Engineers still need to make tradeoffs when trying to achieve improved thermal conductivity in plastics. One of the biggest challenges in plastics design today is efficient heat removal from smaller components, some of which operate at higher voltages. Example: LED arrays are becoming more popular in auto headlamps to conserve energy. Research data presented by DuPont at its pre-K 2007 press conference in Prague show three different approaches: 1) Use of high filler content including carbon fiber achieves a high rate of thermal conductivity but is difficult to mold, 2) Boron nitride coated graphite coupled with copper particles coated with glass also work well, but are not cost effective and also have molding issues, and 3) Use of ceramic particles as fillers does not achieve the level of thermal conductivity required by emerging applications.
University of Southampton researchers have come up with a way to 3D print transparent optical fibers like those used in fiber-optic telecommunications cables, potentially boosting frequency and reducing loss.
