“…This was because of the ionic interaction between polycation PDDA as the second network and polyanion poly(AAm/AMPSA) network, resulting in a large number of sacrificial bonds, which played a role of increasing toughness and energy dissipation, and improved the tensile strength and elongation at break of the HTIG. 25,32 Besides, HTIG3 could recover after 10 tensile cycles under 100% strain (Fig. 3b).…”

“…The healed SLC still retains its original strong stretchable property, as shown in Figure S3 (Supporting Information). The excellent stretchable property and self-healing ability of the SLC are derived from the abundant surface functional groups of glycerol and acrylic resin, which provide additional hydrogen bond (H-bond) binding sites to facilitate cross-linking of the PVA hydrogel chains . In addition, the SLC possesses good elasticity, and the pellets made from it can bounce several times when dropped from a height of 0.5 m, reaching more than half of the height on the first bounce (as shown in Video S2).…”

Triboelectric nanogenerators (TENGs) are demonstrated to possess great superiority in the field of low-frequency and high-entropy energy harvesting. Here, a kind of friction material, super-light clay (SLC), with outstanding stretchability and shape/size changeability is introduced to develop contact-separation triboelectric nanogenerators (SLC-TENGs), which exhibit outstanding flexible, shape-changeable, and adaptable properties but simple preparation processes. A high and stable electrical output can be achieved from the simple-structured SLC-TENG. The peak power density of the SLC-TENG output reaches up to 0.33 W/m2 under an effective contact with an area of 9 cm2 and an external load resistance of 50 MΩ. In addition, a balloon-structured TENG was also prepared with the filling of several SLC balls. The electrical signals can be generated even just by a slight shaking, revealing great application potential in the Internet of Things systems and self-powered sensors by energy harvesting from wind, ocean, human body movements, etc.

“…They can absorb a large amount of water, whereas they will not dissolve in water. As a new type of functional material, hydrogels are broadly used in the fields of biomedicine, − daily chemistry, − and industry. − Recently, a thermoresponsive component has been introduced into the hydrogels to realize the capability of spontaneous response to an external thermal stimulus. For instance, acrylate-based polymers are well known for their thermoresponsive behavior.…”

The simultaneous and efficient removal of oleophilic and hydrophilic stains from polyurethane (PU) is realized by combining the easy-cleaning from the hydrophilic thermoresponsive hydrogel coating containing acrylamide (AAm), gum arabic (GA), and (ethylene glycol) methyl ether methacrylate (OEGMA300) P(GA/AAm/OEGMA300) and the self-cleaning from the embedded nonmetallic photocatalyst g-C3N4. Due to the existence of strong hydrogen bonds between the hydroxyl groups in the hybrid hydrogel coating and the hydroxyl/carboxyl groups in the plasma-treated PU, the hybrid hydrogel coating is very stable on PU. Simultaneously, the acrylamide network in the hybrid hydrogel coating enhances its mechanical strength. Because the transition temperature of OEGMA300 is well above the room temperature, the cross-linked coating remains hydrophilic in ambient conditions. Thus, oleophilic stains, such as oil and grease, can be easily removed from the coating surface. In addition, the embedded photocatalyst g-C3N4 in the hybrid hydrogel coating introduces the extra capability of decomposing organic compounds under sunshine, which favors the removal of hydrophilic stains such as dyes and wines. After sunlight illumination and simply rinsing with water, both hydrophilic and oleophilic stains can be easily removed. Moreover, this joint cleaning performance can work for a long time. Even after four consecutive cycles, both the easy-cleaning to oleophilic stains by the hydrophilic hydrogel surface and self-cleaning to the hydrophilic stains by the embedded g-C3N4 remain unchanged.
