“…Polyimides have the most numerous representation (Table 1); therefore, for this class, the predicted data are closest to the experimental ones [28,31,34]. For such a practically important and extensive class of polymers as poly(arylene ether ketone)s [56,57], the database [15] contains only 41 different structures, so for this class, the verification of predicted data is very interesting. Thus, in this work, a number of poly(arylene ether ketone)s (PAEKs), as well as poly(diphenylene phthalide), which only has a common structural element with one of the PAEKs, were synthesized and studied, and the process of verifying various methods for predicting transport parameters for these polymers was carried out.…”

Three poly(arylene ether ketone)s (PAEKs) with propylidene (C1, C2) and phtalide (C3) fragments, and one phtalide-containing polyarylene (C4), were synthesized. Their chemical structures were confirmed via 1H NMR, 13C NMR and 19F NMR spectroscopy. The polymers have shown a high glass transition temperature (>155 °C), excellent film-forming properties, and a high free volume for this polymer type. The influence of various functional groups in the structure of PAEKs on gas transport parameters was evaluated. Expectedly, due to the higher free volume, the introduction of the hexafluoropropylidene group to PAEK resulted in a higher increase of gas permeability in comparison with the propylidene group. The substitution of the fluorine-containing group on a rigid phtalide moiety (C3) significantly increases the glass transition temperature of the polymer, while the gas permeation slightly decreases. Finally, the removal of two ether groups from the PAEK structure (C4) leads to a rigid polymer chain that is characterized by the highest free volume, gas permeability, and diffusion coefficients among the PAEKs under investigation. Also, theoretically predicted transport parameters were investigated, to further study the structure–properties relationship for the PAEKs. Methods of modified atomic (MAC) and bond (BC) contributions were applied for this purpose (estimation of gas permeation and diffusion). Gas solubility coefficients for PAEKs were forecasted by the “Short polymer chain surface based prediction” (SPCSBP) method. Both the MAC and BC techniques showed reasonable predicted parameters for three polymers, while a significant underestimation of gas transport parameters was observed for C4. The results for all three prediction methods were compared with the experimental data obtained in this work. The predicted parameters were in good agreement with the experimental data for phtalide-containing polymers (C3 and C4), while for propylidene-containing poly(arylene ether ketone)s they were overestimated, due to a possible influence of the propylidene fragment on the indices of the oligomeric chains. MAC and BC methods demonstrated a better prediction power than the SPCSBP method.

Poly(arylene ether)s with different molecular weights were synthesized via a two‐step nucleophilic substitution polymerization by adjusting reaction parameters based on phenolphthalein (PHT) and decafluorobiphenyl (DFBP). The chemical structures and properties were identified by Fourier transform infrared, NMR, gel permeation chromatography, differential scanning calorimetry, thermogravimetric analysis, dynamic thermomechanical analysis (DMA), and so forth. The number‐average molecular weight (Mn) of the resulting polymers was in the range of 23.0–49.3KDa. FPAEs (polyarylether including perfluorobiphenyl structure) were demonstrated to have outstanding thermo‐resistance with 5% weight loss temperature of about 482–520°C (N2) and high‐glass transition temperature (about 240–250°C). FPAEs can be dissolved in conventional organic solvents, possessing excellent film‐forming properties. The good mechanical properties of FPAEs were confirmed by the DMA data, with Young's modulus greater than 1.0 Gpa and modulus retention rate at 230°C >67%. FPAEs also showed good hydrophobicity and low‐water absorption, in particular, FPAE‐1 (FPAE‐1‐5 were the polycondensation products of PHT and DFBP, just the polymerization conditions were slightly modified) exhibited favorable dielectric properties: at 1 MHz, the dielectric constant and dielectric loss was 2.58 and 0.0053, respectively. Thus, FPAE‐1 has broad prospective applications in microelectronic devices and communication technology.

Improving the dimensional stability is significant for fluorinated poly(aryl ether) (FPAE). In this work, zirconium tungstate (ZrW2O8) with negative thermal expansion (NTE) modified by thiol groups is successfully obtained by surface modification with 3‐(trimethoxysilyl)‐1‐propanethiol. Then, the dispersion of ZrW2O8 is improved and a certain crosslinked structure is formed by click reaction between thiols on the surface of ZrW2O8 and allyl groups on the backbone of FPAE. On this basis, the residual allyl groups on the FPAE can undergo addition reaction under heating conditions to further form crosslinked structure. Due to the introduction of photo‐thermal dual crosslinked structure, the dimensional stability of FPAE is significantly improved, and the coefficient of thermal expansion decreased by 64.3% compared to the unoptimized samples. Meanwhile, the dielectric properties are characterized with dielectric constant and dissipation factor of 3.70 and 0.008 at 1 kHz. Finally, the prepared film is used to assemble triboelectric nanogenerators, where the short‐circuit current, open‐circuit voltage and transferred charge is 3 μA, 30 V, and 10 nC, respectively. Crosslinked FPAE with high dimensional stability and high temperature resistance are successfully gained by avoiding the complexity of monomer synthesis and realizing higher performance with the same inorganic filler loading.Highlights Dual crosslinked structure is built by photo‐thermal dual crosslinking reaction. ZrW2O8 gains homogeneous dispersion in polymer matrix by photo‐crosslinking reaction. Introducing ZrW2O8 and dual crosslinked structure raises dimensional stability of film.
