| Outline of Final Research Achievements |
In this study, we aim to establish an isostatic press (IP) method, by which low-molecular-weight and polymeric organic thin films are wholly densified and strengthened, and optimize conditions of coating and pressing pressure. All the low molecular films have been successfully densified by the IP method. Densifying rates of the films ranged from 40% of metal-free phthalocyanine films to 8.4% of pentacene films depending on their grain shapes and aggregation conditions. Two polymeric films also have densified over the rate of 15%. The indentation hardness of as-coat PMMA films was improved by a rate of 40% with the IP method. PEDOT/PSS films have been densified by adding a organic solvent into the pristine solution.
