Partially protonated and partially acylated poly(2-alkyl-2-oxazoline) antipathogen film apparatus and method of use thereof

Abstract

A method for treating a pathogen, comprising the steps of: removing, with an acid, less than 99% of —COR1 acyl groups from nitrogen sites of a poly(2-alkyl-2-oxazoline) in a solution to form a partially protonated and partially acylated poly(2-alkyl-2-oxazoline), where R1 comprises an alkyl group; adjusting a pH of the solution to greater than 2.5; forming a film from the solution, the film comprising a total cationic charge in a range of 0.001 to 10.0 coulombs per square inch, the total cationic charge countered with counteranions; and reducing activity of the pathogen contacting the film by: greater than 9% and less than 99.99995% in less than one minute, greater than 99.999% in less than four days, and greater than 99.99995% in less than seven days.
