| Abstract | Sodium alginate (SA) films were prepared by casting from methanol (MeOH) solutions and their tensile properties, like tensile strength (TS) and elongation at break (Eb %), were monitored. The resulting films of SA were photocured with vinyltriethoxysilane [H2C=CH-Si-(OC2H5)(3)] in order to improve the tensile properties. Several acrylic monomers of different functionalities as additives (2%), like ethyl acrylate (EA), 2-hydroxyethyl acrylate (2-HEA), and tripropylene glycol diacrylate (TPGDA), were incorporated with silane with the aid of UV radiation. Further analyses of the prepared films were characterized by Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA) and a TS test. FTIR studies indicate that there are intermolecular hydrogen bonding interactions, i.e., -OH center dot center dot center dot center dot center dot O=C in silane/SA blends. This blend films also exhibited the higher thermal stability and improved the tensile properties of the films. Degradation of SA by UV spectrometry induces time-dependent degradation. |
