Abstract in another language

Photoresponsive superabsorber particles containing a crosslinked hydrophilic core and a hydrophobic azobenzene-containing shell were used to prepare photoresponsive polymeric nanomats, thus combining photoresponsivity with high porosity, toughness, and hydrophilicity. The properties of the nanomat composites were highly dependent upon the amount of the superabsorber photochromic particles added. Stable, highly elastic composite nanomats with very high loading (up to approximate to 50 wt.-%), good water absorption capacity (4000%) and relatively good tensile strength (3 MPa) were obtained. The photoresponsive behavior of the composites is demonstrated, which leads to relatively fast water desorption.
