    摘要: A method for forming an antimicrobial coating on a substrate is provided. The method comprises dissipating and entrapping (embedding) sulfonated copolymer particles in void spaces or interstices of fibers of a fabric forming an outer layer of a substrate. The sulfonated copolymer is selected from the group of perfluorosulfonic acid polymers such as sulfonated tetrafluoroethylene, polystyrene sulfonates, sulfonated block copolymers, polysulfones such as polyether sulfone, polyketones such as polyether ketone, sulfonated poly(arylene ether), and mixtures thereof. The fibers comprise a thermoplastic polymer having a melting point of less than 120°C, or 45-1 10°C, or 45-80°C. The sulfonated copolymer forms an antimicrobial coating layer for killing at least 90% microbes in the air within 30 minutes of contact with the coating.

    摘要: The present disclosure provides a method of enhancing the shelf-life of an activated surface of a thermoplastic material, including: coating at least a portion of a surface of the thermoplastic material with at least one adhesion promoter to provide a coated surface; and treating the coated surface with plasma to provide the activated surface of the thermoplastic material; wherein the activated surface has a contact angle in the range of from about 0 to about 40°; and wherein the presence of the at least one adhesion promoter is effective to maintain the contact angle in the range of from about 0 to about 40° for a time of about 10 days or greater.
