ZnO nanoparticles were uniformly distributed in GC/PEG matrix
to form GC/PEG/ZnO nanocomposites. GC/PEG/ZnO nanocomposites
showed the higher swelling ratios as the pH decreased to
acidic condition. The presence of ZnO in GC/PEG matrix inhibited
the proliferation of bacteria effectively. The antimicrobial activity
of GC/PEG/ZnO nanocomposites increased as the content of
ZnO increased. The antibacterial activity was improved more effectively
by doping ZnO with small amount of Ag nanoparticles.
GC/PEG/ZnO/Ag nanocomposites could be applied successfully as
the antibacterial wound-dressing films based on both swelling and
antibacterial characteristics.
