Method to substantially enhance shelf life of hygroscopic components and to improve nano-manufacturing process tool availablity
First Claim
1. A component having a porous surface, the surface having reduced susceptibility to moisture exposure, comprising:
- a component having a non-adhered moisture barrier disposed on the porous surface of the component, wherein the non-adhered moisture barrier comprises a blocking gas disposed in pores on surface of the component, wherein the component is selected from the group consisting of a medical component, an orthopedic component, a prosthetic component, a rechargeable battery cell having high surface area, and a fuel cell having high surface area; and
a sealed air-tight package having the component disposed therein, wherein the blocking gas is selected relative to a size of the pores on the surface to form the non-adhered moisture barrier such that the blocking gas remains in the pores on the surface after the sealed air-tight package is opened.

Abstract
A process has been developed that significantly reduces moisture absorption of components, resulting in a component which is less susceptible to moisture and adsorption/absorption effects to the components functionality. In one embodiment, a component having reduced susceptibility to moisture exposure includes a component disposed in an air-tight package, the component having a blocking gas disposed in pores on a surface of the component. In another embodiment, a method for preparing a component having reduced susceptibility to moisture exposure includes driving water from a component in a controlled environment, exposing the component in the controlled environment to a blocking gas, removing the component in the controlled environment, and optionally sealing the component in an air-tight package.
