Here, we provide an effective method to fabricate magnetic ZnO clay

   nanocomposite hydrogel via the photopolymerization. The inorganic

   components endow the hydrogel with high mechanical strength, while the

   organic copolymers exhibit good adsorption capacity and separation

   selectivity to La (III) ions. An optimized hydrogel has the maximum

   compressive stress of 316.60 +/- 15.83 kPa, which still exhibits 138.98

   +/- 7.32 kPa compressive strength after swelling. The maximum adsorption

   capacity of La ion is 58.8 mg/g. The adsorption matches the

   pseudo-second-order kinetics model. La (III) ions can be effectively

   separated from the mixtures of La/Ni, La/Co, La/Cu, and La/Nd in a broad

   pH range (2.0 to 8.0). After six adsorption-desorption cycles, the

   hydrogel can maintain its adsorption capacity. This work not only

   provides a new approach to the synthesis of tough hydrogels under

   irradiation, but also opens up enormous opportunities to make full use

   of magnetic nanocomposite hydrogels in environmental fields.

Ionogel electrolytes can be fabricated for electrochemical actuators

   with many desirable advantages, including direct low-voltage control in

   air, high electrochemical and thermal stability, and complete silence

   during actuation. However, the demands for active actuators with above

   features and load-driving ability remain a challenge; much work is

   necessary to enhance the mechanical strength of electrolyte materials.

   Herein, we describe a cross-linked supramolecular approach to prepare

   tough nanocomposite gel electrolytes from HEMA, BMIMBF4, and TiO2 via

   self-initiated UV polymerization. The tough and stable ionogels are

   emerging to fabricate electric double-layer capacitor-like soft

   actuators, which can be driven by electrically induced ion migration.

   The ionogel-based actuator shows a displacement response of 5.6 mm to

   the driving voltage of 3.5 V. After adding the additional mass weight of

   the same as the actuator, it still shows a large displacement response

   of 3.9 mm. Furthermore, the actuator can not only work in harsh

   temperature environments (100 degrees C and 210 degrees C) but also

   realize the goal of grabbing an object by adjusting the applied voltage.

Herein, we describe a supramolecular approach to synthesize tough

   ionogels through self-initiated ultraviolet polymerization. The prepared

   ionogel can be used as the integrated electrolyte and separator in the

   all-solid supercapacitor. The electrochemical performance can be tuned

   by the temperature, and a higher value can be achieved at higher

   temperature.

Developing the application of high-strength hydrogels has gained much

   attention in the fields of medical, pharmacy, and pollutant removal due

   to their versatility and stimulus-responsive properties. In this

   presentation, a high-strength freestanding elastic hydrogel membrane was

   constructed by clay nanosheets, N, N-dimethylacrylamide and

   2-acrylamide-2-methylpropanesulfonic acid for adsorption of methylene

   blue and heavy metal ions. The maximum values of elongation and Young's

   modulus for 0.5% AMPSNa hydrogel were 1901% and 949.4 kPa, respectively,

   much higher than those of traditional hydrogels. The adsorptions were

   confirmed to follow pseudo-second kinetic equation and Langmuir isotherm

   model fits the data well. The maximum adsorption capacity of hydrogel

   towards methylene blue was 434.8 mg g(-1). The hydrogel also exhibited

   higher separation selectivity to Pb2+ than Cu2+. The methylene blue

   adsorbed onto the hydrogel membrane can be photocatalytically degraded

   by Fenton agent and the hydrogel membrane could be recycled at least

   five times without obvious loss in mechanical properties. In conclusion,

   this presentation demonstrates a convenient strategy to prepare tough

   and elastic clay nanocomposite hydrogel, which can not only be applied

   as recyclable membrane for the photocatalytic degradation of organic

   dye, but also for the recovery of valuables.

We report a facile solution polymerized approach to prepare

   nanocomposite hydrogels. The electrostatic assembly of positive TiO2

   nanoparticles with negative clay nanosheets obtained TiO2 clay composite

   particles, which was disassembled by the solution polymerization of

   N,N-dimethylacrylamide and homogeneously interacted with

   poly(N,N-dimethylacrylamide) chain to form nanocomposite hydrogels. The

   final nanocomposite hydrogels are mechanical, tough and transparent,

   which has the maximum 598.21 KPa compressive strength. The immobilized

   TiO2 not only acted as the photo-initiator for radical polymerization

   but also endowed the nanocomposite gel films good UV protective

   performance. This strategy can be very useful for preparing

   nanocomposite hydrogels with different functions.

A new strategy for creating enzyme-responsive hydrogels by employing an

   N-hydroxyimide-heparin conjugate, designed to act as both an

   enzyme-mediated radical initiator and an enzyme-sensitive therapeutic

   carrier, is described. A novel enzyme-mediated redox initiation system

   involving glucose oxidase (GOx), an N-hydroxyimide-heparin conjugate and

   glucose is reported. The GOx-mediated radical polymerization reaction

   allows quick formation of hydrogels under mild conditions, with

   excellent flexibility in the modulation of the physical and chemical

   characteristics. The heparin-specific enzymatic cleavage reaction

   enables the delivery of cargo from the hydrogel in amounts that are

   controlled by the environmental levels of heparanase, which is

   frequently associated with tumor angiogenesis and metastasis. The formed

   hydrogels can realize cell-specific drug delivery by targeting cancer

   cells that are characterized by heparanase overexpression, whilst

   showing little toxicity towards normal cells.
