"DESIGN, SYNTHESIS AND ANTIMICROBIAL PROPERTIES OF CELLULOSE BASED AMINE FILM",

Film directing toward applications in food packaging and counter top coating with
ability of inhibiting antimicrobial growth is important for maintaining food freshness
and reducing bacteria transmittance. In this work, cellulose-based fatty amine
with antimicrobial functionality covalently attached to cellulose backbone was synthesized.
The synthesis was performed in a three-step process that involves cellulose
oxidation, amination of oxidized cellulose using fatty amine and reduction. Films
composites with various proportions of cellulose-based amine and cellulose triacetate
were prepared. The films morphologies, tensile strengths, percent of elongation
and contact angle were evaluated. The cellulose-based amine showed excellent
antimicrobial activity against gram positive and moderate activity toward gram-negative
bacteria. The films prevented the growth of gram-positive bacteria by 99.99%.
Results indicate a good mechanical properties and bioactivities of produced film
which makes it suitable for use in food wrapping application.
