The research and application progress of resin-based composite materials in the field of electrical insulation has attracted considerable attention and emerged as a current research hotspot. This review comprehensively summarized the research and application progress of resin-based composite materials in the field of electrical insulation, providing detailed insights into their concept, properties, and preparation methods. In addition, a comprehensive evaluation of the electrical insulation performance, mechanical properties, and thermal properties of resin-based composite materials was presented, along with an in-depth analysis of their current application status. Despite the immense potential and development opportunities of resin-based composite materials, they also face several challenges. This review serves as a valuable reference and resource for researchers in related fields and aimed to promote further research and application development of resin-based composite materials in the field of electrical insulation.

Enhancing Thermal Conductivity in Polymer Composites through Molding-Assisted Orientation of Boron Nitride

“…As the density of electronic components and power density continue to escalate, thermal management has emerged as a crucial determinant of performance stability and the longevity of electronic devices [ 1 , 2 ]. Polymer-based thermally conductive materials, known for their excellent electrically insulating attributes, light weight, and ease of processing, have begun to supplant traditional metal-based counterparts, demonstrating significant potential in thermal management applications [ 3 , 4 ]. However, polymers are inherently thermally insulating, and enhancing their thermal conductivity involves either augmenting the intrinsic thermal conductivity of the polymers or incorporating high-thermal-conductivity fillers [ 5 , 6 , 7 , 8 , 9 , 10 ].…”

“…In contrast, integrating thermally conductive fillers into a polymer offers a more feasible strategy for attaining high thermal conductivity in these materials. Notably, the Polymers 2024, 16, 1169 2 of 13 inclusion of thermally conductive but electrically insulating fillers preserves the outstanding electrically insulating properties of polymers [3,4]. However, electrically insulating fillers primarily rely on phonon heat conduction and necessitate higher filler concentrations to establish a continuous thermally conductive network and minimize interface thermal resistance, thereby enhancing thermal conductivity.…”
