Abstract:
A method of measuring the adhesive strength of a polymer interface which comprises the steps of:a) providing a lens array having a plurality of individual lens elements on a surface thereof; b) providing a substrate; c) applying a polymer to at least one of the individual lens elements of the lens array or the substrate; d) contacting the individual lens elements of the lens array and the substrate in a controlled manner; e) separating the individual lens elements of the lens array and the substrate in a controlled manner; f) monitoring changes in contact area of the individual lens elements during at least one of steps d) or e); and g) calculating the adhesive strength of the polymer at the contact area, wherein the step c) of applying the polymer comprises varying at least one of a thickness and a composition of the polymer across the one of the individual lens elements of the lens array or the substrate.
