“…These have a high refractive index, which can contribute to clearer images on a display. Acrylic PSAs can be obtained through various polymerization processes such as the emulsion [7][8][9], solvent-type [10], water-borne [11], and radiation polymerization techniques [5]. However, much attention has recently been devoted to the use of more environmentally friendly processes, such as the ultraviolet (UV) technique.…”

In order to overcome the issues of rework and height difference in the manufacturing of smart devices, UV/UV stepwise curing was conducted on acrylate-based optically clear adhesives. Photo differential scanning calorimetry was used to confirm the results of curing of samples that were processed both with and without acrylic acid, over a range of UV light exposure times for a primary curing process. The samples processed at 0.6 J/cm 2 of UV energy with and without acrylic acid showed the highest amount of residual monomers after primary curing. The amount of residual monomers observed in primary-cured samples decreased as the amount of UV light energy increased, from 0.9 to 1.5 J/cm 2. After secondary curing, only the samples cured at 0.6 J/cm 2 showed small amounts of residual monomers, while the samples exposed to other UV energies showed very few residual monomers, implying that these samples were completely cured during the secondary curing step. Adhesion properties were evaluated using peel and tack tests, while the viscoelastic properties of the samples were confirmed by dynamic mechanical analysis. Our results indicate that uniform physical properties were achieved after secondary curing. The effects of stepwise curing are demonstrated by the difference in gel fractions determined after primary and secondary curing.

This study designs less corrosive optically clear adhesives (OCAs) with good rework properties, where copolymer and glycidyl methacrylate (GMA) are cured by ultraviolet to form OCAs. The copolymer are synthesized by using N,N-diethylacrylamide (DMA), acrylic acid (AA), and 2-ethylhexyl acrylate. The DMA and AA could form acid-base interaction and therefore lower the corrosion on metallic substrate caused by AA. Copolymer is applied in OCAs, as different adhesive properties are presented. In terms of the adhesive property of OCAs, the peel strength, shear strength, and transmittance property are decreased when the GMA concentration is increased. The tack and haze are enhanced accordingly. After 7 days' standing at 60 8C and 90% RH, OCAs have no obvious corrosion on the conductive glass circuits, and there is no residue after peeling off.
