AB  - Structure design provides an effective solution to develop advanced soft 
      materials with desirable mechanical properties. However, creating multiscale 
      structures in ionogels to obtain strong mechanical properties is challenging. 
      Here, an in situ integration strategy for producing a multiscale-structured 
      ionogel (M-gel) via ionothermal-stimulated silk fiber splitting and moderate 
      molecularization in the cellulose-ions matrix is reported. The produced M-gel 
      shows a multiscale structural superiority comprised of microfibers, nanofibrils, 
      and supramolecular networks. When this strategy is used to construct a 
      hexactinellid inspired M-gel, the resultant biomimetic M-gel shows excellent 
      mechanical properties including elastic modulus of 31.5 MPa, fracture strength of 
      6.52 MPa, toughness reaching 1540 kJ m(-3) , and instantaneous impact resistance 
      of 3.07 kJ m(-1) , which are comparable to those of most previously reported 
      polymeric gels and even hardwood. This strategy is generalizable to other 
      biopolymers, offering a promising in situ design method for biological ionogels 
      that can be expanded to more demanding load-bearing materials requiring greater 
      impact resistance.
