Abstract
Cellulose has a potential to become a key resource in the development of biodegradable film composites. In this work, cellulose was modified by using 2-(Trifluromethyl)benzoylchloride by base-catalyzed reaction. Modification of cellulose was confirmed by IR studies. The biodegradable composite films were developed by film casting method using modified cellulose with Poly(vinyl alcohol) in different compositions. The film composites were characterized by mechanical, moisture absorption, gas barrier, and biodegradable properties. Obtained films have shown transparency and flexibility and displayed good mechanical properties. Film composites also showed good biodegradability. Better barrier properties showed by film composites as the percentage of modified cellulose increased. This indicates the importance of modified cellulose as a reinforcing agent. After evaluating these properties of film composites, we came to conclusion that these biocomposites can be used to membrane and packaging applications.

Summary
Cellulose-based composites have come to the attention of researchers becauseof the numerous advantages which these renewable fibres represent. Cellulose is considered to be one of the most promising renewable resources and an environmentally friendly [1,2,3,4] alternative to products derived from the petrochemical industry. Plant-derived cellulose has been widely used as either reinforcement. Modified cellulose has been used as reinforcements for various composites due to its excellent mechanical performance and fully biodegradable in a wide variety of environmental conditions. Chemical modification of cellulose [5,6,7,8] is an important route for the production of multifunctional materials
