The obtained nanoparticles are characterized with XRD and the crystallite size is calculated using Scherrer’s formula, ranging between 16 and 22 nm, with spherical morphology observance using FESEM.

Among filler-loaded composites, 1.5 wt% of NiCo<sub>2</sub>O<sub>4</sub> nanoparticles/ 5 wt% wood sawdust reinforced Epoxy/Kevlar composites show a superior tensile strength of 61.9 MPa that signifies the strong filler-matrix bonding and less porosity. High thermal stability is observed for 1.5 wt% of NiCo<sub>2</sub>O<sub>4</sub> nanoparticles/ 5 wt% wood sawdust reinforced Epoxy/Kevlar composites, wherein, an increase in weight loss of the filler-loaded composite implies better thermal conductivity of the matrix system for different filler loading.

Shuttling of polysulfides during charge-discharge cycles, volume expansion of sulfur cathode during redox reaction, and insulating behavior of sulfur are some of the prime inherent limitations of lithium - sulfur (Li-S) technology. These drawbacks adversely affect the commercialization of Li-S batteries. Present work is focused on developing self-stabilized dispersion polymerized(SSDP)aniline (PANI)-carbon nanotubes (CNT) based, flexible, and free-standing interlayer, called PCNT, to be inserted between the cathode and separator to block polysulfide shuttling effect, along with sulfur cathode, modified using PANI coated activated carbon, termed as PACS. PANI with high conductivity around 1000 Scm<sup>− 1</sup> is used for making PCNT interlayer films. Modified sulfur cathode PACS, obtained by in situ polymerization followed by the solvothermal method can facilitate effective charge transfer due to the high electrical conductivity of PANI and provides enough surface area to cope with the volume expansion of sulfur cathode due to the porous structure of activated carbon. Li-S cells assembled using PACS cathode with the PCNT interlayer show an initial discharge capacity of 1141.26 mAh g<sup>− 1</sup> at 0.1 C and excellent cycling stability. Surface modification of the sulfur cathode, achieved through composite formation and the use of PACS, along with the incorporation of PCNT interlayer, represent a promising approach for designing next-generation Li-S cells with significantly improved capacity, energy density, and cycling stability.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":639,"journal":{"name":"Journal of Inorganic and Organometallic Polymers and Materials","volume":"35 3","pages":"1808 - 1818"},"PeriodicalIF":3.9,"publicationDate":"2024-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143801260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compressive strength measurements were performed to evaluate the mechanical properties of the geopolymers studied. At the same time, their efficiency in removing crystal violet (CV) dye was tested by applying batch-mode adsorption as a water treatment technique. The structural and microstructural properties of the aluminosilicate precursors used and their derived geopolymer samples were characterized by several physicochemical analysis techniques. Mechanical tests highlighted that the fly ash-based geopolymer (FA-GP) possessed approximately twice the compressive strength of the metakaolin-based geopolymer (MK-GP). In contrast, tests of the adsorbents’ efficiency in removing the CV dye from an aqueous medium revealed that MK-GP removed the dye somewhat more effectively than FA-GP. The findings of the analytical characterization pointed to the formation of a sodium aluminosilicate hydrate gel as the principal binder phase in both geopolymer matrices. Microstructural and textural properties explained the difference in mechanical and adsorption performance between the two geopolymers, as both matrices were mainly formed of an amorphous geopolymer gel with a different meso-type porous nature for FA-GP, in contrast to MK-GP, which is characterized by larger pore sizes. The kinetic and isothermal readings for CV-dye adsorption by MK-GP and FA-GP fit well, respectively, with the pseudo-second-order, Langmuir, and Temkin models.
