Strengthening Alginate/Polyacrylamide Hydrogels Using

We successfully synthesized a family of alginate/polyacrylamide hydrogels using various multivalent cations. These hydrogels exhibit exceptional mechanical properties. In particular, we discovered that the hydrogels cross-linked by trivalent cations are much stronger than those cross-linked by divalent cations.

Mechanical strengthened alginate/polyacrylamide hydrogel

Alginate/polyacrylamide hybrid hydrogel has attracted intense interests in different fields, but the low tensile strength and stiffness limit its comprehensive application. In this hydrogel system, the alginate–cation network plays an important role. Thus, based on the unique structure of alginate and its special interaction with different metal cations, we designed a new method of introducing barium and ferric ions together to crosslink the alginate sufficiently, creating a stronger

Double network hydrogel of sodium alginate/polyacrylamide

In the past decade, a huge number of hybrid hydrogels with different structural compositions was reported . Among them, calcium-alginate/polyacrylamide (Alg/PAAm) hydrogel has been widely used in recent years with high toughness and excellent biocompatibility [, , ]. In contrary, a moderate tensile strength (156 kPa) and low stiffness (23 kPa) of Alg/PAAm could be considered as important disadvantageous which may limit its further practical applications.
