Acrylic pressure sensitive adhesives(PSA) have been widely used in industries such as displays, packaging and Automobile. With the recent development of electronic devices, the demand for adhesives with strong mechanical properties and adhesive strength is increasing, and efforts are being made to improve mechanical properties. In this study, eco-friendly filler, and cellulose nanofiber, was added to the adhesive to increase the mechanical properties. CNF with high aspect ratio has the advantages of high modulus, and strength etc. However, the large amount of OH groups on the cellulose surface decrease the dispersibility of CNF in the polymer matrix. Therefore, we conducted surface modification of CNF to improve the dispersibility. Adhesion, thermal, and mechanical properties of PSAs composites were determined using UTM and TGA. the dispersity of m-CNFs in acrylic resins were investigated by scanning electron microscope and polarization Microscope. |
