Preparation and Characterization of Crosslinking Monomers Grafted Gelatin Films by Photocuring
نویسندگان
چکیده
Thin films of were prepared by casting and its tensile properties like tensile strength (TS) and elongation at break (Eb%) were studied. The gelatin films were procured with two types of monomers such as 5% ethylene glycol (EG) and 5% ethylene glycol dimethacrylate (EGDMA) to increase the tensile properties. Five percent of monomer solutions were prepared in MeOH along with 2% photoinitiator; Irgacure-651. Soaking time and UV-radiation intensities were optimized with extent of polymer loading (PL) and tensile properties of the cured films. Comparing the properties of EG and EGDMA treated gelatin film, EG showed the best performance. The EG-cured gelatin film with 5 min soaking time showed the highest tensile strength 47.3 MPa and elongation at break 28.4%. The water uptake was determined for raw film 500.13%, EG grafted gelatin film 375.34% and EGDMA grafted film 412.87%.

The effects of zinc oxide nanorod on the barrier, sorption isotherm and antibacterial properties of tapioca starch/bovine gelatin Bionanocomposite films were investigated. The nanorod-rich ZnO (ZnO-N) was homogenized by sonication and incorporated into tapioca starch/bovine gelatin solutions at different concentrations (e.g. 0.5, 2, and 3.5% w/w dried solid). Incorporation of 3.5% of nanopartic...
