Correlation of Dielectric Properties with Structure and H-Bonding for Liquids

“…With the number and power of electromagnetic wave communication devices in development growing, we require an increased understanding and ability to control the dielectric and relaxation properties of a huge variety of materials, mixtures, and composites, which will no doubt lead to many interesting applications. 9 Some of our recent work describes how preparing composite materials which possess H-bonding increases the dielectric relaxation over a broad frequency range, and how application of these composites can enhance antenna bandwidth performance, a novel approach in materials chemistry, and electronic engineering. 10 The static dielectric constants (ε s ) of molecular liquids which associate via H-bonding have been found to be much higher than expected, 11 and attempts to explain these unusually high ε s values using computational methods are available in the literature.…”
