healing of acute traumas which happened more frequently in people’s
daily life. Considering the convenience and portability in the
practical applications, the dry form of BC film was preferred to
the wet one. Hence, in this paper, a kind of BC dry film with
antimicrobial properties was developed by using benzalkonium
chloride as the antimicrobial agent. Benzalkonium chloride is a
sort of antimicrobial cationic surfactant, which was widely used in
commercial wound dressings and had a strong role against Grampositive
bacteria (Elder, 1989). Some properties of BC dry film
including swelling ratio, slow release of benzalkonium chloride
and antimicrobial effect were investigated in order to achieve good
performances in acute traumas treatment for the future.
