“…Silicone‐based flame‐retardant epoxy resins mainly introduce the polysiloxane structures (including the silicone oil, silicone resin, and siloxane copolymers) into the curing network structure, which is an efficient, low toxicity, nondripping, and environmentally friendly smoke suppression flame retardant system. In comparison, phosphorus atoms have a weaker binding ability of the atomic nucleus, resulting in the large degree of atomic polarization and electronic polarization degree for phosphorus‐based flame‐retardant epoxy resins 63 …”

Epoxy resins are widely utilized in electronics, electrical components, and communication equipment for polymer‐based wave‐transparent composites. However, the dielectric constant (ε) and dielectric loss (tanδ) of common epoxy resins are relatively high (ε for 3.8–4.2; tanδ for 0.018–0.025), and the corresponding impact resistance is poor. Thus, it cannot meet the requirements of advanced microelectronic materials. And the epoxy resins prepared by filling the inorganic fillers are difficult to combine the low ε with good machining performance. The ε and tanδ of intrinsic epoxy resins can be decreased by the synthesis of epoxy monomers and curing agents and the optimization of the final curing network. Meanwhile, the use of some special processing methods, such as the electrospinning technology, is also conducive to reducing the ε and tanδ values of final epoxy‐cured resins. The factors affecting the dielectric properties of epoxy‐cured resins, and the common methods to decrease the ε value of epoxy‐cured resins are reviewed in this article. Then, the design, synthesis and research progress of ultra‐low ε epoxy resins are investigated with the relevant academic results. Finally, the development trends and application prospects of the ultra‐low ε epoxy resins are discussed.

To address the shortcomings of poor thermal stability, easy migration, and over‐plasticization of the liquid organic phosphorus flame retardant, cresyl diphenyl phosphate (CDP), we employed halloysite nanotube (HNT) as a carrier to load CDP, thus forming a novel composite (HNT‐CDP). The results demonstrated that the CDP loaded into HNT channels was 41 wt%. HNT‐CDP composites exhibited higher thermal stability, water resistance, and flame retardancy than mixtures of HNT and CDP in epoxy resin (EP). With a loading of 15 wt%, the limiting oxygen index of EP/HNT‐CDP increased to 48.3 and achieved a V‐0 rating in UL94 tests. Additionally, HNT‐CDP exhibited better inhibitory effects on the peak heat release rate and total heat release of EP, as well as a longer time to ignition, compared with the mixture. Moreover, as opposed to EP/HNT + CDP, EP/HNT‐CDP exhibited a significant 114.5% increase in tensile strength. These excellent thermal, water resistance, and mechanical properties can be primarily attributed to the loading of CDP by HNT channels. HNT effectively utilizes the channel confinement effect to isolate CDP from directly interacting with EP. The outstanding flame retardancy is mainly due to the synergistic effect between HNT and CDP after the formation of the composite.
