PSA has been widely used in industries such as displays, packaging, and automobiles. Recently, with the development of electronic devices, demand for adhesives with strong mechanical properties and strong adhesive force is increasing, and efforts to improve mechanical properties are continuing. In this study, the mechanical properties of adhesives (PSA) were enhanced by adding eco-friendly fillers. CNF has advantage of high modulus, reinforcement due to high aspect ratio etc. However, the dispersibility of the polymer blend is not good because of many hydroxyl groups on the surface of the cellulose. To improve the dispersibility modifying the cellulose was used. We determined adhesive, thermal, and mechanical properties of the PSAs composites using UTM and TGA. Furthermore, the electron microscope and polarization microscope were measured to investigate the m-CNF dispersion of acrylic resin.
