Abstract :Abstract: In this study, St. John\\\'s Wort oil was obtained by maceration, a tradi-tional method, using olive oil macerate. St. John\\\'s Wort oil was added to chi-tosan-based biofilms as an additive, and chitosan-based biofilms containing chi-tosan/St. John\\\'s Wort oil (SJWO) were obtained. Biofilms were characterized by FTIR. The preparation and physical potential use of these films are presented. The porosity, swelling capacity, thickness, degradation rates, pore volumes and opacity of biofilms were determined. It was observed that as the amount of oil entering the structure increased, the thickness of the film increased and its swelling properties decreased. The thickness and opacity of CN/SJW-0.2, CN/SJW-0.6 and CN/SJW-0.8 biofilms were determined as 0.17, 0.28 and 0.30 mm and 1.21, 0.98 and 0.94, respectively. It was determined that increasing the amount of SJWO in-creased the film thickness and decreased its opacity. The pore volume (Vp) values of CN/SJW-0.2, CN/SJW-0.6, and CN/SJW-0.8 were calculated as 0.098, 0.0085 and 0.0086. The porosity values of the films CN/SJW-0.2, CN/SJW-0.6 and CN/SJW-0.8 were determined as 0.01952, 0.00172 and 0.00175 re-spectively.
