“…The maximum detachment force is noted and considered a measure of adhesion strength. Such factors as peel angle [9], peel rate [11,12] and dwell time [13] have great influence on the peel force.…”

A model material simulating the mechanical and surface properties of a real human skin was developed for use as a substrate in adhesion-to-skin evaluation. It is a protein-lipid composition possessing film-forming ability. The composition is based on gelatin plasticized by glycerol, polysaccharides and a mixture of lipids that mimick the skin's lipid structure and creates a hydrophobic surface. To enhance the material hydrolytic stability, the composition was cross-linked by formaldehyde, producing a water-swellable but insoluble matrix. The surface topography of a real skin was achieved by a silicone replica technique. Thin films with thickness of 100 ± 10 µm were cast. The effect of the components ratio and preparation technique on the film mechanical, surface and hydrolytic properties was studied. Based on the results obtained, a formulation having mechanical and surface properties comparable to that of a human skin was selected. The relevance of the model material was evaluated in lap-shear and 180 • -peel adhesion tests and the results were compared to a finger or a forearm skin of ten healthy volunteers (in vivo tests). For validation purposes, commercial surgical tapes Micropore™ and Transpore™ and Mylar ® polyester film were also used. The effects of substrate, adhesive, conditions of the joint preparation and the test employed on adhesion strength were studied. The results obtained show that the mechanical and surface properties of the model material are close to those of the human skin.

“…In summary, we have shown that in a simple model of peeling adhesion hysteresis arises due to energy lost at transitions between metastable states [25,26], a result that is preserved in the continuum limit. This is similar to a phenomenon in polymer fracture known as the Lake-Thomas effect [42,43], wherein the energy required to rupture an elastomer is much larger than the energy to break all the typical density of chains crossing the fracture plane [44], due to the energy loss when the stretched chains away from the fracture zone relax as the crack propagates [3,[44][45][46][47][48]. This notion of stretching globally while breaking locally can also be observed in our model, where at a given moment the adhesive bonds within a region of size l H are stretched whereas upon peeling or healing, energy is released from a single spring, spanning a region of size ∆l.…”

Adhesive interactions between elastic structures such as graphene sheets, carbon nanotubes, and microtubule axonemes exhibit hysteresis due to irrecoverable energy loss associated with bond breakage, even in static (rate-independent) experiments. Here we provide a simple theory that explains how bond breaking and elastic relaxation can drive static adhesion hysteresis over a debonding/rebonding cycle. We show that energy loss emerges from the coupling of a local event (bond breaking) to a nonlocal event (overall elastic relaxation), in a manner similar to the Lake-Thomas effect in polymers. Experiments with adherent microtubules allow us to quantify the hysteresis as a function of adhesion and elasticity parameters. Our model also helps guide the derivation of a self-consistent continuum boundary condition at the interface of adherent mechanical systems.
