“…3 The porous morphology depends on several variables such as the porogen and crosslinker used in feed, or the previous thermal history of the sample. [3][4][5][6][7][8][9][10][11][12] Sponges and macroporous polymers are prepared with porogen agents 9,10 or other porogenic methods. 4,11,13,14 Polymer networks synthesized without using porogens, exhibit pores (inherent porosity 12 ) that in the swollen state are filled with solvent and contribute significantly to the degree of swelling.…”

“…1,2 Polymer morphology is also known to have an important incidence on the hydrogel properties. [3][4][5][6][7] Crosslinked polymers may show pores with quite different size (from nanometer to millimeter diameters), structure (closed or interconnected) and shape (fibrillar networks, honeycomb-like, spherical, cylindrical, channel-like). 3 The porous morphology depends on several variables such as the porogen and crosslinker used in feed, or the previous thermal history of the sample.…”

“…The pore size of CM-b-CD hydrogel was larger and the texture was looser. The factors controlling the structures are known to be the ratio of cross-linker to monomer and their concentrations in the reaction mixture [28]. Two factors were kept constant in preparing two kinds of hydrogels.…”
