Abstract:
Background: The spread of bacterial infections has become a growing concern
to human beings particularly in the medical and food packaging industry. Such infection
may also result due to the adhesion of microbes from the environment. Polyvinyl chloride
is a versatile polymer used in medical devices and food packaging materials, need to be
modified to enhance antibacterial activity.
Objective: The main focus of the present work was to prepare polymer nanocomposite
based on polyvinylchloride to prevent bacterial infections.
Method: Polyvinyl chloride/Polyester/bentonite clay composite films were prepared using
the solution casting method. The morphological properties of synthesized nanocomposite
films were studied using XRD, SEM, and AFM, whereas biological activity is evaluated by
bacterial adhesion study.
Results: The results showed that intercalation of clay present in nanocomposite films and
SEM analysis showed agglomeration of clay material due to high filler loading. The antibacterial
adhesion study showed the antibacterial activity of polymer nanocomposite films,
which is further confirmed by surface roughness values by AFM study.
Conclusion: Our result showed that such polymer nanocomposite films were useful in
medical and food packaging applications.
