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.

Antimicrobial polysiloxane materials containing metal species

Functionalized cross-linked polysiloxanes, such as quaternary ammonium terminated cross-linked polyalkylsiloxanes are described herein. The functionalized cross-linked polysiloxanes may be used in an antifouling composition to prevent biological fouling in aqueous and/or marine environments.

Quaternary ammonium functionalized cross-linked polyalkylsiloxanes with anti-fouling activity

A polymeric material may be prepared by reacting a composition that includes polyol, polyisocyanate, and polyorganosiloxane having functional groups capable of reacting with the polyisocyanate, wherein the polymeric material has a surface which includes raised microdomains.
