Abstract
The invention relates to an encapsulated metal particle comprising a core encapsulated in a shell, wherein the core comprises a metallic substance, and wherein the shell comprises a insulating substance. The invention also relates to a polymer composition comprising a plurality of the encapsulated metal particles, a mixture comprising a plurality of encapsulated metal particles and plurality of polymer particles, and the use of the encapsulated metal particle as an additive for increasing the thermal conductivity and/or radio frequency (RF) conductivity of a matrix substance such as an adhesive.
Claims23
A plurality of encapsulated metal particles, the particles comprising a core encapsulated in a shell, wherein the core is homogeneous and comprises a metallic substance, and wherein the shell is in direct contact with the core and comprises glass;
- wherein the encapsulated metal particles have a number median diameter (Dn50) of from 3 μm to 20 μm as determined by optical microscopy.
A plurality of encapsulated metal particles according to any one of the preceding claims, wherein the core comprises a plurality of particles of the metallic substance.
A plurality of encapsulated metal particles according to any one of the preceding claims, wherein the core further comprises a non-metallic substance.
A plurality of encapsulated metal particles according to any one of the preceding claims, having a substantially spherical shape or a faceted shape
A polymer composition according to claim 9 or 10, or a mixture according to claim 12, wherein the encapsulated metal particles are present in an amount of from 5% to 85% by weight, based on the total weight of the polymer composition or mixture.
