We have demonstrated that the resistance against electrochemical migration of epoxy resin used as a printed wiring board can be improved by adding a small amount of silica nanofillers. Three patents were submitted based on this result. Next, iron nanoparticles were filled into epoxy resin, which resulted in the development of insulating materials with low eddy-current loss, high permittivity, and high permeability.Complex electric modulus is the inverse of complex permittivity. Relaxation phenomena due to charge transport in polymer, which are dominant in a low frequency range, become evident by showing frequency-dependent electric modulus spectra. We have done this analysis for various polymers, and the results were summarized in papers, which are now under review. Time-domain spectroscopic measurements at THz frequencies were also done for several polymers, and the results were analyzed by quantum chemical calculations.

我们已经证明，可以通过添加少量的二氧化硅纳米填料来改善用作印刷布线板的环氧树脂电化学迁移的阻力。根据此结果提交了三项专利。接下来，将铁纳米颗粒填充到环氧树脂中，这导致开发具有低涡流损失，高介电常数和高渗透率的绝缘材料。通过显示频率依赖的电气模量光谱，由于聚合物中电荷转运而引起的弛豫现象变得明显。我们已经对各种聚合物进行了此分析，结果总结在论文中，这些论文正在审查中。对于几种聚合物，还进行了THZ频率下的时域光谱测量值，并通过量子化学计算分析了结果。
