In this research, different polyanilines were synthesized by modifying synthesis methods and parameters in expectance to yield different properties, which may affect nickel removal efficiency. Besides, titanium dioxide and carboxymethyl cellulose were added to further improve Ni removal efficiency. All synthesized samples were examined with FTIR and UV–Vis to confirm their chemical structures and oxidation states. The electrical conductivities of the samples were measured on a four-point probe and their crystallographic information and incorporation of metal oxide were confirmed using XRD and EDX respectively. The samples’ thermal stability and morphologies were investigated using TGA and FESEM respectively. Among the different morphologies obtained, nanotubes showed highest Ni removal efficiency of 31.250% as its longitudinal structure allowed easier access of polyaniline active sites to interact with Ni ions. With the incorporation of TiO2 and carboxymethyl cellulose, the Ni removal efficiency of polyaniline/TiO2/carboxymethyl cellulose significantly improved to 66.8% with TiO2 improving the charge transport network and surface roughness while carboxymethyl cellulose provides additional active sites and improved hydrophilicity for the transfer of Ni ions from solution to adsorbent surface.","PeriodicalId":739,"journal":{"name":"Polymer Science, Series B","volume":"66 5","pages":"636 - 648"},"PeriodicalIF":1.0,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143668268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After that the base films were fabricated by casting of the mixture of polypropylene and polypropylene-g-N-phenylmaleimide, and then separators were obtained by stretching. Adoption of N-phenylmaleimide is a key technique to ensure separators with excellent heat resistance. It was also found that polypropylene-g-N-phenylmaleimide played an important role in improving the overall performance of those base films and separators. Compared with the polypropylene base film, the crystallinity, crystalline orientation, and elastic recovery of base films containing polypropylene-g-N-phenylmaleimide increased obviously. The prepared separators showed good pore structure and hydrophilicity. The heat shrinkage of separators measured at 130°C reduced from 18.8 to 10.6% while the content of polypropylene-g-N-phenylmaleimide increased from 0 to 10%. Coin cells assembled with separators also show higher battery capacity than the cells assembled with pure polypropylene separators.","PeriodicalId":739,"journal":{"name":"Polymer Science, Series B","volume":"66 5","pages":"592 - 602"},"PeriodicalIF":1.0,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143668282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its optical properties were measured by UV–Vis spectrophotometer, thermal analysis by Thermogravimetric Analysis (TG) device, morphological properties by scanning electron microscope (SEM) device, and crystallographic properties by X-ray Diffraction (XRD) device. Additionally, HOMO–LUMO band gaps were calculated by determining oxidation-reduction peak potential values with the Cyclic Voltammetry (CV) device. Since CuNPs@PSa shows very good antimicrobial properties against some yeasts and bacteria, its usability in drug release was investigated. For this, Ch–CuNPs@PSa encapsulation study was carried out by coating CuNPs@PSa with chitosan (Ch). Encapsulation efficiency, loading capacity, and in vitro release kinetics were calculated. As a result, it was observed that chitosan encapsulation increased the antimicrobial effect against bacteria and yeasts and achieved the release in a controlled manner. It has been determined that Ch–CuNPs@PSa can be used in drug delivery systems as it has an Encapsulation Efficiency (EE) of 98.70%, a Loading Capacity (LC) of 78.96% and a cumulative release of 98.84%. In this case, it can be said that the obtained Ch–CuNPs@PSa can be evaluated as effective in drug release studies.","PeriodicalId":739,"journal":{"name":"Polymer Science, Series B","volume":"66 5","pages":"649 - 661"},"PeriodicalIF":1.0,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143668335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pure Ppy is synthesized via chemical oxidative polymerization method, and a Ppy/TiO2–H100 composite is prepared with 10% TiO2–H100 by weight. The samples are characterized using Fourier Transform InfraRed spectroscopy (FTIR), X-ray Diffraction (XRD), Thermogravimetric analysis (TGA), and Scanning Electron Microscopy (SEM). The key finding is a significant structural change in Ppy upon the incorporation of TiO2–H100, as confirmed by XRD and SEM, which reveal enhanced crystallinity and a more compact morphology in composite. Regarding the electrical properties, conductivity measurements revealed that the electrical conductivity of pure Ppy at 300 K was 4.81 × 10–7 S/cm, whereas the Ppy/TiO2–H100 composite exhibited a higher conductivity of 5.08 × 10–7 S/cm, likely due to the interfacial interaction between TiO2–H100 and Ppy. Electrochemical impedance spectroscopy (EIS) results showed similar trends, where the composite exhibited semiconductor behavior, reflecting the influence of TiO2–H100 on the electrical properties. These results highlight the potential of TiO2–H100 to modify the electrical and structural properties of Ppy, making it a promising material for semiconductor applications.","PeriodicalId":739,"journal":{"name":"Polymer Science, Series B","volume":"66 5","pages":"662 - 672"},"PeriodicalIF":1.0,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143668334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
