BUSAN, South Korea, Dec. 1, 2022 /PRNewswire/ -- Thermally conductive polymer composites consist of fillers oriented in certain directions that form pathways for heat flow. However, conventional methods to control the orientation of these fillers are energy-intensive and require surface modifications that can deteriorate the quality and properties of these materials. Now, researchers from South Korea have developed an energy-efficient method to control the orientation of the fillers without the need for surface modification, resulting in improvement in thermal conductivity.

Key Points: 
  • Now, researchers from South Korea have developed an energy-efficient method to control the orientation of the fillers without the need for surface modification, resulting in improvement in thermal conductivity.
  • Owing to their lightweight natureand flexibility, thermally conductive polymer composites are applied between a heat source and a sink in electronics to dissipate the generated heat to the surroundings.
  • Thermally conductive polymer composites such as thermal paste are used in phones, laptops, even in batteries.
  • Apart from improving thermal conductivity, fillers are also used to alter a composite's optical, electrical, and mechanical properties.
