High-performance and low-dielectric cyanate ester resin optimized by regulating the structure of linear polyhydroxy ether modifier

Low viscosity and low temperature curing reactive POSS/epoxy hybrid resin with enhanced toughness and comprehensive thermal performance

“…Moreover, the synergistic effect arising from the inherent elastic vibrations of the silicon cage, combined with the exibility of the external chain segments, signicantly contributes to the enhanced toughness of the material. 39,40,[58][59][60][61] Furthermore, the uniform dispersion of rigid nano-llers in the resin matrix is a prerequisite and key factor in achieving high toughness. 41,43,[58][59][60] Therefore, the dispersity of the modier in the matrix was further studied through Atomic Force Microscopy (AFM), Energy Dispersive Spectroscopy (EDS), and X-ray Photoelectron Spectroscopy (XPS), as illustrated by the results in Fig.…”

“…Furthermore, through chemical modication and physical blending, organic-inorganic hybrid nanocomposites can be synthesized for diverse applications. [37][38][39][40] Reactive POSS can participate in the curing reaction of epoxy resin, achieving dispersion at the molecular level, which enhances its compatibility within the epoxy matrix. This characteristic addresses the drawback of inorganic nanomaterials and non-reactive POSS, which tend to agglomerate in resin matrices.…”

An ultralow-k dielectric derived from a fluorinated polybenzoxazole composite film with yolk–multishell mesoporous silica nanostructures

“…For example, many studies have reported on the incorporation of caged polyhedral oligomeric silsesquioxane (POSS) hollow nanoparticles into polymers to prepare low-k nanohybrid materials. [13][14][15][16][17][18][19] However, the obvious limitations such as small size, high-cost and difficulty to synthesize prevent further applications for functionalized POSS monomers. To overcome this limitation, several research groups used inorganic nano-mesoporous silica materials such as MCM-41 and hollow silica spheres as fillers to greatly reduce the k value of silica-based nanocomposites.…”

Regulation and prediction of the dielectric constant and interfacial binding energy of surface modified hexagonal boron nitride/polyphenylene oxide@cyanate ester resin

“…Compared with common polymer materials such as polyether ether ketone (PEEK), 27,28 polyamide (PA), 29,30 polytetrafluoroethylene (PTFE), 31 and bisphenol A dicyanate ester (BADCy) has an extremely low dielectric constant, magnetic permeability, better mechanical properties, and good processability and is widely used as a wave transmission material. [32][33][34] However, its brittleness limits its further application, and therefore, modification of BADCy is required. Common toughening methods include thermosetting and thermoplastic resin copolymerization modification, rubber elastomer modification, and nanoparticle filling modification.…”

“…In order to study the interaction between the polymer and the reinforcement particles, and make a reasonable selection of surface modifiers, molecular dynamics simulation can be effectively used for simulating the interface energy of the two phases, 23–26 thus clearly indicating the interaction relationship between the matrix and the reinforcement and greatly improving experimental efficiency. Compared with common polymer materials such as polyether ether ketone (PEEK), 27,28 polyamide (PA), 29,30 polytetrafluoroethylene (PTFE), 31 and bisphenol A dicyanate ester (BADCy) has an extremely low dielectric constant, magnetic permeability, better mechanical properties, and good processability and is widely used as a wave transmission material 32–34 . However, its brittleness limits its further application, and therefore, modification of BADCy is required.…”
