“…However, the formation and propagation of cracks can permanently damage these materials by high stresses [4,5]. Recently, the exploration of self-healing of polymeric materials (and re-mending them) has become important subject in order to get self-healing material [6][7][8][9]. Polymeric chain entanglements occur with different intermolecular noncovalent interactions cause mending.…”

RETRACTED: Controlled Light Cross-Linking Technique to Prepare Healable Materials

Detection of defects, damages and cracks in structural polymers is very difficult, and even if they are detected, they will be very hard to be repaired. This is because different kinds of stress can reduce the mechanical efficiency of structural and functional thermosetting composite materials and they can damage the polymer matrix, thus reducing the purposed properties. General healing processes use thermal energy "alone" to heal these materials, thus impairing the intended properties of the materials. Therefore, we present a thermal healing ability that can be switched-on and/or -off at desire using illumination by photon energy (visible and ultra violet). By this technique, one can control local heal while keeping the efficiency of the material nearly unchanged. Furan-based cross-linker chemically reacts (forward-and reverse-reaction) with short-chains of maleimide-substituted poly(lauryl methacrylate) to form robust chemical bonds. This permits us to perform local control over thermally induced de-and/or re-cross-linking techniques. One can extend and apply this technique to cover micro-devices, coating-techniques, fine lithography, micro-and nano-fabrication processes, etc. Therefore, the present work developed a suitable technology with structural polymeric material, which has the ability to self-heal cracks (and damages) and recover structural function.

“…The incorporation of healable characteristics in commercial polymers has been a topic of interest in the last decade, as the ability to recover the physical properties of a damaged material potentially permits the development of smart applications that make materials safer, more reliable and durable and reduce maintenance costs [1][2][3][4]. However, the incorporation of such characteristics, by means of the introduction of healing agents, can negatively affect the physical properties of the final product.…”

Abstract. Aromatic disulfide dynamic structures were incorporated as chain extenders in waterborne organic-inorganic polyurethane hybrids in order to provide autonomic healable characteristics. The synthesis was carried out following the acetone process methodology and the influence of the introduction of the healing agents in the polymer dispersion stability was analyzed. After the crosslinking process at room temperature, organic-inorganic hybrid films, which presented autonomic healing characteristics, were obtained. These features were evaluated by means of stress-strain tests and the films showed repetitive healing abilities. Thus, the optimum healing time at room temperature (25°C) as well as the influence of different parameters in the healing efficiency, such the aromatic disulfide concentration or the physical properties of the polymer matrix were analyzed.

“…4,5 In fact, selfhealing is currently one of the most active topics in materials science. [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.…”

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...
