Claim 13:
14. An automotive vehicle interior panel comprising:
a flexible exterior surface comprising an antiviral material, wherein the antiviral material is powder and the flexible exterior surface is formed by molding with the powder;
a rigid substrate; and
a compressible foam disposed between the flexible exterior surface and the rigid substrate,
wherein the antiviral material comprises a polymeric matrix, and graphene particles dispersed within the polymeric matrix at a concentration of greater than or equal to about 0.05 wt. % to less than or equal to about 10 wt. % based on the total weight of the antiviral material, and
