The design of advanced functional materials from polymers involving 2-octyl acrylate and isobornyl monomers is crucial for applications such as biofouling resistance, coatings, UV-curable films, use in marine environments. In this study, we investigated the adsorption electronic properties presence Cl−, Na+, Mg2+ ions using Density Functional Theory calculations. Adsorption energies, quantum descriptors, electrostatic potential maps were analyzed to elucidate ion-specific interactions with these monomers. Our findings indicate that exhibit strongest due their high charge density, followed by Na+ Cl− ions, which show moderate weak adsorption, respectively. states analyses revealed significantly lowers HOMO LUMO levels, narrowing gap stabilizing system, while result a smaller weaker interactions. Electrostatic further confirmed trends, correlating ion sites molecular distributions. This study highlights critical role its associated paves way future advancements optimizing acrylate-based coatings

Most acrylate adhesives do not bond well to low-surface-energy substrates (e.g., polyethylene and polypropylene) due the weak interaction force between polar adhesive molecules substrate. To enhance adhesion performance on investigate effects of substrate surface energy, roughness, pressure-sensitive (PSA) viscosity, modulus performance, this study modifies by incorporating a hydrogenated-terminated hydroxylated polybutadiene (HHTPB) structure with double at one end. The results demonstrate an enhancement in modified PSAs High-Density Polyethylene (HDPE). 24 h peel strength loop tack increase 4.88 N/25 mm 8.14 20 °C, respectively, failure modes remaining failure. However, as temperature increases, decreases. high-temperature resistance improves. Based experimental data, mathematical model is proposed that incorporates both wetting area loss factor predict strength. influence these two factors PSA dependent application adhesive.
