1. A highly strong and tough photo-crosslinked hydrogel material, wherein the highly strong and tough photo-crosslinked hydrogel material is prepared from the following three components in a biocompatible medium:
Component A: o-nitrobenzyl phototrigger modified photosensitive polymer derivative;
Component B: double bond groups modified polymer derivative;
Component C: photoinitiator,
the o-nitrobenzyl phototrigger modified photosensitive polymer derivative is selected from the following component A-1 to A-30:
the double bond groups modified polymer derivative having a structure shown in Formula III:
where in the Formula III,
R1′ and R2′ are selected from hydrogen;
R3′ is selected from hydrogen or methyl;
R4′ is selected from an alkyl group, an ether group, an ester group, or an amide group;
n≥2;
P1′ is hydrophilic natural macromolecules or hydrophilic synthetic polymers;
wherein the concentration of the o-nitrobenzyl phototrigger modified photosensitive polymer derivative is 1% wt-40% wt, the concentration of the double bond groups modified polymer derivative is 0.05% wt-10% wt, the concentration of the photoinitiator is 0.1% wt-3% wt, and the rest is the biocompatible medium.
