Articles and systems involving reaction products on surfaces and associated methods

Abstract

Methods related to forming reaction products on surfaces are generally provided. Some methods comprise applying first and second polyelectrolytes in first and second polyelectrolyte carrier fluids to a surface. The first and second polyelectrolytes may be different, and the first and second carrier fluids may be the same or different. Some methods comprise forming a mixture of the first and second polyelectrolytes in a mixture carrier fluid that comprises the first and/or second carrier fluids. The first and second polyelectrolyte may be removed from the mixture carrier fluid to form a reaction product on the surface. In some embodiments, the mixture carrier fluid comprises a salt with a molecular weight of less than or equal to 1 kg/mol at a concentration within the mixture carrier fluid of from 0.01 M to 0.5 M. In some embodiments, the mixture carrier fluid has a turbidity of greater than or equal to 10 NTU and a viscosity of less than or equal to 1 Pa*s.
