Polymer/Phthalocyanine-Modified BaTiO3 Nanocom posite for Embedded Capacitor Application

摘要

Rapid growing and mixed-signal integration are driving the need for product and component miniaturization in electronics applications. Polymer-ceramic composites have been of great interest as embedded capacitor materials because they combine the processability of polymers with the high dielectric constant of ceramics. Herein the following two technologies are reported in this work to achieve such nanocomposite. 1) Phthalocyanine (Pc)-modified BaTiO3 (see structure in Figure 1. M=Cu, Zn, Ni, etc). 2) Polyamide (PA) /bismaleimide (BMI) as novel matrix (see structure in Figure 2). High dielectric constant over 80 (at 1 MHz) was achieved with modified filler loading ratio of 70vol%.
