Ultrastretchable and adhesive agarose/Ti3C2T -crosslinked-polyacrylamide double-network hydrogel for strain sensor

An agar–polyvinyl alcohol hydrogel loaded with tannic acid with efficient hemostatic and antibacterial capacity for wound dressing

“…2 The compression strength of hydrogels was evaluated by compression test. 35 Also, the hydrogel loaded with PA was also used as a positive control group to study the improvement of TA on the mechanical properties of hydrogels. The details are available in ESI † Materials and methods.…”

MXene/Gelatin/Polyacrylamide Nanocomposite Double Network Hydrogel with Improved Mechanical and Photothermal Properties

“…Notably, with the increase in Ti 3 C 2 T x content from 0 to 0.105 wt%, the compressive strength increased from 2.68 ± 0.130 MPa to 3.44 ± 0.12 MPa, because of the increase in the hydrogen bonds. Nevertheless, when the Ti 3 C 2 T x content increases to 0.140 wt%, the compressive strength slightly decreased to 3.10 ± 0.12 MPa, which is attributed to the destruction of hydrogen bonds caused by the aggregation of Ti 3 C 2 T x [ 26 ]. The tensile stress–strain curves and corresponding tensile strength of hydrogels with different Ti 3 C 2 T x contents are shown in Figure 2 c,d, respectively.…”

“…Recently, we synthesized the agarose/polyacrylamide DN hydrogel, copper-alginate/polyacrylamide DN hydrogel, and agarose/Ti 3 C 2 T x -cosslinked-polyacrylamide DN hydrogel with extremely high mechanical properties by using the γ-ray radiation-induced method [ 24 , 25 , 26 ]. It was found that the γ-ray radiation technology has great advantages in synthesizing high-performance DN hydrogel.…”

A facilely prepared notch-insensitive nanocomposite organohydrogel-based flexible wearable device for long-term outdoor human motion monitoring and recognition

“…With the continuous development of conductive hydrogels, flexible wearable hydrogel devices have attracted considerable attention. 1,2 Based on numerous studies on functional hydrogels such as self-healing, [3][4][5][6] antifreeze, [7][8][9][10] shape memory, [11][12][13] and adhesive, [14][15][16][17][18] researchers have prepared a series of hydrogel sensors. For example, high-performance strain sensors, [19][20][21] pressure sensors, [22][23][24][25] temperature sensors, 26,27 humidity sensors 28 and multimodal sensors, 29 which have potential applications in human health monitoring, 30,31 soft robot, 32,33 biomedical, 34,35 and other fields.…”
