Multifunctional thermal conducting and/or radiating particles and array having the same, and fabrication method thereof

A composite array formed by a mass of multifunctional thermal conducting and/or radiating particles;

• wherein the multifunctional thermal conducting and/or radiating particle is composed of a core and a shell, comprising:
• a core including a core particle having thermal conductivity lower than that of a particle included in the shell;
• and
• a shell including high-thermal conductive particles having thermal conductivity higher than that of the core particle,
• wherein the shell is 5˜60 volume % of the core, and a diameter of the core is 50˜90% of a diameter of the whole multifunctional thermal conducting and/or radiating particle, and
• wherein the multifunctional thermal conducting and/or radiating particle has a diameter of 5.5 μm or less.

A composite film comprising one selected from a group of multifunctional thermal conducting and/or radiating particles, composite arrays, an organic binder, or a combination thereof;

• wherein the multifunctional thermal conducting and/or radiating particle is composed of a core and a shell comprising:
• a core including a core particle having thermal conductivity lower than that of a particle included in the shell;
• and
• a shell including high-thermal conductive particles having thermal conductivity higher than that of the core particle;
• wherein the composite array is formed by a mass of the multifunctional thermal conducting and/or radiating particles,
• wherein the shell is 5˜60 volume % of the core, and a diameter of the core is 50˜90% of a diameter of the whole multifunctional thermal conducting and/or radiating particle, and
• wherein the multifunctional thermal conducting and/or radiating particle has a diameter of 5.5 μm or less.
