The invention provides to a powdered composition of additives and a method of use thereof for increasing the visibility, potency and coverage of disinfectant solutions, such as bleach.

Antimicrobial coatings that are transparent and not easily stained are disclosed. Some variations provide a transparent antimicrobial structure comprising: a discrete solid structural phase comprising a solid structural polymer with a glass-transition temperature from 25° C. to 300° C.; a continuous transport phase interspersed within the discrete solid structural phase, wherein the continuous transport phase comprises a solid transport material; and an antimicrobial agent contained within the continuous transport phase, wherein the antimicrobial agent is dissolved in a fluid and/or in a solid solution with the continuous transport phase. The discrete solid structural phase and the continuous transport phase are separated by an average phase-separation length selected from 100 nanometers to 500 microns. This invention resolves the trade-off between antifouling and fluorinated material content. This invention also resolves the trade-off between transport of absorbed molecules and transparency. The result is an improved antimicrobial structure that is both antifouling and transparent.
