Ice-templated hydrogels based on chitosan with tailored porous morphology.

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… CONTINUE READING
