Abstract

Due to the high‐power environments of electronic components, achieving the exceptional dielectric properties and mechanical behavior necessary for electronic packaging materials presents a significant challenge. In this study, a trifunctional maleimide (HTMI) was synthesized by reacting hexamethylene diisocyanate trimer (HDI trimer) with Maleic anhydride (MA), followed by the preparation of Bismaleimide (BMI) resin featuring a micro‐branching structure through its reaction with diallyl bisphenol A (DBA) ether and BMI. The intentionally designed micro‐branching structure resulted in an increase in the free volume within BMI, leading to an 8.8% reduction in the dielectric constant. Additionally, this micro‐branching architecture imparted superior mechanical properties to the BMI resin, as demonstrated by a 140% increase in bending strength and a 149% increase in impact strength of the cured product.

具有低介电常数和高韧性的支化交联结构双马来酰亚胺的成分设计和性能研究

由于电子元件所处的高功率环境，要实现电子封装材料所需的优异介电性能和机械性能是一项重大挑战。本研究通过六亚甲基二异氰酸酯三聚体（HDI 三聚体）与马来酸酐（MA）反应合成了三官能团马来酰亚胺（HTMI），然后通过与二烯丙基双酚 A（DBA）醚和 BMI 反应制备了具有微分支结构的双马来酰亚胺（BMI）树脂。有意设计的微支化结构增加了 BMI 的自由体积，使介电常数降低了 8.8%。此外，这种微支化结构还赋予了 BMI 树脂优异的机械性能，固化产品的弯曲强度提高了 140%，冲击强度提高了 149%。

期刊介绍： Polymers for Advanced Technologies is published in response to recent significant changes in the patterns of materials research and development. Worldwide attention has been focused on the critical importance of materials in the creation of new devices and systems. It is now recognized that materials are often the limiting factor in bringing a new technical concept to fruition and that polymers are often the materials of choice in these demanding applications. A significant portion of the polymer research ongoing in the world is directly or indirectly related to the solution of complex, interdisciplinary problems whose successful resolution is necessary for achievement of broad system objectives. Polymers for Advanced Technologies is focused to the interest of scientists and engineers from academia and industry who are participating in these new areas of polymer research and development. It is the intent of this journal to impact the polymer related advanced technologies to meet the challenge of the twenty-first century. Polymers for Advanced Technologies aims at encouraging innovation, invention, imagination and creativity by providing a broad interdisciplinary platform for the presentation of new research and development concepts, theories and results which reflect the changing image and pace of modern polymer science and technology. Polymers for Advanced Technologies aims at becoming the central organ of the new multi-disciplinary polymer oriented materials science of the highest scientific standards. It will publish original research papers on finished studies; communications limited to five typewritten pages plus three illustrations, containing experimental details; review articles of up to 40 pages; letters to the editor and book reviews. Review articles will normally be published by invitation. The Editor-in-Chief welcomes suggestions for reviews.
