1 Introduction

Cellulose is the most abundant natural polymer on earth followed by chitosan While cellulose is a polysaccharide polymer consisting of D-anhydroglucose units joined together by 1 4-β glycosidic linkages [1] chitosan is a polysaccharide polymer composed of glucosamine and N-acetyl glucosamine units joint by 1 4-β glycosidic linkages [2] Both polymers have many advantages
