  • Patent number: 11136439
    Abstract: This disclosure discloses a preparing method of transforming commercial base thermoplastics into germ-repellent resins or functional masterbatch through plasma and (melt)mixing assisted grafting process. The resins or masterbatch concentrate composition 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 after solidification.
    Type: Grant
