In this paper, a novel electrochromic material of 1,3,4-oxadiazole-extended viologen derivative with good coplanarity and electron acceptor-electron donor-electron acceptor structure, BPYO-C6H13, was synthesized, and a polyacrylamide-sodium alginate dual network hydrogel (PAM-SA) with advantages of ...
31 The Fourier transform infrared (FTIR) spectrum of the freeze-drying hydrogel indicates the successful synthesis of the polyelectrolyte double network (Figure S2). The bands located at 1,680–1,550 and 1,037 cm−1 belong to the amide group of AM and the sulfonic acid group of AMPS, ...
In addition, bone morphogenetic protein-2 (BMP-2) was loaded into the prepared dual network (DN) hydrogel to improve the bone regeneration function of the DN hydrogel. The resulting PEGDA/TCS/T-HNTs hydrogels showed favourable mechanical property, higher crosslinking density, the lower swelling ...
In this paper, DN hydrogels were fabricated from poly(ethylene glycol) diacrylate (PEGDA) and methacrylated poly(-glutamic acid) (mPGA). This DN hydrogel not only showed excellent mechanical properties but also good cytocompatibility as evidenced by the characterizations in terms of swelling ratio, ...

The double-network (DN) hydrogel concept developed by J.P. Gong and Y. Osada builds upon interpenetrating networks by combining brittle and ductile components to have significantly enhanced fracture properties. The generality of the DN effect was tested by creating biopolymer-based hydrogels of ...
Furthermore, the effects of viscoelasticity of GG/PEGDA DN hydrogel on the biological behavior of bone mesenchymal stem cells (BMSCs) were explored in vitro and in vivo. The results indicate that the spreading of BMSCs was closely related to the relaxation behavior of the hydrogels. GG/PEGDA ...
Herein, a new 3D-printable, osteoinductive, and bioenergetic-active double-network (DN) hydrogel containing sodium alginate (SA), poly (ethylene glycol) diacrylate (PEGDA), and sodium polyphosphate (PolyP) was developed via a two-step method. The synergy of the covalent cross-linking network ...
The present study examines the formulation of a biocompatible hydrogel bioink for 3D bioprinting, integrating poly(ethylene glycol) diacrylate (PEGDA) and sodium alginate (SA) using a double-network approach. These materials were chosen for their synergistic qualities, with PEGDA contributing to ...
The PEDOT-PVA/PEGDA double-network hydrogel shows both excellent mechanical and electrochemical performance, having a strain up to 498%, electrical conductivity as high as 5 S m-1 and specific capacitance of 84.1 +/- 3.6 mF cm(-)2. After assembling two PEDOT-PVA/PEGDA double-network ...
