The increased presence of the modified clay in the host matrix of the PVDF/PMMA blend significantly influenced the melting temperature and the degree of crystallinity of the PVDF crystallites. The scattering of the dielectric spectra, which covers a wide range of frequencies from 20 Hz to 1 GHz, indicates the presence of the phenomenon of interfacial polarization associated with the dielectric capacitance complex at lower frequencies in these composites at 27 °C.

Crosslinking modification is one of the feasible methods to further improve their properties. To make use of the advantages of monomer precursor method over the polymer precursor method in forming dense interpenetrating networks, and then optimizing the surface structure of materials and providing more adsorption sites, the mesoporous cross-linked poly-o-phenylenediamine (M-CR-PoPD) prepared by using the former one and used in removing Cu2+ from aqueous solution. The FTIR results showed that the monomer was successfully crosslinked and polymerized. The loosely packed target product with a hierarchical pore structure distribution was successfully formed. The maximum adsorption capacity of 105.18 mg g−1 was obtained at 25 °C after 3 h of adsorption when M-CR-PoPD prepared at the reaction time of 6 h using anhydrous ethanol as solvent and trimethylolpropane-tris(3-aziridinyl) propionate as crosslinking agent. This value reached the optimum Cu2+ removal capability of reported PoPD-based adsorbents. According to EDX, FTIR, and XPS data before and after adsorption, the possible adsorption mechanism based on the cation-π interaction and the formation of Cu–N bonds was proposed.

Compared to traditional adsorbents, the magnetic sodium alginate hydrogel shows significantly improved adsorption capacity, particularly for Pb2+ ions. At pH ca. 4 and an adsorption time of 120 min, the hydrogel achieves a maximum adsorption capacity of 137 mg/g for Pb2+, with an adsorption rate of 83 %. The adsorption kinetics follow a pseudo-second-order equation, while thermodynamically, the process adheres to the Freundlich adsorption model, with capacity positively correlated with temperature and concentration. The negative ΔH value indicates an exothermic and spontaneous adsorption process. In competitive adsorption experiments, the hydrogel demonstrates strong selective adsorption towards Pb2+. It also exhibits excellent reusability, maintaining 80 % adsorption capacity after 10 cycles. The magnetic sodium alginate composite material possesses favorable recyclability and convenient magnetic separation properties, offering significant potential in various applications.","PeriodicalId":16881,"journal":{"name":"Journal of Polymer Engineering","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140600912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study provides an overview of ion substitution chemistry, highlighting the role of ions and how they affect the applicability of carrageenan. The characteristic of barium sulfate, which is widely used as radiopaque to provide contrast for diagnostic radiographic examinations in the gastrointestinal mucosa, is provided by its linkage with the barium ion despite K+’s natural binding with carrageenan. The additional role of the Ba ion linked carrageenan was found highly selective for cancer cell through the in vitro cell line assay; however, the nonattachability to the normal cell makes useful to trace and treat the cancer cell. The tracing is possible because of the barium sulfate functional group and its nanosize molecule, which shows precision medicine, fluorescence, and X-ray/CT imaging character, to be utilized as the diagnostic purpose, especially to tumor cell.

In the context of this study, one such natural filler under scrutiny is mango shell powder (MSP), a byproduct derived from mango processing. The central objective of this investigation is to assess the potential of MSP as a filler in flax-jute hybrid epoxy composites, with a keen focus on enhancing their properties. Specifically, the study aims to elucidate the impact of incorporating MSP filler on the mechanical and wear characteristics of these composites. The experimental approach involved the preparation of composite samples with varying weight percentages of MSP filler, ranging from 1 % to 9 % (1 %, 3 %, 5 %, 7 %, and 9 %), while maintaining a constant fiber and matrix weight ratio. The results obtained from the experiments revealed that composite samples containing a 7 % filler exhibited superior mechanical properties, while wear resistance demonstrated a noticeable decrease with the progressive increase in filler content. These findings suggest the potential efficacy of MSP as a filler in enhancing both the mechanical and wear characteristics of flax-jute hybrid epoxy composites, providing valuable insights for further applications in sustainable composite materials.","PeriodicalId":16881,"journal":{"name":"Journal of Polymer Engineering","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140154563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
