The Recent Advances of Polymer–POSS Nanocomposites With Low Dielectric Constant

Abstract

This study provides a comprehensive overview of the preparation methods for polyhedral oligomeric silsesquioxane (POSS) monomers and polymer/POSS nanocomposites. It focuses on the latest advancements in using POSS to design polymer nanocomposites with reduced dielectric constants. The study emphasizes exploring the potential of POSS, either alone or in combination with other materials, to decrease the dielectric constant and dielectric loss of various polymers, including polyimides, bismaleimide resins, poly(aryl ether)s, polybenzoxazines, benzocyclobutene resins, polyolefins, cyanate ester resins, epoxy resins, and more. Additionally, the research investigates the impact of incorporating POSS on improving the thermal properties, mechanical properties, surface properties, and other aspects of these polymers. The entire study is divided into two parts, discussing systematically the role of POSS in reducing dielectric constants during the preparation of POSS composites using both physical blending and chemical synthesis methods. The goal of this research is to provide valuable strategies for designing a new generation of low dielectric constant materials suitable for large‐scale integrated circuits in the semiconductor materials domain.This article is protected by copyright.

Synergies and applications of polyimides featured low permittivity and high thermal conductivity

“…Firstly, the polarization that affects the variation of permittivity can include four forms, electronic polarization (P e , 10 14 -10 16 Hz), ionic polarization (P i , 10 9 -10 13 Hz), dipolar polarization (P d , 10 3 -10 8 Hz) and interfacial polarization (P int , 10 −3 -10 2 Hz) as shown in figure 1 [22]. Different polarization behaviours would be dominated in specific frequency ranges [23]. Then, the change in the number of polarized molecules is mainly reflected by the free volume fraction (FFV) of the PI molecules, which is negatively correlated with N. Increasing the FFV of PI molecules will decrease the number of polarized molecules per unit volume and reduce the density of polarized molecules of system.…”

Versatile Landscape of Low-k Polyimide: Theories, Synthesis, Synergistic Properties, and Industrial Integration

“…Moreover, the electrical conduction loss is caused by current leakage, which can be divided into volume-limited conduction and electrode-limited conduction . In the low frequency range, the dipoles in the material have sufficient response time and the dielectric loss is mainly due to the electrical conduction loss, which is almost independent of the frequency . However, the response time of the dipoles is decreased, and the relaxation loss is increased at high frequency.…”
