Abstract
A flexible substrate includes a polymer substrate. At least a portion of a first barrier region is formed on a neutral plane of the polymer substrate. A top region is formed above the first barrier region. A bottom region is formed below the first barrier region. The first barrier region includes a first inorganic material disposed in at least a portion of a free volume of the polymer substrate. A density of the first inorganic material in the first barrier region is greater than a density of the first inorganic material in the top or bottom regions.
Claims17
A method of manufacturing a flexible substrate, the method comprising:
- injecting a first reactant above a polymer substrate into a top surface of the polymer substrate and infiltrating the first reactant into the polymer substrate;
- injecting a second reactant below the polymer substrate into a bottom surface of the polymer substrate and infiltrating the second reactant into the polymer substrate;
- and
- forming a barrier region by filling at least a portion of a free volume of the polymer substrate with an inorganic material formed via a reaction of the first and second reactants inside the polymer substrate.
A method of manufacturing a flexible substrate, the method comprising:
- Infiltrating a first reactant into substantially an entire polymer substrate;
- removing the first reactant infiltrated into a top region in the polymer substrate;
- infiltrating a second reactant into at least a portion of the polymer substrate;
- and
- forming a barrier region by filling at least a portion of a free volume of the polymer substrate with an inorganic material formed via a reaction of the first and second reactants inside the polymer substrate.
