“…In the DMA curves of poly(aryl ether ketone)s containing bis-phthalazinone, the loss modulus tends to have only one secondary transition before T g , and a similar double secondary transition peak occurs for poly aryl ether sulfone materials containing a similar monomer. 34,40 For heteroatom-containing polymers, the heteroatom-containing groups in the main chain can move independently, which includes the sulfone group in polysulfone materials, and this might be the reason for the double transitions.…”

A series of poly(aryl ether sulfone)s including bis-phthalazinone moieties (PBPES-Ps) that displayed improved heat resistance were obtained through condensation polymerization. The structures of the PBPES-Ps were investigated by FT-IR, 1 H NMR, and XRD. The heat resistance of the PBPES-Ps can be regulated according to the monomer contents in the polymerization. The glass transition temperature (T g ) of PBPES-Ps was 280−349 °C and the 5% mass loss temperature was up to 514 °C. The PBPES-Ps had high mechanical and thermo-mechanical characteristics, i.e., the storage modulus and the tensile strength of PBPES-Ps were as high as 1.81 GPa and 95.3 MPa, respectively. Furthermore, the storage modulus retention reached 76.5% at 220 °C. With the introduction of the 4,4′-di(4′-1(2H)-phthalazinone)-1,1′-biphenyl (BPBN), both the dielectric loss (D f ) and dielectric constant (D k ) of PBPES-Ps decreased, and the lowest values of D f and D k were 0.0061 and 2.95 at 1 GHz, respectively. The PBPES-Ps' hydrophobicity declined with the increasing BPBN content. In addition, the PBPES-Ps were soluble in conventional solvents like Nmethyl-2-pyrrolidinone as well as 1,1,2,2-tetrachloroethane.

Nine poly(phthalazinone ether ketone) resins were designed and synthesized using three bisphenol and four halogenated monomers. Poly(phthalazinone bisphenol ether ketone) (PPBEK) and poly(phthalazinone ether sulfone ketone) (PPBESK) demonstrated liquid oxygen compatibility (LOC), with PPBEK maintaining its LOC even after 20 days of immersion in liquid oxygen. The liquid oxygen compatibility mechanism of the polymers in the presence of force‐thermal‐chemical multi‐energy fields was analyzed using techniques such as thermal analysis‐infrared‐gas chromatography (TGA‐IR‐GC), thermogravimetric analysis (TGA), and x‐ray photoelectron spectroscopy (XPS). Carbon fiber (CF) reinforced composites were fabricated using PPBEK and PPBESK as matrices, with CF‐PPBEK composites successfully achieving LOC. The microcracking resistance and mechanical properties of the composites were investigated in liquid oxygen at 90 K. The interaction mechanism between the composites and liquid oxygen was elucidated, providing theoretical guidance and an experimental foundation for the application of resin matrix composites in liquid oxygen storage tanks.Highlights Poly(phthalazinone ether) resins were meticulously designed and synthesized. ·PPBEK and PPBESK exhibited excellent liquid oxygen compatibility. Composites exhibited excellent liquid oxygen compatibility. Composites exhibited excellent low‐temperature performance and heat resistance.

“…This is another obstacle to the application of PAEKs in high-frequency communication and large-scale integrated circuits. Previous studies have shown that polymers with twisted, non-planar molecular junctions often have excellent solubility properties [ 21 , 22 , 23 ]. This is primarily due to the regularity of the molecular structure being disrupted and the ease with which solvent molecules enter the molecule.…”

Non-Coplanar Diphenyl Fluorene and Weakly Polarized Cyclohexyl Can Effectively Improve the Solubility and Reduce the Dielectric Constant of Poly (Aryl Ether Ketone) Resin

et al. 2023

With the rapid development of high-frequency communication and large-scale integrated circuits, insulating dielectric materials require a low dielectric constant and dielectric loss. Poly (aryl ether ketone) resins (PAEK) have garnered considerable attention as an intriguing class of engineering thermoplastics possessing excellent chemical and thermal properties. However, the high permittivity of PAEK becomes an obstacle to its application in the field of high-frequency communication and large-scale integrated circuits. Therefore, reducing the dielectric constant and dielectric loss of PAEK while maintaining its excellent performance is critical to expanding the PAEK applications mentioned above. This study synthesized a series of poly (aryl ether ketone) resins that are low dielectric, highly thermally resistant, and soluble, containing cyclohexyl and diphenyl fluorene. The effects of cyclohexyl contents on the properties of a PAEK resin were studied systematically. The results showed that weakly-polarized cyclohexyl could reduce the molecular polarization of PAEK, resulting in low permittivity and high transmittance. The permittivity of PAEK is 2.95–3.06@10GHz, and the transmittance is 65–85%. In addition, the resin has excellent solubility and can be dissolved in NMP, DMF, DMAc, and other solvents at room temperature. Furthermore, cyclohexyl provided PAEK with excellent thermal properties, including a glass transition temperature of 239–245 °C and a 5% thermogravimetric temperature, under a nitrogen atmosphere of 469–534 °C. This makes it a promising candidate for use in high-frequency communications and large-scale integrated circuits.
