High water content is hard to be achieved in conductive hydrogels because a mass of conductive constituent is needed to form an internal conductive pathway. Here, we developed anisotropic electrically conductive hydrogels with high water content based on bacterial cellulose (BC). Polystyrene sulfonate (PSS) was grafted to the acryloyl chloride-modified BC to provide a template for the subsequent synthesis of poly(3,4-ethylenedioxythiophene) (PEDOT). The BC-<i>g</i>-PSS/PEDOT hydrogels obtained w
The adhesion of stimuli-responsive hydrogels was achieved via electrophoresis. The adhered gels were quite stable in water during repetitive swelling and shrinking processes, respectively.
Hydrogel constructs were rapidly fabricated via the electrophoretic adhesion of oppositely charged microbeads. The reversible preparation of hydrogel constructs was achieved by the reconstruction of microbead networks.
Two biodegradable hydrogels were stitched together through the intermediary of oppositely charged polyelectrolytesviaelectrophoresis. The two gels in contact adhered when an electric field was applied with a cationic gel on the anode and an anionic gel on the cathode. Adhesion of the two gels was not observed when the opposite electric field was applied or with pressure bonding. Adhesion of cationic and anionic hydrogels should exhibit repeatability characteristics. Electrophoretic adhesion of t
A sol–gel transition and the self‐healing of the resultant hydrogels are achieved utilizing a metallo‐supramolecule composed of terpyridine‐terminated low‐molecular‐weight three‐armed poly(ethylene glycol) (trisPEGtpy 450 ) in water at ambient temperature. The gelation of trisPEGtpy 450 with cobalt ions occurs by aerobic oxidation (mild conditions), and therefore the solution can be moulded into any shape hydrogel. The solation of the cured hydrogels occurs spontaneously upon the addition of the
A reusable bifunctional biomimetic material with a coral-like structure was prepared and applied in the analysis of phosphorylated and glycosylated proteomics.
