Title: Method For Combinatorially Measuring Adhesion Strength.
Abstract: This invention is available for nonexclusive licensing
only. A new method for measuring the adhesive strength of polymer
materials arranged in a combinatorial library is described. In this
invention, a combinatorial library consisting of two parts: A periodic
distribution of curved surfaces, such as a lens array, and a
complementary substrate. These two library components are brought into
contact under controlled displacement conditions. Upon contact, a
combinatorial array of polymer interfaces is created. After reaching
maximum contact, the two library components are separated at a
controlled displacement rate. During both the contact and separation
processes, the contact area created by each contact point and the
corresponding displacement is recorded. This information of contact
area and displacement is used to quantitatively determine the adhesion
energy of the polymer interface. Additionally, a qualitative mapping of
the combinatorial array is simply given by imaging the contact areas
over the entire array. With this information, the conditions for
optimal adhesion at the polymer interface can be determined as a
function of the parameters varied in the combinatorial library. In
addition to empirically determining optimal adhesion conditions for a
specific

application, this technique will have significant impact in guiding the
molecular engineering of optimized adhesive materials for industries
such as, but not limited to, electronic packaging, biomaterials, and
coatings.
