Abstract: This invention discloses a transparent standalone resin or masterbatch concentrate composition and manufacturing method of transforming commercial transparent grade base thermoplastics into anti-biofouling resins through extrusion or any similar hot melt mixing processes. The re-compound solids enable a number of product reforming processes, including but not limited to thermoforming, profile extrusion, injection molding, blow molding, blow filming, film casting, and spinning into articles of different shapes and geometries or overmolding on plastic substrates that can resist surface adsorption of microbes, mammalian cells, proteins, peptides, nucleic acids, steroids and other cellular constituents after solidification. The articles formed thereof additionally exhibit mechanical reinforcement and no leaching while retain the optical clarity of the base thermoplastics in the same product form as quantified in terms of the light transmittance and haze.
