		abstract={Carboxymethyl Cellulose (CMC)/polyvinyl alcohol (PVA) films were prepared by
crosslinking method. The films were chemically crosslinked with citric acid (CA) for
tuning their properties. The formation of CMC/PVA/CA films was confirmed using
X-ray diffraction, FT-IR spectroscopy and scanning electron microscopy. In
addition, the films were tested for antibacterial activities. The results indicate that
the hydrogen bond interactions between CMC/PVA and CA can be formed. The films
demonstrated excellent antibacterial effects against E. coli and S. aureus. The
addition of CA can efficiently improve the water absorbtion of the films. Moreover,
the films present three-dimensional structure, porous networks and low toxicity.
Therefore, the developed CMC/PVA/CA film can be well-suited for biomedical
application.}
