We report a memory device based on organic− inorganic hybrid cellulose−Ti 3 C 2 T X MXene composite hydrogel (CMCH) as a switching layer sandwiched between Ag top and FTO bottom electrodes. The device (Ag/CMCH/FTO) was fabricated by a simple, solution-processed route and exhibits reliable and reproducible bipolar resistive switching. Multilevel switching behavior was observed at low operating voltages (±0.5 to ±1 V). Furthermore, the capacitive-coupled memristive characteristics of the device were corroborated with electrochemical impedance spectroscopy and this affirmed the filamentary conduction switching mechanism (LRS-HRS). The synaptic functions of the CMCH-based memory device were evaluated, wherein potentiation/depression properties over 8 × 10 3 electric pulses were observed. The device also exhibited spike time-dependent plasticity-based symmetric Hebbian learning rule of a biological synapse. This hybrid hydrogel is expected to be a potential switching material for low-cost, sustainable, and biocompatible memory storage devices and artificial synaptic applications.

With the rapid development of the electronic industry and wireless communication technology, electromagnetic interference (EMI) or pollution has been increasingly serious. This not only severely endangers the normal operation of electronic equipment but also threatens human health. Therefore, it is urgent to develop high-performance EMI shielding materials. The advent of hydrogel-based materials has given EMI shields a novel option. Hydrogels combined with conductive functional materials have good mechanical flexibility, fatigue durability, and even high stretchability, which are beneficial for a wide range of applications, especially in EMI shielding and some flexible functional devices. Herein, the current progress of hydrogel-based EMI shields was reviewed, in the meanwhile, some novel studies about pore structure design that we believe will help advance the development of hydrogel-based EMI shielding materials were also included. In the outlook, we suggested some promising development directions for the hydrogel-based EMI shields, by which we hope to provide a reference for designing hydrogels with excellent EMI shielding performance and multifunctionalities.

In this work, a robust and mechanically composite hydrogel with an efficient electromagnetic interference shielding performance was successfully fabricated via the incorporation of Lcitrulline-modified Ti 3 C 2 T x MXene nanosheets into the polyacrylamide/sodium alginate hydrogels by using ferrous chloride as the adhesive. A L-citrulline-modified Ti 3 C 2 T x MXene nanosheet was the main shielding medium; ferrous chloride could not only enhance the mechanical property of the resultant hydrogels but also slightly improve the EMI shielding efficiency. The optimal tensile strength (3.42 MPa) and the EMI shielding effectiveness (26.8 dB) were achieved for the composite hydrogels with 6.5 wt % L-citrulline-modified Ti 3 C 2 T x MXene nanosheets and 0.6 mol/L ferrous chloride, and the high ductility (780% elongation at break) of the composite hydrogel was reached with 0.5 wt % L-citrullinemodified Ti 3 C 2 T x MXene and 0.8 mol/L ferrous chlorides. With outstanding mechanical and EMI shielding performances, the prepared composite hydrogels could apply in the electronic skin field.
