Delamination and Wrinkling of Flexible Conductive Polymer Thin Films

Polymer based conductive and transparent thin films are an important class of functional materials at the heart flexible organic electronic devices. These prone to degradation mechanical instability leading formation blisters, wrinkles, cracks. This is detrimental their use especially in case multilayer Here, it shown that a simple water or solvent drop deposited on such gives rise buckling several folds due tendency these swell contact with solvent. A phase diagram portraying its domain existence, thus means inhibit it, proposed. By depositing drops observing instability, material parameters as elastic modulus energy adhesion substrate can be estimated reliably. Further, harnessed pattern surfaces low cost giving percolated more pathways polymer under scrutiny.
