| Summary: | The increasing amount of paper wastes generated around the world has caused disposal problems to
our environment. Paper wastes are one of major cellulosic waste materials which include printed office
papers, newspapers, magazines and books. In this study, cellulose was extracted from printed paper
waste and then converted into cellulose nanoparticles and nanocomposite films. The paper wastes
underwent pretreatment, dissolution and regeneration processes under controlled conditions. The
nanoprecipitation technique was used to regenerate cellulose nanoparticles from dissolved cellulose
solution. Particle sizes of cellulose nanoparticles were controlled by varying parameters such as
cellulose concentration and addition of surfactant. The sago starch and cellulose nanoparticles were
used to form green nanocomposite film. Both cellulose nanoparticles and nanocomposite films
prepared from printed paper wastes were characterized by SEM and FTIR. |
