Abstract :The main purpose of this study is to obtain a renewable natural biocomposite film with the sour cherry kernel (SCK), a natural waste. Biobased acrylated epoxidized soybean oil (AESO) resin was used as a composite matrix. The effect of additive ratio on antibacterial activity tests, swelling-solubility-water content, and pH properties of the obtained AESO/SCK composite films were investigated. In addition, the surface morphologies of the film samples were examined by SEM. It has been observed that AESO/SCK films have antibacterial properties. In addition, the swelling ratio of AESO/SCK composite films was found to be between 0.2433% and 4.6343%. The water solubility rate of AESO was determined as 0.1103% by weight. This ratio increased as the SCK ratio increased and reached 0.7380% with a 50% SCK ratio. The water content of AESO/SCK composite films was in the range of 0.660-2.1203%. The pH of all prepared biocomposite films was between 7.18-7.33 after 72 hours, and these values were found to be compatible with skin pH. The water vapor permeability of AESO was measured as 1.382x10-07 g.m/(m2*Pa*s) on average. With 50% SCK by weight, this value decreased to 5.025x10-10 g.m/(m2*Pa*s).Keywords : Antibakteriyel aktivite, Biyokompozit film, Vişne çekirdeği içi.
