“…For example, Liu et al incorporated GO into a polyacrylamide (PAM) hydrogel, and the composite hydrogel exhibited high tensile strength, high toughness and larger elongation at break. 23 Our previous study also demonstrated that the incorporation of graphene into a-CD/a star-like block copolymer AE73 weakened the strength of the hydrogel, while the insertion of GO enhanced the mechanical strength of the hydrogel, and studied the absorption of the dye preliminarily. 22 Several studies have been reported about nanocomposite supramolecular hydrogels based on polyrotaxanes of cyclodextrins and polymers, such as those incorporating polysaccharide nanocrystals, carbon nanotubes (CNTs), and graphene into the hydrogels.…”

Supramolecular hydrogels were prepared using a-cyclodextrin (a-CD) and a poloxamine (reverse Tetronic 90R4, T90R4) which has four diblock arms with a poly(propylene oxide)-poly(ethylene oxide) (PPO-PEO) structure. The a-CD can slide past the PPO blocks and towards the middle PEO blocks owing to the unsuitable energy between a-CD and PPO to form a-CD/T90R4 inclusion complexes (ICs). The incorporation of graphene oxide (GO) into a-CD/T90R4 ICs changes their phase behavior and forms mechanically strong hydrogels because of the hydrogen-bonding between the GO nanosheets and the a-CD and PEO blocks of T90R4. The native hydrogel, as well as the a-CD/T90R4/GO hybrid hydrogels, have been thoroughly characterized by using various microscopy techniques. Field emission scanning electron microscopy (FE-SEM) was used to observe the morphology of the hydrogel, and differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) were used to evaluate the thermal stability of the hydrogel. Fourier transform infrared (FT-IR) spectroscopy and X-ray diffraction (XRD) were used to characterize the interactions within the supramolecular assemblies and the degree of crystallinity of the xerogels, respectively. The experimental results demonstrated that a-CD/T90R4/GO hybrid hydrogels could adsorb various dyes selectively, and that it is a promising candidate for sewage treatment, while the native one cannot adsorb the dyes well. Moreover, the native a-CD/T90R4 hydrogel has excellent biocompatibility, and the results of the in vitro drug release study showed that the injectable doxorubicin (DOX)-loaded hydrogel is appropriate for the controlled release of anticancer drugs, while the a-CD/T90R4/GO hybrid hydrogels can reduce the release rate of DOX.

“…A valuable approach for the preparation of hybrid hydrogels composed of GO and GO derivatives is the non-covalent inclusion into supramolecular structures, like cyclodextrins. This confers high elastic behaviour at elevated temperature to the resulting supramolecular hydrogels [ 140 ]. A key example of this concept was developed by a preliminary stabilization of GO in solution by the surfactant Pluronic F-127 and a subsequent inclusion into α-cyclodextrins.…”

Recent Advances in the Synthesis and Biomedical Applications of Nanocomposite Hydrogels

Hydrogels sensitive to electric current are usually made of polyelectrolytes and undergo erosion, swelling, de-swelling or bending in the presence of an applied electric field. The electrical conductivity of many polymeric materials used for the fabrication of biomedical devices is not high enough to achieve an effective modulation of the functional properties, and thus, the incorporation of conducting materials (e.g., carbon nanotubes and nanographene oxide) was proposed as a valuable approach to overcome this limitation. By coupling the biological and chemical features of both natural and synthetic polymers with the favourable properties of carbon nanostructures (e.g., cellular uptake, electromagnetic and magnetic behaviour), it is possible to produce highly versatile and effective nanocomposite materials. In the present review, the recent advances in the synthesis and biomedical applications of electro-responsive nanocomposite hydrogels are discussed.
