AB  - Preparation and morphological characterization of some novel hydrogels based on 
      chitosan (CS) with porous structure tailored by ice-templating and porogen 
      leaching are presented in the paper. Poly(methylmethacrylate) (PMMA), as 
      fractionated particles, has been used as polymer porogen. The influence of the 
      mesh of the fractionated PMMA particles, the weight ratio between CS and 
      fractionated PMMA particles, and the speed of the crystallization, on the 
      internal morphology of the hydrogels have been deeply investigated. The 
      morphology of the obtained hydrogels was observed by scanning electron microscopy 
      (SEM). As a function of the synthesis conditions, hydrogels with a heterogeneous 
      morphology consisting of randomly and evenly distributed polyhedral pores, or 
      with an oriented structure, which has microchanneled structures arranged along 
      the freezing direction, were generated.
