In this approach, low dielectric loss and high dielectric constant may be made possible by ternary composites that use metal alloy components as reinforcing fillers. Here, Cu-based alloy was added to acrylonitrile-butadiene rubber (NBR) to produce ternary rubber composites. Unfortunately, the Cu–Al–Zn alloy’s material incompatibility with the rubber matrix typically leads to phase separation, void formation, and particle aggregation, all of which have a dramatic negative impact on performance. Using 3-(trimethoxysilyl)propyl methacrylate as a coupling agent, Cu–Al–Zn alloy particles were uniformly dispersed onto the NBR rubber matrix through surface modification. By using scanning electron microscopy, the appropriate reinforcement of modified Cu-based alloy particles into NBR was carefully examined. The effect of modified Cu–Al–Zn alloy loading on the swelling behavior of the composite was also investigated. The findings show that the shape and dispersion state of modified Cu–Al–Zn alloy were important for the dielectric characteristics of the NBR compounds. By adding reinforced modified Cu-based alloy to the NBR matrix, mechanical characteristics were significantly improved. The uniform dispersion of modified Cu–Al–Zn alloy particles and strong interfacial compatibility with rubber matrix are the reasons for the outstanding performance of NBR composites, which suggests high-performance dielectric composite.</p></div>","PeriodicalId":737,"journal":{"name":"Polymer Bulletin","volume":"81 16","pages":"15207 - 15234"},"PeriodicalIF":3.1,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00289-024-05392-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141784521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CuO is synthesized by colloidal sol–gel method using oxalic acid as capping agent to obtained desired morphology.

The XRD revealed that nanoparticles are extremely crystalline, but nanocomposite is amorphous because of the presence of polymer.

FTIR spectra of CuO showed bending vibration, while CuO/PANI showed the presence of benzenoid and quinoid rings. Catalytic productivity of the CuO and CuO/PANI as catalysts in degradation of dyes and reduction of nitro compounds is also studied. The degradation and reduction processes are monitored through the utilization of UV–Vis spectrophotometer. The catalytic activity of both catalysts is evaluated by several parameters including k<sub>app</sub>, degradation/reduction time, % degradation/reduction, degraded/reduced concentration and half-life. Among all substrates, highest k<sub>app</sub> is 0.0653 min<sup>−1</sup> for CV by CuO, while 0.0502 min<sup>−1</sup> for EBT by CuO/PANI due to large surface area.

This paper examines the possibility of using nano-chitin and chitosan as effective and sustainable adsorbents for the removal of PPCPs from wastewater. The recent progress in functionalized nano-chitin or chitosan composites is reviewed with attention to enhanced adsorption capacity and selectivity toward different classes of PPCPs. Unique features of nano-chitin and chitosan, such as their large surface areas and biocompatibility making them a good choice for PPCP adsorption, are also discussed. Critical evaluation is given about how these nanomaterials absorb PPCPs by looking at various mechanisms like electrostatic interactions, hydrogen bonding, hydrophobic interaction, among others.
