  • The influence of the type of composition of PVA-chitosan blends on stability at elevated temperature

    Dane Badawcze
    open access

    The dataset shows the results of a visual evaluation of chitosan and polyvinyl alcohol composites. The composites were prepared by combining chitosan water solutions, dissolved in selected acids, and polyvinyl alcohol solution, freeze drying, and heating at 150°C dry composites. The results confirm that the chitosan / PVA composites, in which the first...

  • Surface modifcation of PMMA polymer detected by XPS

    Dane Badawcze
    open access

    In order to obtain the experimental specimens, four PMMA/PC61BM samples with the following  mass proportions were prepared: 10%, 20%, 30%, and 40%. In addition, as a reference, a PMMA sample without  PC61BM was prepared as well. For the fabrication process, PC61BM 99.5% (Solenne BV), chloroform HPLC  (Sigma Aldrich), and PMMA (commercially available...
