ABSTRACTThe 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 methacrylated chondroitin sulfate (MCS) and polyacrylamide (PAAm) and extended upon creating DNs of MCS and poly(N,N dimethyl acrylamide) (PDMAAm), verifying that DNs were not limited to the original combination of poly(2-acrylamido-2-methylpropanesulfonic acid) (PAMPS)/polyacrylamide (PAAm). Further, the mechanical properties were varied by changing the monomer concentrations, cross-linker concentrations and the addition of cross-linking groups through copolymerizations of MCS and poly(ethylene glycol) diacrylate (PEGDA). Overall, this work demonstrates that a broad range of mechanical properties achievable through DN effect under tension and compression, generally independent of the swelling degree, which is fundamentally different behavior than possible with single networks.

Germination And Growth

The germination and growth of mycelium are slightly affected by the addition of less than 5%sbrlatex. The latex is distributed in the culture medium to wrap them and fill in the void so that the culture medium can be tightly bonded together, and the mycelium is bonded to the latex, forming a double network. An increased specific strength of the composite would be expected in this case. Silane coupling agent seems to have no effect on mycelial growth, but it can improve the bond between latex and culture medium so that the specific strength of the composite is improved.
