Tensile strength (TS) and tensile modulus (TM) of chitosan films were found to be 30 MPa and 450 MPa, respectively. Silane monomer (3-aminopropyl tri-methoxysilane) (0.25%, w/w) was added into the chitosan solution (1%, w/w) and films were casted. Then films were exposed to gamma radiation (5-25 kGy) and mechanical properties were investigated. It was found that at 10 kGy, the values of TS and TM were improved significantly. Silane grafted chitosan film reinforced poly(caprolactone) (PCL)-based tri-layer composites were prepared by compression molding. Silane improved interfacial adhesion between chitosan and PCL in composites. Surface of the films was investigated by scanning electron microscope (SEM) and found better morphology for silane grafted films. %G English %2 https://riip.hal.science/pasteur-01005560/document %2 https://riip.hal.science/pasteur-01005560/file/Lacroix_M_Rad_phys_chem_81_932-35.pdf %L pasteur-01005560 %U https://riip.hal.science/pasteur-01005560 %~ RIIP %~ INRS-IAF
