Abstract

Nowadays, the use of non-oil materials with desirable properties, and at the same time
reducing the adverse environmental impacts, has become one of the most important
issues in industry. Chitosan, as one of the most abundant biopolymers in nature, has
unique properties, including high biocompatibility, non-toxicity, acceptable antimicrobial
properties, and excellent performance in terms of film formation. These properties
have potentially made this biopolymer very useful in packaging industries, textile,
pharmaceutical, and papermaking. In this regard, the purpose of this study is to investigate
the effective parameters on the mechanical properties of chitosan biocomposites. The
parameters such as type, concentration, pH, and functional groups of solvents are taken
into consideration in making composites that are used as polymer phase fasteners. Also,
the effect of plasticizers on weight percentages to reduce the fragility of chitosan films is
discussed in this study. It was observed that the addition of each of these materials, due to
their structure and molecular weight, weight percentage, distribution pattern at the matrix
level, functional groups on their molecules affect the structure of chitosan polymeric chains
and can change the mechanical properties of a biocomposite.
