Chitosan (CS) as the only polycation coming from renewable resources is endowed with
intrinsic valuable properties, such as: biocompatibility, biodegradability, low cost, easy
availability, and high reactivity due to plenty of the reactive functional groups (-NH 2 and–
OH). Therefore, CS and its derivatives have been involved in numerous applications, either
alone or as components in composite materials. This review aims to present an overview on
the most recently published information on the preparation of porous CS based composite …
