Special Issue Information

Dear Colleagues,

When combined, nanocomposites such as polymeric and ceramic-based nanocomposites are multiphase or hybrid materials with remarkably different properties from the bulk components. Nanocomposites differ from conventional composite materials widely used today due to the nanoscale dimensions of the filler phase and the exceptionally high surface-to-volume ratio of this phase. As a result, compared with traditional composites, nanocomposites always hold many unique mechanical, thermal, electrical, magnetic, optical, biological, or catalytic properties, which are controlled by many factors like local chemistry, mobility, morphology, or crystallinity.

Additionally, nanocomposites often offer a combination of several properties, thus making them even more attractive as multifunctional materials for the future, with appealing potential applications in many industrial fields such as aviation and aerospace, automobile, microelectronic devices and power equipment, healthcare, energy materials, sensors, national defense, and military industry and other systems.

Therefore, the objective of this Special Issue is to explore all aspects of polymeric and ceramic nanocomposites and nano-engineered composites, from nanoparticles, synthesis, morphology, structure, interfacial bonding, aging, properties (e.g., mechanical, thermal, electrical, optical, wear, barrier, flame retardancy, antifouling, sensing, and drug release) and characterizations, processing to potential applications.

When the power converter connects to the high-frequency transformer breaks through the bottleneck and reaches a frequency of 100 kHz or even higher, the high-frequency transformer’s inter-turn insulation faces more serious high-frequency discharge and high-temperature problems. In order to improve the service performance of oil-immersed high-frequency transformer insulation paper, composite K-BNNS particles are prepared by ultrasonic stripping, heat treatment, and thermomagnetic stirring. Then, K-BNNS particles are mixed with PMIA (polymeric m-phenylenediamine solution) slurry to produce composite aramid paper. And the effects of K-BNNS particles with different contents on the thermal conductivity, dielectric properties, partial discharge properties, and mechanical properties of aramid paper are explored. It can be found that, when the addition of composite particles (K-BNNS) is 10%, the comprehensive performance of composite aramid paper is the best. Compared with Nomex paper, the in-plane and through-plane thermal conductivity of composite insulating paper F-10 increased by 668.33% and 760.66%, respectively. Moreover, the high-frequency breakdown voltage increased by 48.73% and the tensile strength increased by 2.49%. The main reason is that the composite particles form a complete thermal conductive network in the aramid paper matrix and a large number of hydrogen bonds with the matrix, which enhances the internal interface bonding force of the material and changes the charge transport mechanism.
