초록

Acrylic-based pressure sensitive adhesive (PSA) has been widely used in diverse industrial applications such as attaching various materials and vehicle painting. Its extensive use is mainly attributed to its excellent transparency, adhesive strength, and chemical resistance characteristics. However, it has been widely accepted that PSA's thermal and mechanical stabilities are not sufficient since it is primarily dependent on the physical interactions of linear molecular structures. In this study, to improve the adhesive's mechanical strength while retaining the adhesion properties of the photocurable acrylic adhesives, polyhedral oligomeric silsesquioxanes (POSS) derivatives were employed as filler materials and their impact on mechanical and adhesive properties was evaluated. Four types of functional groups, methacryl, isooctyl, glycidyl, and acryloisobutyl substituents, were attached to the 8-armed POSSs analyzed in this study. It was observed that the addition of methacryl POSS to the adhesive material induced a significant increase in mechanical strength. The overall physical properties were measured by first controlling the amount of methacryl POSS to keep the POSS wt% of the adhesive compositions between 0.1 to 1 and then assessing the corresponding changes of the acrylic adhesives in terms of tensile strength, strain, peel strength, and surface characteristics. Curing time adjustment and UV/ozone treatments were additionally applied to determine the optimized composition for an acrylic adhesion film.
