Materials with self-healing property are considered as the smart materials for various advanced technological applications. Previously only living substances such as tissues were thought to have self-healing properties that are required for their survival and adaptation to environmental changes. Recently, novel synthetic materials such as hydrogels have been prepared and developed which demonstrated self-healing performances. Exceptional self-healing has been observed in hydrogels introducing different kinds of nanoparticles. These hydrogels have exceptional functionality and mechanical properties. The techniques of the introduction, exploration, and measurement of the properties related to self-healing are challenging due to the wide variety of substances. In this chapter, efforts have been made to discuss the mechanism, types, and drawbacks of nanomaterial-modified self-healing hydrogels.

A versatile magnetite based stringent polymer for effective metal capture was prepared by reacting iron oxide based initiator with glycidyl methacrylate monomer via single-electron transfer living radical polymerization (SET-LRP) technique. The versatile grafted polymer was successfully synthesized by metal catalyzed living radical polymerization using the catalyst system Cu/N,N,N',N'',N'''-pentamethyldiethylenetriamine as the ligand. The structural confirmation of the initiator and the grafted polymer was analyzed by using instrumentation methods such as proton nuclear magnetic resonance spectroscopy, UV-visible, TGA, SEM and gel permeation chromatography for molecular weight measurements. As the polymerization time increased, both the conversion and the molecular weight were observed to increase linearly with time. Narrow dispersed lower polydispersity index (PDI) and dispensable magnetite-g-PGMA was utilized for the extract of toxic lead from the wastewater. Sustained binding was observed due to the presence of epoxide ring in the repeating units of the polymer and recovered by magnetic effect. The material shows good stability as evident by TGA curves and better affinity to toxic lead as observed by UV-visible and SEM techniques.

Flexible and wearable sensors based on nanocomposite hydrogels have been used to monitor human physiological signals. However, it is still a challenge to develop flexible sensors using self-healing hydrogels with the properties of biocompatibility and flexibility. In this manuscript, Janus nanosheets were implanted into guar gum (GG)/poly(vinyl alcohol) (PVA) 3-dimensional network structure. The obtained flexible sensor with nanocomposite hydrogels had outstanding flexibility, high sensitivity, and excellent durability. In typical oil-in-water (O/W) Pickering emulsion, GO-poly(4-vinylphenylboronic acid)/polydopamine Janus nanosheets (JNs) were surface-initiated with 4-vinylphenylboronic acid (4VPBA) on the side of GO by RAFT polymerization and self-polymeriztion of dopamine (DA) on the other side by mussel-inspired chemistry, respectively. The JNs hydrogels had the preferable mechanical strength (1.0 MPa) and self-healing efficiency (93.1%) in the presence of reversible interaction. The resistive-type hydrogels sensor with these JNs hydrogels exhibited high sensitivity (gauge factor (GF) = 12.5) and antifatigue sensing performance (100% strain, 600 cycles). The sensor could monitor different human movements, which includes both large-scale (wrist bending, elbow bending, and running) and small-scale (cough vibrations, pulse rates, and finger bending) motion precisely. These nanocomposite hydrogels will provide strategies for wearable flexible sensors with superior stability and repeatability.
