In this study, PVA/TA hydrogel films were fabricated using the solution casting method. To enhance mechanical properties and antibacterial activity, citric acid was employed as a green crosslinking agent, and TiO2 nanoparticles were incorporated. SEM images showed the formation of a porous structure with interconnected pores, which facilitated water and steam penetration. FTIR studies confirmed the interaction between PVA, CA, and TA. The addition of TiO2 significantly improved the water vapor transmission rate. Increasing the amount of CA and TA led to increased crosslinking, resulting in reduced swelling, degradation and hydrophilicity. The results of mechanical investigations showed an increase in the tensile strength with increasing CA and TA content and an increase in stiffness with increasing CA and decreasing TA content. Furthermore, the addition of TiO2 up to 1 wt % further improved the mechanical properties. These findings indicate the potential of PVA/TA/TiO2 hydrogel for biomedical applications, especially in wound dressings.
