dc.description.abstractThe process called “polydopamine-dip coating” was successfully applied to modify the surface of poly(2-hydroxyethyl methacrylate), PHEMA, cryogel disks for the first time. This facile surface modification process fitted very well to the chemistry of cryogels since the integrity of the cryogel disks was maintained during the whole process. Polydopamine (PDA) nanocoating process was observed to be homogeneously performed through the pores and there was a net color change from white to brown after 24 h. The obtained (brownish) material (PHEMA-PDA) was characterized with respect to FTIR spectroscopy, pHpzc, and water-holding capacity analyses. The potential of this new material was studied by utilizing it as an adsorbent for the adsorption of Ni(II) from synthetic aqueous solutions. The equilibrium adsorption data were analyzed on the basis of the Langmuir, the Freundlich, and the Temkin isotherm models. In general, Ni(II) adsorption on PHEMA-PDA was evaluated as a favorable process as depicted from the studied models. The proposed approach was found to be a promising post- surface modification process for tailoring the surface of monolithic cryogels without any difficult synthesis steps and harsh chemicals.
