摘要:
Articles having an exterior surface comprising an inorganic biocidal agent and a first thermoplastic resin can provide a good combination of biocidal activity and physical properties. The biocidal activity may be enhanced by thermoforming an article or multi-layered article into a shaped article having the desired level of biocidal activity.

Disclosed herein are thermoformable sheets, methods of making 3D articles, and articles made therefrom. In one embodiment, a method for making a 3D article comprises: heating a sheet to form a heated sheet, blowing the heated sheet to form a bubble, disposing a mold in the bubble, and vacuum forming the heated sheet to the mold to form the 3D article. The sheet has a surface layer comprising a polycarbonate-polysiloxane copolymer, and the surface layer contacts the mold.
