“…Figure shows that the UV‐curable adhesive containing AA monomer exhibits the greatest adhesion strength to the FTO glass. Because the AA monomer has one acrylate functional group that obtains the highest adhesion strength because it exhibits less shrinkage than adhesives based on monomers with multifunctional acrylate groups …”

Electrolytes were injected through holes in dye-sensitized solar cells (DSSCs), and the holes were subsequently sealed with UV-curable adhesives containing different types of acrylate monomers and different amounts of fluorosurfactants, which were found to affect the performance of the DSSCs during long-term stability tests. The efficiency (η) of the DSSCs' conversion of light to electricity is an important parameter. The corrosion potential (E corr ) toward the liquid electrolyte and the adhesion strength of the UV-curable adhesives to fluorine-doped tin oxide (FTO) glass affected the efficiency of DSSCs during long-term thermal stability tests. The UV-curable adhesive containing 10.0 wt % of acrylic acid (AA) monomer and 3.0-4.0 wt % of fluorosurfactant, when used to seal DSSC devices, led to the best DSSC performance of η = 4.1% during a 45-day long-term thermal stability test.

“…In an extreme case, one of the joint constitutes breaks when shrinkage-induced stress exceeds its tensile strength. Reduction or controlling of the polymerization shrinkage is thus a major challenge in a variety of fields, including electrical potting, fabrication of composite materials, dental filling technology [1] or optics.…”

“…In contrast, our method described in detail in the following section is intentionally designed to perform shrinkage measurements under real conditions in micro-optical systems. Additional charm of this method is the usage of a laser distance sensor [1,11], which provides high spatial and temporal measurement resolution and allows for measurements without physical contact with the probe.…”

Shrinkage Measurements of UV-Curable Adhesives

Curing processes of any adhesive are always accompanied with its volumetric change, known as polymerization shrinkage. Although the relative volume change is usually less than a few percent, shrinkage is particularly problematic for applications where sub‐μm positioning is required, such as bonding of micro‐optics or optical fibers. We present a simple method to precisely measure the linear shrinkage of UV‐curable adhesives based on optical distance measurement. The method allows to observe in situ the dynamics of the shrinkage process.

“…The reduction of distances between molecules creates internal stress throughout the crosslinked material. This reduces the adhesion of the pressure-sensitive adhesive to the joined surfaces [ 1 , 6 , 13 , 14 , 15 , 16 ].…”

The properties of solvent-based pressure-sensitive adhesive (PSA) acrylics, especially shrinkage, are mostly determined by the type and amount of the crosslinking agent added to the prepolymer or by the crosslinking method. The shrinkage profiles of the selected solvent-based acrylic PSA coated on PVC film were investigated using metal chelates (between 0 and 0.55 wt.%), N-methylol acrylamide (up to 8 wt.%), polycarbodiimide and amino resins (up to 6 wt.%), diisocyanate (up to 1 wt.%), multi-functional propylene imines (up to 0.9 wt.%), conventional photoinitiators (up to 3 wt.%) and copolymerizable photoinitiators (up to 2 wt.%). These chemicals were both crosslinking agents that react after the solvent has been evaporated or at higher temperatures, and to the crosslinking agents that react under UV radiation. Some of them were copolymerizable, and others were added to the prepolymer before crosslinking. The best results of shrinkage (0.2%) were obtained by using the UV-crosslinking method and copolymerizable photoinitiators ZLI 3331 and ABP, as well as metal chelates AlACA and TiACA and multifunctional propylene imine Neocryl CX-100 (0.2%). Acceptable results were also achieved for amide BPIA (0.3%), benzophenone derivative PCB (0.4%), N-methylol acrylamide (0.35%) and benzoguanamine resin Cymel 1123 (0.45%).
