High ionic conductivity is a prerequisite for the application of solid-state polymer electrolyte towards safe and high energy density electrochemical devices. Here we report preparation properties an in-situ polymerized comb-like copolymer-based SPE (PLA/PEG-SPE) with from methyl acrylate functionalized poly(D,L-Lactide) (PLAMA) poly(ethylene glycol) ether methacrylate (PEGMA). A remarkably value 6.9 × 10−5 S cm−1 at ambient temperature maximum 4.3 10−4 60°C were detected, activation 0.2 eV...
This work aims to elucidate how the branching effect of macromonomer influences polymerization, structural features, and solution properties ABn long-subchain hyperbranched polymers (LHPs). Our result reveals that compared with linear AB2 macromonomers, star AB3 macromonomers in suppression chain extension, enhancement self-cyclization during preparation LHPs by "click" due branching-enhanced steric hindrance effect. The combined triple-detection SEC stand-alone LLS studies unfractionated...
Solid polymer electrolytes (SPE) are of great importance for developing the next-generation all-solid-state lithium metal batteries, which featured by their high safety and extraordinary energy density. Herein, using highly efficient azide-alkyne click chemistry, a series long-subchain hyperbranched copolymers from various compositions AB2 macromonomers PCL-2N3 (polycaprolactone) PS-2N3 (polystyrene) were synthesized employed as SPE host. Taking advantage structure, crystallization PCL was...
This work shows how the unique slow diffusion and multi-charge properties of polyelectrolyte ligand dominate catalytic mechanism for water oxidation catalysts.
For the synthesis of N′-benzylidene-2-(2-fluorobiphenyl)propanehydrazides, 2-(2-fluorobiphenyl-4-yl)propanoic acid was esterified to methyl 2-(2-fluorobiphenyl-4-yl)propanoate under microwave irradiation followed by hydrazinolysis. This hydrazide then reacted in an ultrasonic bath with different benzaldehydes afford a series N′-benzylidene-2-(2-fluorobiphenyl)propanehydrazides. Comparison both conventional and ultrasound assisted reactions indicates significant reduction reaction times...
Abstract Post‐polymerization modification (PPM) is one of the most powerful strategy for preparing polymers with functional groups that cannot be synthesized by direct polymerization. So far, numerous experimental efforts have been devoted to stability issue monomer structures during PPM process, but little attention was paid chemical linkages. However, hyperbranched polymers, a minor change linkage unit could lead significant influence on overall and performance polymer materials. In this...
Microwave assisted synthesis of a series 4-hydroxy-N'-(phenylcarbonyl)-2H-1,2-benzothiazine-3-carbohydrazide 1,1-dioxides from sodium saccharin is reported.Sodium o-benzosulfimide was N-alkylated with ethyl chloroacetate followed by base catalyzed ring expansion to six membered 1,2-benzothiazine through Gabriel-Coleman type rearrangement yielding 4-hydroxy-2H-1,2-benzothiazine-3-carboxylate 1,1-dioxide.It later condensed benzohydrazides synthesized various carboxylic acids get the title...
In the title compound, C10H10Cl2N2O2, secondary amide groups are differently twisted relative to benzene ring, with dihedral angles between respective planes of 21.03 (2) and 81.22 (2)°. crystal, mol-ecules connected by N-H⋯O C-H⋯O hydrogen bonds, forming a two-dimensional polymeric network parallel (001). One carbonyl O atoms accepts two H in inter-actions, an R 2 (2)(6) ring motif.
The present experimental studies aim to assess combustion efficiency, engine performance and emission parameters of spark ignition utilizing nano-gasoline fuel which has been formulated by blending transition metal co-doped ceria nano-additives with base through ultrasonic agitation. Many researchers reported the effectiveness nanometal oxide additives in lowering harmful exhaust emissions. Chemically, cerium (CeO2) plays significant role gasoline due its unique redox behavior large oxygen...
