Abstract
A process for preparing a composite including mixing a hydrophilic material containing an amine with a hydrophobic material containing an acid releasing agent, the hydrophilic and hydrophobic materials being substantially free of water, to form a mixture. The mixture is exposed to chlorine dioxide which reacts with the amine to form iminium chlorite within the hydrophilic material. The hydrophilic material is capable of releasing chlorine dioxide upon hydrolysis of the acid releasing agent.

A process for preparing a composite comprising:
- mixing a hydrophilic material containing an amine with a hydrophobic material containing an acid releasing agent, the hydrophilic and hydrophobic materials being substantially free of water, to form a mixture;
- and
- exposing the mixture to chlorine dioxide that reacts with the amine to form iminium chlorite within the hydrophilic material, the hydrophilic material being capable of releasing chlorine dioxide upon hydrolysis of the acid releasing agent.
A process for preparing a composite comprising:
- providing a hydrophilic material containing an amine and a hydrophobic material containing an acid releasing agent, the hydrophilic and hydrophobic materials being adjacent and substantially free of water;
- and
- exposing the adjacent materials to chlorine dioxide that reacts with the amine to form iminium chlorite within the hydrophilic material, the hydrophilic material being capable of releasing chlorine dioxide upon hydrolysis of the acid releasing agent.
