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 Start Printed Page 70214application, 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.Start Signature
