reflective color inks are used, such as for signage applications and as an electronic display medium and material. The reflective color inks comprise a core-shell particle that includes a core particle coated with a molecular surface coating. One example of such a particle is using a core of a polystyrene type of material that has a relatively low refractive index, with a high reflective index acrylic copolymer added as the shell material.
