“…[6][7][8] For polymers [9][10][11] and polymer coatings [12][13][14][15] several approaches have been reported to restore the integrity of the material, either by refilling the damaged areas, e.g., a) Electronic addresses: a.c.c.esteves@tue.nl and g.dewith@tue.nl via encapsulated reactive components (autonomous healing) or by reestablishing chemical bonds through reversible reactions triggered by external stimuli such as temperature, light or a pH switch (triggered healing). These approaches can use intrinsic healing concepts, [16][17][18][19] in which the healing agent is inherent to the material (i.e., is a part of the network or formulation) or extrinsic healing, where external components are added, such as filled capsules [20][21][22][23] or microvascular networks. 24,25 The intrinsic healing concept may allow multiple healing events but requires a certain mobility of the system (or at least part of it).…”

Nowadays, many self-healing strategies are available for recovering mechanical damage of bulk polymeric materials. The recovery of surface-dependent functionalities on polymer films is, however, equally important and has been less investigated. In this work we study the ability of low surface energy cross-linked poly(ester urethane) networks containing perfluorinated dangling chains to self-replenish their surface, after being submitted to repeated surface damage. For this purpose we used a combined experimental-simulation approach. Experimentally, the cross-linked films were intentionally damaged by cryo-microtoming to remove top layers and create new surfaces which were characterized by water Contact Angle measurements and X-Ray Photoelectron Spectroscopy. The same systems were simultaneously represented by a Dissipative Particles Dynamics simulation method, where the damage was modeled by removing the top film layers in the simulation box and replacing it by new "air" beads. The influence of different experimental parameters, such as the concentration of the low surface energy component and the molecular m...

“…Respectively, the compliance was totally recovered at the reloading stage only at the presence of shape memory alloys (compared to unreinforced healed material that plastically deformed without building significant compliance regain). On other studies, the use of short-groove TDCB samples ensured compliance regain (Figure 11d) and considerable restoration of material original stiffness [60,36].…”
