Constructing nanocomposites with robust covalent connection between nanoparticles and polymer for high discharged energy density and excellent tensile properties

Journal of Energy Chemistry 2022年第5期31卷 195-205页

作者： Jiachen Ma Yabin Zhang Yan Zhang Luqing Zhang Shuxiang Zhang Xuchuan Jiang Hong Liu shandong Provincial Key Laboratory of Fluorine Chemistry and Chemical Materials School of Chemistry and Chemical EngineeringUniversity of JinanJinan 250022ShandongChina Institute for Advanced Interdisciplinary Research University of JinanJinan 250022ShandongChina State Key Laboratory of Crystal Materials Shandong UniversityJinan 250100ShandongChina Institute for Smart Materials&engineering University of JinanJinan 250022ShandongChina

High discharged energy density and excellent flexible properties in dielectric materials are significantly sought to meet the rapid advancements in the electronics industry. In this study, covalent bonds are constructed between poly(vinylidene fluoride-chlorotrifluoroethylene), which contains olefinic bonds, and thiol-modified BaTiO_(3) at the interface before the nanocomposite films are fabricated. The presence of the covalent bonds is proved to promote the dispersibility of the modified BaTiO_(3) and enhance the interfacial adhesion between the modified BaTiO_(3) and the polymer, followed by a remarkably positive effect in suppressing the dielectric loss(tanδ) and increasing the breakdown strength(Eb) of the nanocomposite films. In addition, the cross-linking treatment in the preparation process is found to be favourable for improving the mechanical properties of the nanocomposite films, which benefits the enhancement of Eb. Furthermore, at 400% elongation, the stretched nanocomposite film doped with 5 vol% modified BaTiO_(3) exhibits an Eb15.6% greater than that of the unstretched film, and the discharged energy density reaches 11.4 J/cm^(3) with a high discharge energy efficiency of 84.5%. This study provides a novel strategy for preparing flexible nanocomposites with powerful interfacial adhesion at high filler content to achieve high discharged energy density.

BACKGROUND Tamarix chinensis Lour(TCL)is a shrub that usually grows in arid or semiarid desert areas and saline-alkali *** is a traditional Chinese herbal medicine with hepatoprotective,antioxidant,antibacterial,and antitumor *** To investigate the possible protective effects of TCL against liver injury induced by chronic ethanol *** C57BL/6J male mice were fed a Lieber-DeCarli lipid diet containing alcohol and received(by gavage)a water-alcohol extract(80%)of TCL(100 and 200 mg/kg BW)or distilled water for 4 *** euthanasia,liver tissues were observed histologically with hematoxylin and eosin staining and Oil red O staining,and the levels of alanine aminotransferase,aspartate transaminase,hepatic lipids,reactive oxygen species,malondialdehyde,and superoxide dismutase were *** addition,expression of the NOD-like receptor family,pyrin domain-containing 3(NLRP3)inflammasome and downstream proinflammatory cytokines were *** Compared with the ethanol group,mice in the TCL-treated group(200 mg/kg)had significantly lower serum levels of alanine aminotransferase(mean,34.1 IU/L vs 45.3 IU/L,P<0.01)and aspartate transaminase(mean,89.6 IU/L vs 115.7 IU/L,P<0.01),as well as marked reduction of hepatic tissue reactive oxygen species(decreased by 27.5%,P<0.01)and malondialdehyde(decreased by 76.6%,P<0.01)levels,with a significant increase of superoxide dismutase(Increased by 73.2%,P<0.01).Expression of the NLRP3 inflammasome and its downstream cytokines[interleukin(IL)-1β,tumor necrosis factor-α,and IL-6],and recruitment of natural killer T cells to the liver,were reduced in the TCLtreated incubation with a Lieber-DeCaril ethanol lipid diet *** These findings suggest that a TCL extract(200 mg/kg)protects against chronic ethanol-induced liver injury,probably by inhibiting the NLRP3-caspase-1-IL-1βsignaling pathway and suppressing oxidative stress.
