How the Crosslinker Amount Influences the Final Properties of Hydroxyethyl Methacrylate Cryogels.

ABSTRACT: The investigation of the mechanical, thermal, and adsorption properties of hydroxyethyl methacrylate (HEMA) cryogels as a function of a reactant ratio is herein reported to better address materials for specific applications. To this aim, cryogels have been synthesized using different monomer/crosslinker (N,N'-methylene-bisacrylamide-MBAA) ratios. The study of SEM images made it possible to identify the trend in the material's macroporosity. As would be expected, the average measured pore width decreased as the amount of MBAA increased while the number of pores grew. Swelling capacity ranges from 8.7 gW/g_gel (grams of water per gram of gel) to 9.3 gW/g_gel. These values are strictly connected with the pore's size and distribution, revealing that the water uptake for the
