摘要： An antimicrobial plastic composition suitable for any non-foamed application includes an antimicrobial compound uniformly dispersed in a plastic. The antimicrobial compound is selected from the group consisting of silanol quaternary ammonium compounds and salts thereof (SQACs) having a hydroxyl or hydrolyzable silane group capable of undergoing a condensation polymerization reaction to form a homo or copolymer, and/or forming a covalent bond with the plastic and/or other components in the plastic composition. Also described are methods for preparing an antimicrobial plastic composition including: (i) uniformly dispersing an antimicrobial compound in a plastic; (ii) forming a shaped article; and (iii) optionally exposing the shaped article obtained in (ii) to moisture or steam. The antimicrobial plastic composition can provide an article which is non-leaching, environmentally safe, non-toxic, with surface renewability, durable antimicrobial properties and also has improved physical and chemical properties such as tensile strength, static dissipation and chemical resistance.
