The present invention is a low-friction sliding, mechanical strength and environmental resistance to the excellent double-network gel - to provide a solid hybrid structure. The A solid having a reactive substituent radical active species on the surface, and characterized in that two or more polymer...
Compared with common hydrogels, DN gels possess higher mechanical properties. However, there are some problems with regard to their application. The largest problem is that it is difficult to synthesize DN gels in free shape because of the poor mechanical strength of the first network ...
These DN gels are prepared directly by using a squid mantle as an anisotropic soft bioproduct for the primary network and polyacrylamide (PAAm) as a synthetic polymer for the secondary network. The obtained squid/PAAm DN gel maintains the complex orientation of the muscle fibers of the squid ...
(1) one polymer first forms a single gel network and then is immersed in another polymer solution with a cross-linking agent, and secondary polymerization occurs in the first network by setting the reaction conditions; (2) the two polymers are combined to generate a hydrogel, and the gel is...
The high roughness of the gel is attributed to the different swelling degrees of different microdomains. A more uniform network can effectively avoid the stress concentration within the hydrogels29. Fig. 3: Structural changes of hydrogels before and after stretching. a Microstructure of unstretched ...
SUPER TOUGH GELS WITH A DOUBLE NETWORK STRUCTURE. Living tissues work with fantastic functions in soft and wet gel-like state. Thus, hydrogels have attracted much attention as excellent soft and wet materi... Nakajima,Tasuku,Kurokawa,... - 《Chinese Journal of Polymer Science》 被引量: 18发表...
This study evaluated biodegradation properties of four novel high-toughness double network (DN) hydrogels as potential materials for artificial cartilage. Concerning each DN gel material, a total of 12 specimens were prepared, and 6 of the 12 specimens were examined to determine the mechanical ...
