Bioinspired pressure-sensitive adhesive: evaluation of the effect of dopamine methacrylamide comonomer as a general property modifier using molecular dynamics simulation

Abstract

The use of catechol-containing comonomers as a general property enhancer to achieve unique properties has received particular attention for designing bioinspired polymeric materials.

Ambient air-operated thermo-switchable adhesion of N-isopropylacrylamide-incorporated pressure sensitive adhesives

“…Interestingly, the peel adhesion values on non-polar substrates such as polypropylene and polyethylene were measured as 9.65 ± 0.87 N/25 mm and 4.88 ± 1.52 N/25 mm, respectively, due to the van der Waals interaction. 45,46 In order to properly investigate the effect of temperature on peel strength, temperature-induced annealing should be evaluated in advance. The effect of annealing on peel adhesion was investigated by annealing the PSAs at different times.…”

Fully Atomistic Molecular Dynamics Simulation of the Structure and Morphology of Small‐Molecular Additives in Rubber Matrices

“…In detail, when the fluctuation range of temperature and energy was from 5% to 10%, the system was considered to have reached equilibrium. [30][31][32][33] For example, Figure 5 illustrated the variation of density and energy of rubber system including the IR and the accelerator TiNTD during the NPT equilibrium. We found that the system reached a stable state after 200 ps, proving that the system has reached a state of equilibrium.…”

A mesh reinforced pressure-sensitive adhesive for a linerless label design

“…2 Waterborne latex-based PSAs are often made from n-butyl acrylate or 2-ethylhexyl acrylate and have small amounts of comonomers which can provide high T g segments (routinely styrene or methyl methacrylate) as well as comonomers which can promote wetting and adhesion, or secondary reversible interactions to improve cohesion (for example (meth)acrylic acid). [3][4][5][6] Commercially, these PSAs are used for labels. A typical label has several layers: a topcoat, a facestock with a printed image or text, the PSA, and a liner which contains a release coating, often made using high molecular weight silicones, to facilitate its removal before application.…”
