Yang, Wenjie;Qi, Jiayue;Tan, Wei;Zhu, Zhengzhu;He, Xian;Zeng, Ke;Hu, Jianghuai;Yang, Gang research published 《 Study on aromatic nitrile-based resins containing both phthalonitrile and dicyanoimidazole groups》, the research content is summarized as follows. In order to prepare aromatic nitrile-based resins with improved curing reactivity, thermal and thermomech. properties, and to clarify the difference in curing activity between dicyanoimidazole and phthalonitrile groups, a novel class of autocatalytic aromatic nitrile-based resins named PNDCI which contains both dicyanoimidazole (DCI) and phthalonitrile (PN) groups were designed and synthesized. A method for evaluating the reactivity of nitrile groups using the absorption wavenumber of FTIR was proposed. PNDCI monomers have demonstrated higher activity for self-promoted curing reactions than benzimidazole-containing phthalonitrile monomers (BIPN). The introduction of DCI can change the curing pathway of PN and inhibit the formation of phthalocyanine ring which is an important cured product of PN resins. The data of TGA, DMA, etc. revealed that the cured products of PNDCIs showed outstanding thermal stability, long-term thermo-oxidative stability at high temperatures (425°C) and thermal mech. properties, which is favorable for the preparation of high temperature resistant resins.

Yildiz, Burak;Arslan, Baris Seckin;Guzel, Emre;Nebioglu, Mehmet;Menges, Nurettin;Sisman, Ilkay;Kasim Sener, M. research published 《 Non-aggregating zinc phthalocyanine sensitizer with bulky diphenylphenoxy donor groups and pyrazole-3-carboxylic acid anchoring group for coadsorbent-free dye-sensitized solar cells》, the research content is summarized as follows. A novel unsym. zinc phthalocyanine complex (PCA-ZnPc-3) containing six 2,6-diphenylphenoxy donor groups and pyrazole-3-carboxylic acid anchoring group has been synthesized and used as a sensitizer for dye-sensitized solar cells (DSSCs). The optical, electrochem. and photovoltaic characteristics were evaluated and compared with the dyes containing the same anchoring group and tert-Bu (PCA-ZnPc-1) or hexylsulfanyl (PCA-ZnPc-2) donor groups, developed by our group. The DSSC with PCA-ZnPc-3 exhibited a higher power conversion efficiency (PCE) of 2.04% as compared to that of PCA-ZnPc-1 (PCE = 1.74%) and PCA-ZnPc-2 (PCE = 1.89%). This enhancement in efficiency may be ascribed to the less dye aggregation and appropriate dye coverage. These results suggest that the incorporation of 2,6-diphenylphenoxy into pyrazole-3-carboxylic acid-based zinc phthalocyanine sensitizers can improve photovoltaic performance of DSSCs.

Phthalonitrile (PN) resin promising material for preparing high-speed and high-frequency electronic packaging because of its unique high temperature resistance and excellent insulation performance. A fluorinated PN oligomer (4,4′-bis (p-perfluoro-phenol-(bis(p-phenol)perfluoropropane-2,2-diyl)-p-oxy-diphthalonitrile) (PFDP)) containing trifluoromethyl and decafluorobiphenyl groups are designed, synthesized, and characterized.

The reactive blend has good processability, and structures of isoindole, triazine ring, and phthalocyanine ring are found in the curing reactions. The fluorinated PN (P-380) shows outstanding thermal stability and mech. properties (5% thermal degradation temperature: 518°C (N₂); 516 (Air), T_{Heat-resistance index}: 268°C, activation energy of thermal decomposition: 334.89 kJ mol^-1, glass transition temperature (T_g) > 400°C). Meanwhile, the fluorinated PN simultaneously exhibited a superior low dielec. constant (D_k, 2.21) and dielec. loss (D_f, 0.01) at 10 GHz. Moreover, the water absorption of the resin is as low as 0.74%, which meets the requirement of dielec. materials.

Seeking high-performance coating with long service life to protect metallic substrates under complex corrosion environment has attracted abundant attention in modern industry. In this work, poly(arylene ether nitrile) (PEN) was applied as protective coating on metallic substrates for the first time, and the cyano-functionalized multiwalled carbon nanotubes (MWCNTs-CN) was introduced to further enhance the corrosion resistance and mech. performance of the PEN coating. Electrochem. results demonstrated that the MWCNTs-CN incorporated composite coating possessed outstanding corrosion resistance that the |Z|0.01Hz remained 196.9 MΩ cm2 after 100 days immersion process in 3.5 wt% NaCl solution, which was 2 orders of magnitude higher than the pure PEN coating. Besides, an evident improvement was investigated from the tensile strength of MWCNTs-CN/PEN coatings, which showed an increment about 20.1% of tensile strength was gained when 1 wt% of MWCNTs-CN was introduced. Benefiting from these advantages, this work is expected to provide a novel insight in high-performance protective coating.
