“…For the separation force to equal the adhesion force, it is required that the analogy to Tate's law will be insensitive to the direction of the separation process, since the liquid−liquid separation is vertical to the solid−liquid separation. Such a requirement is justified if we consider adhesion studies done on adhesive tapes 34 where the peeling force is insensitive to the peeling direction for tapes with low elastic modulus. Yet, more studies are needed to address it theoretically.…”

We establish a tool for direct measurements of the work needed to separate a liquid from a solid. This method mimics a pendant drop that is subjected to a gravitational force that is slowly increasing until the solid-liquid contact area starts to shrink spontaneously. The work of separation is then calculated in analogy to Tate's law. The values obtained for the work of separation are independent of drop size and are in agreement with Dupré's theory, showing that they are equal to the work of adhesion.

“…It is experimentally demonstrated that higher peel rates cause higher peel force 25,39–41 . The primary reason is changing the effective length of cohesive zone in the adhesive layer which is changing dramatically by the peel rate.…”

The adhesion strength of thin films is critical to the durability of micro and nanofabricated devices. However, current testing methods are imprecise and do not produce quantitative results necessary for design specifications. The most common testing methods involve the manual application and removal of unspecified tape. This overcome many of the challenges of connecting to thin films to test their adhesion properties but different tapes, variation in manual application, and poorly controlled removal of tape can result in wide variation in resultant forces. Furthermore, the most common tests result in a qualitative ranking of film survival, not a measurement with scientific units. This paper presents a study into application and peeling parameters that can cause variation in the peeling force generated by tapes. The results of this study were then used to design a test methodology that would control the key parameters and produced repeatable quantitative measurements. Testing using the resulting method showed significant improvement over more standard methods, producing measured results with reduced variation. The new method was tested on peeling a layer of paint from a PTFE backing and was found to be sensitive enough to register variation in force due to differing peeling mechanisms within a single test.

“…At higher concentrations than 0.4 wt %, both hydrogels with 9 and 18 kPa of elastic modulus were broken before the detachment at the glued area because PDMA hydrogels are weaker than the nanoparticle-mediated bridge. Therefore, a 90° peel test − was performed to measure the adhesion energy produced at a higher concentration of deposited solutions. Using the same 9 kPa PDMA hydrogels, the 90° peeling test was performed at a constant speed of 150 mm/min, as described in Figure a.…”

Colloidal Supraballs of Mesoporous Silica Nanoparticles as Bioresorbable Adhesives for Hydrogels

et al. 2022

The adsorption of polymers at the surface of mesoporous silica nanoparticles (MSNs) has been shown to provide a versatile way to create adhesion between hydrogels or biological tissues. Nevertheless, above a critical number of deposited nanoparticles, thick multilayers accumulate at the interface and the adhesion strength decreases as cracks easily propagate between weakly cohesive polymer-free nanoparticles. In order to suppress this limitation, we prepared spherical aggregates by spray drying during which MSNs are strongly adhered to by thermal annealing. The coatings produced with these microscopic supraballs (SB-MSNs) exhibit the same high specific surface area as MSN layers but with a much stronger cohesion between nanoparticles. Lap-shear tests with polydimethylacrylamide hydrogels clearly showed that the adhesion energy with supraballs can be significantly enhanced compared with nanoparticles (∼200% at 0.4 wt %). Peeling tests showed that the maximum adhesion energy reached with SB-MSNs (8 ± 0.5 J/m2) is significantly higher than the one achieved with nonaggregated nonporous (3 ± 0.1 J/m2) or mesoporous (6 ± 0.4 J/m2) SNs. It can be even further increased (10 ± 0.4 J/m2) by using macroporous supraballs. Moreover, confocal observations reveal that the largest adhesion enhancement obtained at high deposition concentrations is related to the formation of corrugated interfaces stabilized by supraballs. Finally, SB-MSNs degrade in biological media at the same rate as the elementary mesoporous nanoparticles, therefore offering an interesting combination of adhesion and bioresorbability for use as bioadhesives.
