Abstract :Active food packaging poly(vinyl alcohol)/boric acid/montmorillonite (PVA/BA/MMT) nanocomposite films incorporated with ferulic acid (FA) were synthesized using solution casting method. The structural, thermal, transmittance, antimicrobial, and antifungal properties of nanocomposite films have been investigated. The Fourier transforms infrared (FTIR) spectroscopy used to demonstrate the chemical structure of films and interaction between boric acid (BA) and PVA. X-Ray diffraction analysis (XRD) was performed to determine the dispersion and exfoliated of the montmorillonite in the PVA matrix. Thermal stability of PVA/BA/MMT films incorporated with FA were evaluated by using TG/DTA analyzer. Optical properties of films determined using by UV/VIS spectrophotometer at scanning percent transmittance. The antimicrobial an antifungal activity of the films incorporated with FA could inhibit bacterial growth. It has been determined that the nanocomposite films have antibacterial properties against E. coli and S. aureus and antifungal properties against C. albicans.
