Alginate-graphene oxide hydrogels with enhanced ionic
Thin films [, , , ] and hydrogel beads of alginate-GO have been demonstrated elsewhere. Moreover, extrusion-based 3D printing was recently shown with a shear thinning ink based on polyacrylamide, sodium alginate, and graphene oxide, resulting in a double network hydrogel . However, to our knowledge, light-directed 3D printing of ionically
The main conclusion of this work is that graphene plays an important role in improving the biocompatibility of polyacrylamide hydrogels, allowing neuronal adhesion.
Reduced graphene oxide/polyacrylamide composite hydrogel
Oriented-graphene oxide/polyacrylamide (O-GO/PAM) composite hydrogel skeleton was firstly synthesized via in-situ free-radical polymerization of AM (0.3 g) for 2 h with 2 wt% APS in GO dispersion (10 mg mL −1). Then, the product was soaked in deionized water for 48 h with water changing every 12 h, followed by directional freezing
In addition, the formation of macroporous hydrogel with channel like structures along the vacuum direction under a reduced pressure of 5 mbar is reported. The macroporous hydrogel has a modulus of 40.70 kPa and shrink approximatively three times faster than the hydrogel polymerized under normal pressure and has a modulus of 10.99 kPa.
Novel Hydrogel Material as a - Scientific Reports
We report a novel graphene-oxide (GO) enhanced polymer hydrogel (GPH) as a promising embolic agent capable of treating cerebrovascular diseases and malignant tumors, using the trans-catheter
We have fabricated cationic polyacrylamide/graphene oxide (GO) hydrogels by free-radical polymerization of acrylamide (AM) and 2-(dimethylamino)ethylacrylatemethochloride (DAC) in the presence of GO. The mechanical properties and self-healing ability can be tuned by the GO content and the mass ratio of AM and DAC.
A cross-linked polyacrylamide electrolyte with high ionic
The development of compressible supercapacitors (SCs) that is tolerant to wide temperature range has been severely hindered due to the poor ionic conductivity and absence of extra functions in conventional polymer electrolytes. Herein, a highly conductive and compressible hydrogel polyelectrolyte has been prepared from polyacrylamide cross-linked by methacrylated graphene oxide (MGO-PAM) and the polyelectrolyte can maintain its excellent elasticity at −30 °C as well as its original shape
Smart elastomeric hydrogels based on polyacrylamide containing ferrimagnetic nanoparticles of BaFe 12 O 19 alone or a combination of BaFe 12 O 19 and graphene oxide were synthesized. An improvised sample preparation technique was evolved to design actuators, where the hydrogel samples in rolls form were inserted into cut pieces of hard plastic sleeve in order to fabricate a lab-level actuator.
Stretchable and Self-Healing Graphene Oxide–Polymer
Superior mechanical properties and self-healing are two hot topics in hydrogel science due to their tight relationship with the following potential application scopes. Most of the conventional hydrogels do not possess both features at the same time. Herein, we expand the recently proposed intertwined double-network mechanism and prepare a novel class of graphene oxide (GO)/poly(acryloyl-6
Graphene oxide (GO)/polyacrylamide (PAM) hydrogels with highly elastic and superstretchable mechanical behavior is fabricated by the synergistic effects of a Ca(2+) -induced GO crosslinking
Fabrication of tough, self - Wiley Online Library
Poly(acrylic acid) grafted graphene oxide (GO‐g‐PAA) was synthesized and incorporated into chemically crosslinked polyacrylamide (PAM) networks to obtain GO‐g‐PAA/PAM hydrogels, which were further treated with ascorbic acid solution at ambient temperature to give rGO‐g‐PAA/PAM hydrogels.
Here, a novel electrochemical platform made of a hydrogel–graphene oxide nanocomposite was employed to electrochemically determine simultaneously dopamine (DA) and ascorbic acid (AA). Unlike previous work, where the base electrode is modified, the active material (graphene oxide, GO) was dispersed in the hydrogel matrix, making an active nanocomposite where the electrochemical detection occurs.
