“…Similarly, two adjacent sharp bands at 2917 and 2846 cm –1 represent the stretching vibrations of CH 3 and CH 2 within the hydrogel network, respectively. , Additionally, the sharp band at 1655 cm –1 corresponds to the stretching vibrations of CO present in the polymer chain in the AM and AETAC. The peak at 1467 cm –1 signifies the bending of C–H, and this region also contains carboxylate groups. , Upon the addition of BM-MOFs to the hydrogel CM2, a red shift is observed in the NH 2 group, with the broad peak shifting from 3368 to 3342 cm –1 .

Metal−organic frameworks (MOFs) are widely applied in various fields, including energy storage, drug delivery, wastewater treatment, and much more. However, their use in hydrogels is limited due to their low dispersion which causes agglomeration in the hydrogel network and many properties of hydrogels are sacrifices. Similarly, conductive hydrogels have emerged as a promising material for skin-like sensors due to their excellent biocompatibility and mechanical flexibility. However, like MOFs, hydrogels also face challenges such as limited stretchability, low toughness, and susceptibility to fatigue, resulting in a low sensing range and large response time-reduced durability of the sensors. In this study, a highly stretchable, tough, and antifatigue conductive composite poly(dodecyl methacrylateacrylamide-2-(acryloyloxy)ethyl trimethylammonium chloride) bimetallic metal−organic framework [p(DA-AM-AETAC)BM-MOF] hydrogel was developed by integrating BM-MOFs into it. To achieve uniform dispersion of BM-MOFs within the hydrogel network, a positively charged surfactant, ethyl hexadecyl dimethylammonium bromide, was used. It facilitates the formation of hydrophobic interactions between the hydrogel matrix and the surface of the BM-MOFs. Furthermore, it can also interact with surfactant and polymer chains through physical interactions, significantly enhancing the mechanical properties of the hydrogel. The resulting BM-MOF-based hydrogels exhibited impressive stretchability (1588%) and toughness (537 kJ m −3 ), along with exceptional antifatigue properties. Moreover, it demonstrated a high conductivity of 1.3 S/m and high tensile strain sensitivity ranging from 0.5 to 700% with a gauge factor of 14.8 at 700% strain and response−recovery of 195−145 ms. The p(DA-AM-AETAC)BM-MOF hydrogel sensors displayed sensitive, reliable, and repetitive detection of a wide range of human activities, including wrist elbow rotation, finger bending, swallowing motion, speaking, as well as handwriting and drawing. Furthermore, the hydrogels also monitor the pressure and can mimic human skin. This highlights the potential of hydrogels as wearable strain, pressure, and artificial skin sensors for flexible devices.

“…Final weights were measured to determine their swelling amount. Swelling capacities (ESR, gwater/ghydrogel) of p(AETAC)/AC composite hydrogels were calculated (Güngör & Ozay, 2022b). In addition, the effects of various waters (sea water (SW), river water (RW), synthetic textile waste (STWw), tap water (TW), and drinkable water (DbW)) on the swelling behavior of p(AETAC)/AC75 composite hydrogel were investigated.…”

Water-insoluble p(AETAC)/AC composite hydrogels containing quaternary ammonium were prepared by free-radical polymerisation method with [2-(Acryloyloxy)ethyl]trimethylammonium chloride (AETAC) and activated carbon (AC). The composite hydrogel was characterized by Fourier Transform Infrared Spectroscopy (FT-IR), Thermogravimetric analysis (TGA), X-Ray Diffraction (XRD), and Scanning Electron Microscopy (SEM) methods. In addition, the swelling behavior of p(AETAC)/AC composite hydrogels containing 50 mg, 75 mg, 100 mg, and 150 mg AC in deionized water was investigated. The swelling capacity of the p(AETAC)/AC75 composite hydrogel containing 75 mg AC in various waters was determined. Initial dye concentration, contact time, pH of dye solution, amount of adsorbent, and temperature parameters affecting MO adsorption of p(AETAC)/AC75 composite hydrogel were investigated. The obtained adsorption data agree with the Langmuir isotherm model and the PFO kinetic model. It was determined that the maximum adsorption ability of p(AETAC)/AC75 composite hydrogel according to Langmuir isotherm was 909.09 mg/g. ΔH° and ΔS° values for the adsorption of MO dye-stuff of p(AETAC)/AC75 composite hydrogel were calculated as 22.25 ± 1.43 and 85.40 ± 4.60, respectively. In addition, the value of ΔG° less than zero at four different temperatures indicates that the dye adsorption is spontaneous. According to all the data obtained, p(AETAC)/AC75 composite hydrogel can be considered a promising candidate for the removal of anionic dyestuffs from water.
