The dielectric findings showed that a blend containing 40% of CA by weight had a dielectric constant of 2.9 and an electrical conductivity of 1.26 x 10-11 S cm-1 at 100 Hz and 20 degrees C while exhibiting better mechanical rigidity in the rubbery state than neat PLA. In...
For example, pure ice has a dielectric constant of 3.2 and loss factor of 0.003 at 0 °C while liquid water at the same temperature has an ε′ of 79 and an ε″ of 21. As can be seen in Figures 1 and 2, the higher the moisture content, more dramatic the change in dielectric ...
The dielectric constant of electronic polarization is K = n2, where n is the refractive index. The dipolar response can be tuned over a broad range. Compared with highly correlated dipoles in ceramics such as ferroelectric ceramics, polymers exhibit lower dipole moment and the dipolar correlation....
PCB Dielectric Constant Measurements, Three Ways February 25, 2025 by Dan Maloney 6 Comments FR4 is FR4, right? For a lot of PCB designs, the answer is yes — the particular characteristics of the substrate material don’t impact your design in any major way. But things get a little ...
