Abstract: Embodiments herein are related to hydrophilic open cell foams with particulate fillers. In an embodiment, an article is provided that has an open cell foam structure including a hydrophilic polymer and about 0.1 wt. % to about 40.0 wt. % of a particulate filler dispersed within the hydrophilic polymer. The open cell foam structure can exhibit a rate of absorption of water greater than an otherwise identical foam lacking the particulate filler. Other embodiments are included herein.
