“…One advantage of the acrylic primer over a metallic sticking layer such as Cr is that the primer is graft copolymerized onto the PET surface, which enables it to stretch with the underlying PET substrate. [32][33][34][35] As a result, acrylic-primer-coated PET substrates show elongations over 100% without rupture. Cr sticking layers, on the other hand, are intrinsically brittle and form channel cracks at small strains.…”

In this paper, we report that silver films evaporated on poly-ethylene-terephthalate (PET) substrates coated with an acrylic primer can be stretched beyond 70% without fracture. As-deposited films show a larger failure strain than annealed coatings. These observations are rationalized in light of a ductile fracture mechanism where debonding from the substrate coevolves with strain localization. The results of this study indicate that PET substrates coated with an acrylic primer layer may be suitable for stretchable electronics.

“…Polyacrylamide was chosen as the ideal soft substrate due to its common usage in mechanobiology research, established mechanical/chemical stability, and high porosity that would allow diffusion of waste and nutrient products. PET Transwells were chosen due to high transparency for imaging, and the range of options for chemical modification [38][39][40][41][42][43][44][45] . We also considered and trialed several other strategies to functionalise the PET including surface activation with oxygen plasma, silane treatment, and polydopamine coating, however these were discounted as either ineffective due to poor efficacy or undesirable due to the requirement for specialist equipment that may not be available in standard cell culture laboratories.…”

Epithelial cells are well-known to be modulated by extracellular mechanical factors including substrate stiffness. However, the effect of substrate stiffness on an epithelial cell's principal function -creating an effective barrier to protect the underlying tissue -cannot be directly measured using existing experimental techniques. We developed a strategy involving ethylenediamine aminolysis and glutaraldehyde crosslinking to chemically graft polyacrylamide hydrogels with tunable stiffness to PET Transwell membranes. Grafting success was evaluated using spectroscopic methods, scrape tests, and extended incubation in culture. By assessing apical to basolateral transfer of fluorescent tracers, we demonstrated that our model is permeable to biologically relevant molecules and usable for direct measurement of barrier function by calculating paracellular permeability.We found that BEAS-2B epithelial cells form a more effective barrier on stiff substrates, likely attributable to increased cell spreading. We also observed barrier impairment after treatment with transforming growth factor beta, indicating loss of cell-cell junctions, validating our model's ability to detect biologically relevant stimuli. Thus, we have created an experimental model that allows explicit measurement of epithelial barrier function for cells grown on different substrate stiffnesses. This model will be a valuable tool to study mechanical regulation of epithelial and endothelial barrier function in health and disease.

“…The C1s core-level spectra were curve-fitted into two peak components with binding energies at 284.6 and 288.5eV, corresponding to the C-C/C-H and O-C=O functional groups, respectively [18][19][20][21]. In addition, a peak was observed at 283.9eV in the C1s spectra, which was assigned to inhomogeneous charging effect on the polymer surface due to its insulating nature [22].…”

Photo-crosslinkable acrylic copolymer pressure-sensitive adhesives (PSAs) have many applications in the process of electronic industry. As the silicon wafers become thinner, PSAs need to show proper adhesion performance and better debonding characteristics. The acrylic copolymers were prepared with 2-ethylhexyl acrylate, ethyl acrylate, and acrylic acid by radical solution polymerization followed by chemical modification with glycidyl methacrylate to have the photo-crosslinkable groups in the side chains. The adhesion properties of photo-crosslinked acrylic copolymer PSAs were much dependent on both the content of glycidyl methacrylate and the UV dose which played a crucial role in the extent of crosslinking. The clean debonding of PSAs from silicon wafer surface was easily obtained by effective photo-crosslinking of acrylic copolymers modified with glycidyl methacrylate into fully crosslinked networks resulting from controlling the extent of crosslink and the adhesion strength of photo-crosslinked acrylic copolymer
