Abstract
An antimicrobial composition is disclosed. The antimicrobial coating composition includes at least one cured phase change ink which may include one or more crosslinked polymers, a photoinitiator, a wax, a gellant, and an antimicrobial additive. The composition also includes an engineered surface topography formed by the cured phase change ink. A method of preparing a textured antimicrobial surface is also disclosed. The method may include designing a template having a texture, printing the template onto a substrate using an uncured antimicrobial ink, and providing a light source to crosslink the uncured antimicrobial ink.
Claims17
An antimicrobial coating, comprising:
- a cured phase change ink comprising:
- a crosslinked polymer;
- a photoinitiator;
- a wax;
- a gellant;
- and
- an antimicrobial additive;
- and
- wherein a surface topography formed by the cured phase change ink comprises protruding features having a height from about 10 to about 5000 nm and spaced apart from one another by about 1 nm to about 5000 nm.
An antimicrobial coating, comprising:
- a crosslinked polymer;
- an antimicrobial additive;
- and
- wherein a surface topography of the antimicrobial coating comprises protruding features having a height from about 10 to about 5000 nm and spaced apart from one another by about 1 nm to about 5000 nm.
A method of preparing a textured antimicrobial surface, comprising:
- designing a template comprising a texture;
- printing the template onto a substrate using an uncured antimicrobial ink;
- and
- providing a light source to crosslink the uncured antimicrobial ink;
- and
- wherein the texture comprises protruding features having a height from about 10 to about 5000 nm and spaced apart from one another by about 1 nm to about 5000 nm.
