“…Hydrogels are a class of materials consisting of physically or chemically cross-linked polymer chains that contain a large quantity of water. They have been applied to functional materials and devices such as soft contact lenses, cell sheets, artificial articular cartilages, etc. − The performance of these materials and devices is closely related to their frictional properties, especially in water. Thus, to design better materials and devices, molecular-level studies with the aim of providing a better understanding of the frictional properties for hydrogels should be widely conducted.…”

Frictional properties play a key role in the performance of hydrogels in applications such as soft contact lenses, cell sheets, artificial articular cartilage, etc. Here we characterize the swollen state and frictional properties of thin hydrogel films composed of poly(2-methoxyethyl vinyl ether) on a nanometer scale using neutron reflectivity (NR) in conjunction with lateral force microscopy, leading to the discussion about the extent to which surface chains impact the frictional properties of gels. NR measurement revealed that the density profile for the hydrogel films in the interfacial region with water along the direction normal to the interface was well described by a parabolic function, which was generally used for swollen polymer brushes in a liquid. Lateral, or frictional, force (F L) first increased with increasing normal force (F N) and then reached a region where the dependence of F L on F N was extremely subtle. That is, there exist two regimes, I and II, for the relationship between F N and F L. The thickness of the interfacial layer composed of dangling chains, which should behave like brush chains, as determined by NR measurement, was in good accordance with the depth at which the regime transited from region I to II. The frictional properties of the thin hydrogel films could be better understood by considering the two contributions from the interfacial layer and the internal bulk region.

“…Moreover, the reversible physical cross-links in the hydrogel bestowed intrinsic self-healing. As the properties of this hydrogel mimic the self-healing ability of skin and provide easy actuation as of muscles, it is hoped to be used in fabricating artificial skin or muscle . This indicates that the conductivity in the polymers help reform or actuate muscles more dominantly than the nonconducting polymers.…”

Shape memory-assisted self-healing polymers have drawn attention over the past few years owing to their interdisciplinary and wide range of applications. Self-healing and shape memory are two approaches used to improve the applicability of polymers in the biomedical field. Combining both these approaches in a polymer composite opens new possibilities for its use in biomedical applications, such as the "close then heal" concept, which uses the shape memory capabilities of polymers to bring injured sections together to promote autonomous healing. This review focuses on using shape memory-assisted self-healing approaches along with their respective affecting factors for biomedical applications such as tissue engineering, drug delivery, biomaterial-inks, and 4D printed scaffolds, soft actuators, wearable electronics, etc. In addition, quantification of self-healing and shape memory efficiency is also discussed. The challenges and prospects of these polymers for biomedical applications have been summarized.

This work's aim was to perform a review of the scientific literature from the standpoint of both the architect and builder. In the first place, on which self-healing materials are currently available for construction industry; secondly, to acknowledge the main applications and the self-healing methods of each material. The review was largely carried out using the scientific database tool sciencedirect ® and other similar tools on the main applications of self-healing materials in construction industry. The results reveal that the main applications refer to the production of self-healing concretes and mortars by means of self-healing techniques, for example: insertion of microcapsules with various self-healing agents, followed by self-healing bacteria. It is concluded that with the use of these materials not only does the service life of structures of buildings improves, but also that of the entire building, increasing durability and noticeably decreasing maintenance and reparation costs.
