Journal de Physique, 1988 The adsorption of uncharged polymers is, due to numerous efforts over past decades, fairly well understood. Some insight exists into the structure of the adsorbed layer, and the effect of the important parameters molecular weight, solvency and polymer/surface interaction has been investigated. Theory and experiment are beginning to converge.

Unusual Swelling Behavior of Hydrogels Modified with Spiropyran as Appendage or Crosslinker
Advanced Functional Materials, EarlyView.Not so innocent after all—spiropyran crosslinkers in methylenebisacrylamide‐crosslinked poly(acrylamide‐co‐acrylic acid) hydrogels increase crosslinking density, but also, counterintuitively, increase swelling. Charge complexation, cooperative chemo‐mechanical effects, and aggregation may explain these observations.
