Abstract
Methods of capturing respiratory droplets are provided which use coatings comprising a polyelectrolyte polymer and a viscosity modifier. In embodiments, a method of capturing respiratory droplets comprises absorbing respiratory droplets on a surface of a coating, the coating comprising a polyelectrolyte polymer and a viscosity modifier, wherein absorbed droplets leave depressions in the surface of the coating. Coated substrates and coating compositions used to form the coated substrates are also encompassed.
