The antimicrobial thin film coating is a polyelectrolyte complex film applied to a substrate, with the polyelectrolyte complex material having biocidal properties. The polyelectrolyte complex material is formed from a first polyelectrolyte material having a positive charge, which is applied to the substrate in the form of a solution, and a second polyelectrolyte material having a negative charge, which is applied to the substrate following application of the first material. The positively charged polyelectrolytes and the negatively charged polyelectrolytes arrange themselves into a polyelectrolyte complex, rather than an alternating multi-layer structure, due to the electrostatic attraction between particles, allowing for the formation of a thin film with optimal coverage of the substrate.
