ABSTRACT:
Various methods of forming a chemical barrier against the transmission of disease-causing microbes and other harmful agents through a membrane fashioned of latex or other material. In one method, the latex material is provided with microbe sterilization properties by deforming the latex material from a relaxed condition such that the pores therein are deformed, then washing the deformed latex material with a biocide, which is entrapped in the pores, and then relaxing the latex material. Alternatively, instead of washing the deformed latex material with the biocide, the biocide may be mixed directly with the liquid latex preferably along with a buffer agent and then the liquid latex can be cured. In yet another method, the latex material is treated with a silicone, protein or high molecular polyion to form a water resistant surface. A method of inhibiting the deterioration, extending the effective life, increasing the strength, and increasing the elasticity of the latex material is to mix an oxidation reducing agent that chelates iron and other heavy metals with the liquid latex and then to cure the latex. The latex materials produced by the foregoing methods are also disclosed.
