"Additionally, according to the loading–unloading tests, DN-Cam exhibited a satisfactory self-strengthening behaviour."

"These PAMPS networks, incorporating different crosslinkers, serve as the first network in the DN hydrogel, with the second network identically consisting of polyacrylamide (PAAm) crosslinked with N , N ′-methylenebis(acrylamide) (MBA) ( xref ). xref The resultant DN gels are denoted as DN-Cy, DN-Pin, and DN-Cam, respectively."

"After 3 min, DN-Cam turned white in the necked region and became stronger during a second cycle of loading–unloading tests, while DN-Cy and DN-Pin did not."

sparser
"This strongly suggests that a high concentration of long-lived mechanoradicals was generated in DN-Cam, facilitating the formation of a new PNIPAm network that strengthened the material."

"As shown in xref and S7, xref when the gels, loaded with ferrous ions and xylenol orange (XO), were stretched to a strain of 6 and then unloaded in air, DN-Cam exhibited a noticeable colour change in the necked region, while DN-Cy and DN-Pin showed much weaker changes (see the ESI xref for a video clip)."

"Quantitative UV spectroscopic analysis revealed that DN-Cam generated approximately 130 μM mechanoradicals, over four times the amount produced by DN gels crosslinked with pinanediol and cis -cyclohexanediol, each of which generated only approximately 30 μM. Moreover, we investigated whether these mechanoradicals could trigger the polymerisation of monomers and crosslinkers, thereby endowing the gel with mechanoresponsive self-strengthening properties ( xref )."

"Quantitative experimental investigations showed that, compared to DN-Cy and DN-Pin, DN-Cam generates more than four times the number of mechanoradicals."
