چکیده

In this paper, Chitosan-copper nanoparticles were successfully coated onto the Kraft paper
using a dip coating process. First, chitosan-copper nanoparticles solution was prepared by
reduction method and the use of ultrasonic radiation. It was employed copper sulphate pentahydrate
as precursor salt, NaOH as a reducing agent and Chitosan as capping agent to prepare
Chitosan-copper nanoparticles solution. The solution was analyzed by UV-Vis spectroscopy
and dynamic light scattering (DLS). After the coating process, the coated Kraft paper was characterized
by X-Ray diffraction and scanning electron microscopy (SEM). Then, the antimicrobial
activity of the Kraft paper, in contrast to Bacillus subtilis and Escherichia coli was measured
by disc diffusion method.
