Abstract
Polysiloxane-based materials, which include metal species, are provided. The polysiloxane-based compositions and materials generally include (i) amino-functional polysiloxane material and (ii) a plurality of metal species distributed within the polymeric material. Polymer based compositions in which the amino-functional polysiloxane material includes quaternary ammonium groups, e.g., tetraalkyl ammonium groups, are examples of suitable materials which may be used to form the present compositions. The metal species, which may be in an oxidized and/or neutral state, may be bonded, coordinated, chelated, suspended, and/or dispersed within the polymeric material.
