“…Dimethylamino-2-ethyl methacrylate (DMAEMA), a tertiary amine group containing water soluble monomer, is frequently used to synthesize functionalized polymers and functionalized amphiphilic copolymers. Some novel and valuable properties including hydrophilicity [5,19,20,22,26], temperature [19,26], pH [19][20][21]26], ionic strength [19,22] stimuli-responsive behaviors, drugs adsorption ability [35], anions [36,37] adsorption properties, will be endowed to the pristine matrixes, when using PDMAEMA as modifiers. Furthermore, with some simple chemical modification, the PDMAEMA containing membranes can even exhibit the antibacterial properties after having been quaternized [38] and fouling-resistance after zwitterionicalization [5].…”

“…Methyl methacrylate (MMA) is a lowcost hydrophilic monomer which can be easily polymerized to a desirable sequence structure and can be copolymerized with many functional monomers [28,29]. The compatibility between PMMA and typical membrane materials poly(vinylidene fluoride) (PVDF) and poly(vinyl chloride) (PVC) makes MMA a suitable monomer for synthesizing amphiphilic copolymers with desirable sequence structures for PVDF based blend membranes [33][34][35][36][37]. Dimethylamino-2-ethyl methacrylate (DMAEMA), a tertiary amine group containing water soluble monomer, is frequently used to synthesize functionalized polymers and functionalized amphiphilic copolymers.…”

“…6b, the adsorbed Cr(VI) can be eluted in solution of pH 9.7. The desorption ratios of Cr(VI) ions from the blend membranes (almost 95%) were slightly higher than those from the quaternary ammonium based amphiphilic gels [25]. The washed membranes still performed perfectly in further Cr(VI) adsorption tests.…”

“…Dimethylamino-2-ethyl methacrylate (DMAEMA) is a tertiary amine containing monomer frequently used to synthesize hydrophilic and multifunctional polymers or amphiphilic copolymers. Modified by PDMAEMA-containing copolymers can endow the pristine matrixes with hydrophilicity [17][18][19][20], permeation and separation stimuli-responsive behaviors [20,21], drug adsorption ability [22], anion adsorption ability [23][24][25][26], and even antibacterial properties after being quaternized [27]. Poly(methyl methacrylate) (PMMA) has been proved as the proper hydrophobic components due to its synthesis efficiency and good compatibility with PVDF [28][29][30].…”

“…Hexavalent chromium (Cr(VI)) is a type of carcinogenic and toxic heavy metal elements which are becoming great threats to human health and environment [33,34]. Conventional methods for removing Cr(VI) from water include chemical precipitation, adsorption, and membrane filtration [23][24][25][33][34][35][36][37][38][39]. Cr will accumulate in living organisms.…”

Hydrogels are 3D crosslinked hydrophilic polymer networks with a large quantity of water, [1][2][3] which have been applied to a wide range of fields such as chemical sensors, water treatment, human-machine interface, electronic skin, and biomedical engineering in recent decades. [4][5][6][7][8][9] However, the weak mechanical performances of hydrogels made a great challenge for their further applications. [10][11][12] With the exploration of advanced engineering methods and novel materials, as well as structural composition precision design and fillers, an increasing number of functional hydrogels with tunable properties have been prepared, which exhibited the desired mechanical, adhesive, and conductive properties for practical applications. [13][14][15][16][17] Among the functional hydrogels, adhesive hydrogels have attracted much attention for wound healing, soft tissue reconstruction, antibiosis, and wearable electronic devices. [18][19][20][21][22] The polymeric network of hydrogel connects to the substrate materials through covalent bonds, noncovalent complexes, polymer chains, and nanoparticles. A unifying principle has been demonstrated that strong hydrogel adhesion is achieved through the synergy of chemistry, topology, and mechanics. [23] Many strategies were developed to achieve strong adhesion, including the introduction of nanoparticles. [24,25] The nanoparticles can attach to polymer chains by physical or chemical interactions to form a network in nanocomposite hydrogels, which contribute to offering energy dissipation, lowering adhesion energy, and improving the mechanical property. [26] Besides that, some special functional groups on the nanoparticles are beneficial for hydrogel adhesion. [27] In contrast, the incorporation of nanofillers could improve the conductive, [28][29][30] self-healing, stimuli-responsive properties of hydrogels. [31,32] Many nanomaterials were used in nanocomposite adhesive hydrogels such as graphene oxide, [22] silica nanoparticles, [33] iron oxide, [34] and modified carbon nanotubes. [35] In recent years, MXenes-based nanocomposite adhesive hydrogels have attracted more attention. [36] MXenes are emerging 2D transition metal carbides and/or nitrides with a general formula of M nþ1 X n T x . [37][38][39] Ti 3 C 2 T x is the first reported kind of MXenes, which was fabricated by Naguib in 2011. [40] Recently, MXenes have been widely explored due to their remarkable hydrophilic, strong mechanical, and highly conductive properties, [41,42] as well as their high specific surface area and abundant surface-terminating functional groups. [43,44] The unique combination of properties makes MXenes as attractive candidates as nanofillers for nanocomposite
