Recent Progress of Low Dielectric and High-Performance Polybenzoxazine-Based Composites

Abstract

With the rapid advancement of intelligent electronics, big data platforms, and other cutting-edge technologies, traditional low dielectric polymer matrix composites are no longer sufficient to satisfy the application requirements of high-end electronic information materials, particularly in the realm of high integration and high-frequency, high-speed electronic communication device manufacturing. Consequently, resin-based composites with exceptional low dielectric properties have garnered unprecedented attention. In recent years, benzoxazine-based composites have piqued the interest of scholars in the fields of high-temperature-resistant, low dielectric electronic materials due to their remarkable attributes such as high strength, high modulus, high heat resistance, low curing shrinkage, low thermal expansion coefficient, and excellent flame retardancy. This article focuses on the design and development of modification of polybenzoxazine based on low dielectric polybenzoxazine modification methods. Studies on manufacturing polybenzoxazine co-polymers and benzoxazine-based nanocomposites have also been reviewed.

Design and Verification of Thermosetting Benzoxazoles with Excellent Dielectric Properties and Thermostability via the Materials Genome Approach (MGA)

“…Accordingly, studies on polymers with high thermal stability and low dielectric constants have drawn substantial interest within academic and industrial circles. Many efforts have been made to develop polymers with high-temperature resistance and low dielectric resin, akin to polyimides, − polyarylether, − polyquinoline, , and poly­(benzoxazole). , Unfortunately, there are few polymer dielectrics that are capable of excellent overall performance.…”

The improved properties of benzoxazines based on molecular design and blending, and related applications, are illustrated in Fig.…”

“…Interested readers are directed towards monographs and other outstanding reviews for further information. 3,4,6,8,17–22,24–26,28 However, among these reviews, applications of benzoxazines in coatings have not been summarized even though a number of researchers have explored benzoxazine based coatings.…”

High-Thermal Stable Epoxy Resin through Blending Nanoarchitectonics with Double-Decker-Shaped Polyhedral Silsesquioxane-Functionalized Benzoxazine Derivatives

“…The toughness of epoxy resins can be improved via inter-molecular interactions between the thermosetting polymers (PBZ) and the O-H functional groups [ 35 , 36 , 37 , 38 , 39 ] that occur after carrying out the polymerization. POSS hybrids mixed into a polymer can be categorized as end-chain or side-chain varieties and created using mono-functional or multi-functional POSS nanomaterials [ 40 , 41 , 42 , 43 , 44 , 45 , 46 ]. The latter leads to the formation of insoluble crosslinking structures.…”
