Abstract
Properties of the chitosan films can be improved by incorporating clay minerals. So, solvent-cast films of the β-chitosan containing stevensite-rich or kaolinitic-illitic clays (up to 50 mass %) were characterized for their structural and mechanical properties. The effects of molecular weight (MW) and deacetylation degree (DD) of chitosan and the clay/chitosan mass ratio on the inhibition growth of Escherichia coli and Staphylococcus aureus were studied using the response surface methodology (RSM). The films consisted of exfoliated/intercalated or flocculated composites, and the electrostatic bonds formed between the functional moieties of the chitosan and the clay particles active sites essentially influenced their mechanical strength. The results of the study using RSM showed that the optimal value of MW required for the inhibition of the bacteria varied according to the film used, and high antibacterial activity necessitated high DD (89–97%).

期刊介绍：
Polymers from Renewable Resources, launched in 2010, publishes leading peer reviewed research that is focused on the development of renewable polymers and their application in the production of industrial, consumer, and medical products. The progressive decline of fossil resources, together with the ongoing increases in oil prices, has initiated an increase in the search for alternatives based on renewable resources for the production of energy. The prevalence of petroleum and carbon based chemistry for the production of organic chemical goods has generated a variety of initiatives aimed at replacing fossil sources with renewable counterparts. In particular, major efforts are being conducted in polymer science and technology to prepare macromolecular materials based on renewable resources. Also gaining momentum is the utilisation of vegetable biomass either by the separation of its components and their development or after suitable chemical modification. This journal is a valuable addition to academic, research and industrial libraries, research institutions dealing with the use of natural resources and materials science and industrial laboratories concerned with polymer science.
