Accordingly, the DC conductivity results could interpret the peak value phenomenon by percolation threshold of MWCNTs. In addition, at the fixed content, the dielectric constant of epoxy-based nano-composites with ozone functionalized MWCNTs was lower than that of pristine ones....
High dielectric constant (high-k) polymer composites are of great interest for embedded capacitor applications. Previously, we demonstrated that epoxy—alu... J Xu,CP Wong - 《Journal of Electronic Materials》 被引量: 35发表: 2006年 High thermally conducting composites obtained via in situ exfolia...
Epoxy/BaTiO3 composite embedded capacitor films(ECFs) were newly designed for high dielectric constant andlow-tolerance (less than 5%) embedded capacitor fabricationfor organic substrates. In terms of material formulation, ECFsare composed of a specially formulated epoxy resin and latentcuring agent, an...

The relative dielectric constant (10 kHz) of alumina was found to increase reversibly (by up to 13%) with compressive stress (up to 18 MPa). The effect of stress on the relative dielectric constant diminishes with increasing stress, such that it is almost absent when the stress exceeds ...
helps to maintain a constant input voltage. It also lowers the PDN impedance. However, a higher Dk will result in increased dielectric loss,crosstalk, andEMIissues. In order to balance power and signal integrity, it is advised to opt for a hybrid stack-up of high and low Dk PCB materials...
