Abstract

In recent years, there has been a considerable attention on producing and using renewable and environmental friendly cellulose film and coatings. In respect to the application of these films and coatings in different industries such as food, packaging and medical industries, the antimicrobial property such films and coating is an important issue. . The purpose of this research has been the production of cellulose based antibacterial film. First, long fiber pulp was converted to NFC using a supergrinder and then nanosilver treated films were prepared applying silver nitrate using two different methods. In the first method, silver nanoparticles at either 5 and 10 ppm dosage were reduced on NFC particles’ surface using retention aid. In second method the prepared NFC film was immersed in a solution of silver nanoparticle having the concentration levels of 5 and 10 ppm. At higher concentration of nanosilver solution, the retention Ag nanoparticle in the first method was higher than the second method whereas, at lower concentration, the differences of retained nanosilver between two methods was not extensive. It worth to mention that immersion method shows the benefit of avoiding Ag nanoparticle to be drained during pulp dewatering and nanosilver solutions could besimply reused.
