Abstract

Strong and stretchable hydrogels are in great demand but challenging due to the trade-off between the strength and stretchability. Here, we successfully prepared highly strong and stretchable sodium alginate/polyacrylamide (SA/PAM) double network (DN) hydrogels by using swollen calcium alginate fiber (CAF) as the first energy dissipating network. The swollen fibers contributed two functions: the homogeneous SA ionic crosslinked-polymer networks and the soft fiber reinforcement. In contrast to the stiff fiber, the soft CAF provide more effective energy dissipation transferring from soft fiber to the liquid hydrogel. The as-prepared hydrogels demonstrated a high tensile strength (0.83 MPa), high stretchability (4230 %), and high toughness (15.7 MJ/m³), as 5, 3 and 14 times of the SA/PAM hydrogels. This soft fiber-reinforced strategy offers a new way for preparing high-performance hydrogels, broadening their applications areas.

期刊介绍： Progress in Natural Science: Materials International provides scientists and engineers throughout the world with a central vehicle for the exchange and dissemination of basic theoretical studies and applied research of advanced materials. The emphasis is placed on original research, both analytical and experimental, which is of permanent interest to engineers and scientists, covering all aspects of new materials and technologies, such as, energy and environmental materials; advanced structural materials; advanced transportation materials, functional and electronic materials; nano-scale and amorphous materials; health and biological materials; materials modeling and simulation; materials characterization; and so on. The latest research achievements and innovative papers in basic theoretical studies and applied research of material science will be carefully selected and promptly reported. Thus, the aim of this Journal is to serve the global materials science and technology community with the latest research findings. As a service to readers, an international bibliography of recent publications in advanced materials is published bimonthly.
