Flexible functional materials have been a great interest in various flexible electronic devices. Flexible adhesive is essential for successful assembly of each flexible components and it requires both adhesive and mechanical properties with a thinness. However, these two properties have some trade-off relationship. In this study, various sizes of silica nanoparticle were reinforced to acrylic adhesive in order to investigate the effect of particle size on mechanical and adhesive properties of the composite adhesive film. Furthermore, the nanoparticle was coated with polydopamine to overcome the trade-off relationship and create a synergetic reinforcement of adhesives. Nanocomposite adhesive films were fabricated by appropriate mechanical dispersion and film casting process and several experiments were conducted to prove the synergetic reinforcement effect.
