Enhanced energy density of poly(arylene ether nitriles) composites filled with surface engineered BaTiO3 nanoparticles

The introduction of nano-sized BaTiO3 (BT) into polymer host matrices brings about promising dielectric and energy storage properties. However, pristine BT tends to aggregate and is difficult to be compatible with polymer matrices, thus requiring surface modification of BT nanoparticles. In this work, gamma-aminopropyl triethoxysilane (KH550) was grafted onto the surface of BT as a shell and amino-functionalized core-shell KH550@BT nanoparticles have been successfully prepared. Thereafter, poly(arylene ether nitrile) (PEN) has been chosen as polymer matrix due to its excellent thermal properties, and xKH550@BT/(1-x)PEN composite films were prepared by solution casting film formation method. The energy density of KH550@BTIPEN composites with 30 wt.% filler loading is 1.30 J cm(-3) (eta = 61.32 %) at 150 MV m(-1), more than 36.84 % increase when compared with pristine PEN polymer (0.95 J cm(-3) at 170 MV m(-1)). Temperature-dependent and frequency-dependent D-E loops confirmed that KH550@BTIPEN composites possess good temperature and frequency stability. (C) 2020 Elsevier B.V. All rights reserved.

1,3-dipolar cycloaddition to the Fe-N=C fragment .17. Diastereoselectivity with C-2- and non-C-2-symmetric chirally N-substituted alpha-diimine ligands, R*-N=C(H)-C(R’)=N-R* and C5H4N-2-C(R’)=N-R*, with dimethyl acetylenedicarboxylate (DMAD) and methyl propiolate (MP). Decomplexation of the pyrrolinone ligand of Fe(CO)(3)(pyrrolinone) complexes

The 1,3-dipolar cycloaddition reaction of Fe[R*-DAB(H;H)](CO)(3) (6k; R*-DAB(H;H)=R*-N=C(H)-C(H)=N-R*) with dimethyl acetylenedicarboxylate (DMAD), in which the R*-DAB(H;H) ligand is C-2-symmetric and is chirally N-substituted, gives the two expected diastereomers with low diastereoselectivity, due to a small difference in the rate constants of the two reactive C=N groups in 6k exposing their re and si faces, respectively. The 1,3-dipolar cycloaddition reaction of Fe(alpha-diimine)(CO)(3) (1, 6m) with DMAD and methyl propiolate (MP), in which a non-C-2-symmetric alpha-diimine ligand (R*-DAB(H;Me) and Py-2-C(R’)=N-R* (R*,R’-PyCa) is chirally N-substituted, gives the two expected diastereomers with medium to high diastereoselectivity. The diastereoselectivity with the non-C-2-symmetric alpha-diimine ligands, which have only one reactive imino group, depends on the size of the chiral group R*, the distance of the chiral group to the reacting centers, and the type of dipolarophile. The two starting complexes (1 and 6m) exist in solution in the form of two rapidly interconverting diastereomeric conformers I and II. In contrast to the C-2-symmetric case, the free energies of activation for the two different conformers and their respective concentrations may be quite different here. The diastereoselectivities could not be influenced by variation of temperature, solvent, or the additional ligand. Kinetic resolution by a cycloreversion reaction could be excluded by the use of a chiral additional ligand and an achiral alpha-diimine ligand (i-Pr, H-PyCa, or i-Pr-DAB(H; H)). X-ray crystal structures have been determined from the respective diastereomeric mixtures of the pyrrolinone complex 5cks and the [2.2.2] bicyclic product 7aks. The structures of the [2.2.2] bicyclic product 4aks and of the free pyrrolinone ligand 8als have been determined using diastereomerically pure products. The 5-(2-pyridyl)pyrrolin-2-one ligands 8 are decomplexed from their precursors 5 by Me(3)NO, air oxidation, exchange by CO, and oxidative reactions with dihalogens or H2O2.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 13676-54-5 is helpful to your research. Quality Control of Bismaleimide.

Electrolytic partial fluorination of organic compounds. 83. Anodic fluorination of N-substituted pyrroles and its synthetic applications to gem-difluorinated heterocyclic compounds

Anodic fluorination of N-substituted pyrroles was carried out in MeCN containing supporting fluoride salts such as Et3N-nHF (n = 2-5) and Et4NF-4HF with use of platinum electrodes under constant current conditions. Anodic fluorination of N-methyl- and N-p-tosylpyrroles having an electron-withdrawing cyano group proceeded smoothly to provide the corresponding fluorinated products in moderate to excellent yields, while anodic fluorination of N-methylpyrrole devoid of an electron-withdrawing cyano group did not take place and a polymeric product was formed at the anode surface. In sharp contrast to the cases of N-methylpyrroles, even N-p-tosylpyrrole devoid of an electron-withdrawing cyano group underwent anodic fluorination efficiently. Diels-Alder reaction of 5,5-difluoro-1-methyl-3-pyrrolin-2-one (2e) derived from anodic fluorination of 2-cyano-1-methylpyrrole (2a) with various dienes was carried out to provide the cycloaddition products in excellent yields. Furthermore, Michael reaction of 2e with various nucleophiles was also successfully carried out to provide the Michael addition products in good to excellent yields.

The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules. In my other articles, you can also check out more blogs about 13676-54-5. Formula: https://www.ambeed.com/products/13676-54-5.html.

Enhanced thermal conductivity of carboxyl nitrile butadiene rubber composites with low-cost poly(catechol/polyamine) modified Al2O3 via biomimetic method

With the miniaturization, integration, and functionalization of the electronic components, heat dissipation in the electronic devices has become a challenging issue. Owing to high polarity, carboxyl nitrile butadiene rubber (XNBR) is usually employed as a dielectric material in the electronic devices. However, low thermal conductivity of XNBR hardly satisfies the increasingly stricter demands for heat dissipation. Herein, we used low-cost poly (catechol/polyamine) (PCPA) to modify Al2O3 nanoparticles via biomimetic method for enhancing the interfacial interaction between the Al2O3 filler and XNBR. The ortho-polyphenols in catechol were oxidized into orthoquinone groups in the alkaline solution. Then, the ortho-quinone groups formed a cross-linked structure to obtain PCPA via the Michael addition or Schiff base reaction with amine. The process decreased the interfacial thermal resistance and phonon scattering, resulting in an enhanced thermal conductivity. When the Al2O3-PCPA nanoparticles content was 30 vol%, the thermal conductivity of XNBR based composites reached up to 0.51 W/ mK, which was 3.19 times that of pure XNBR (0.16 W/mK). The proposed method has potential applications in large scale production of thermally conductive composites in industries, such as electronic packaging materials and thermal management materials.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 13676-54-5 help many people in the next few years. Recommanded Product: 13676-54-5.

Design and characterisation of vitrimer-like elastomeric composites from HXNBR rubber

The present study aims at the incorporation of vitrimer-like properties into elastomeric composites as a promising approach towards the sustainable production of rubber-based materials. In particular, hydrogenated carboxylated nitrile butadiene rubber (HXNBR), as a technically relevant high-performance rubber, is covalently cross-linked with epoxy group-functionalised calcium silicate (Esilicate) across its pending carboxylic acid moieties. Reaction with the reactive functions attached on the filler surface results in the formation of b-hydroxyl ester linkages at the HXNBR-Esilicate interface, which undergo thermo-activated transesterifications in the presence of a suitable catalyst. Topology rearrangements in the composites are confirmed by stress relaxation measurements at elevated temperatures. Comparison with an unfilled reference network reveals that the extent of stress relaxation can be mostly maintained upon the addition of the reactive filler even at large quantities. The Esilicate serves as both cross-linker and reinforcing filler, leading to a significant enhancement of the mechanical properties.
