Abstract: Embodiments herein are related to hydrophilic open cell foams. In an embodiment, an article is included having an open cell foam structure. The open cell foam structure can include a hydrophilic polyurethane polymer comprising a reaction product of a polyol and/or polyamine component and an isocyanate, the polyol and/or polyamine component comprising a mixture of functionalized and non-functionalized polyols and/or polyamines in a ratio by weight of about 5:95 to about 95:5 of functionalized to non-functionalized.
