Abstract

The synthesis of a low dielectric constant polyimide (PI) with a polyhedral oligomeric silsesquioxane (POSS) cross-linked structure is presented. A non-planar conjugated diamine monomer (FSNH2) with two -CH=CH2 reactive groups was first synthesised in a two-step process, and then two polyimides were synthesized by PSS-Octavinyl (OVPOSS) substituted, FSNH2 and dianhydride. OVPOSS cross-linked polyimides have good thermal stability and low dielectric constant. 6FDA-FSNH2-OVPOSS(6FPI-3) can reach a minimum dielectric constant of 2.08 (108 Hz) and a dielectric loss of 0.008 (108 Hz). In addition, the cross-linked structure of the OVPOSS and polyimide chains prevents the agglomeration of OVPOSS to a certain extent and improves the tensile strength and elongation at break of the polyimides, which has great application potential in large-scale integrated circuits.

基于多面体低聚倍半硅氧烷交联的体侧基聚酰亚胺：降低介电常数和改善机械性能

介绍了一种具有多面体低聚倍半硅氧烷（POSS）交联结构的低介电常数聚酰亚胺（PI）的合成。首先采用两步法合成了具有两个-CH=CH2反应基团的非平面共轭二胺单体（FSNH2），然后用PSS八乙烯基（OVPOSS）取代、FSNH2和二酐合成了两种聚酰亚胺。OVPOSS交联聚酰亚胺具有良好的热稳定性和低介电常数。6FDA-FSNH2-OVPOSS（6FPI-3）可以达到2.08（108Hz）的最小介电常数和0.008（108赫兹）的介电损耗。此外，OVPOSS和聚酰亚胺链的交联结构在一定程度上防止了OVPOSS的团聚，提高了聚酰亚胺的拉伸强度和断裂伸长率，在大规模集成电路中具有巨大的应用潜力。

期刊介绍： Health Services Management Research (HSMR) is an authoritative international peer-reviewed journal which publishes theoretically and empirically rigorous research on questions of enduring interest to health-care organizations and systems throughout the world. Examining the real issues confronting health services management, it provides an independent view and cutting edge evidence-based research to guide policy-making and management decision-making. HSMR aims to be a forum serving an international community of academics and researchers on the one hand and healthcare managers, executives, policymakers and clinicians and all health professionals on the other. HSMR wants to make a substantial contribution to both research and managerial practice, with particular emphasis placed on publishing studies which offer actionable findings and on promoting knowledge mobilisation toward theoretical advances. All papers are expected to be of interest and relevance to an international audience. HSMR aims at enhance communication between academics and practitioners concerned with developing, implementing, and analysing health management issues, reforms and innovations primarily in European health systems and in all countries with developed health systems. Papers can report research undertaken in a single country, but they need to locate and explain their findings in an international context, and in international literature.
