Embodiment 1
(1) Preparation of impact-resistant wearable material (CFS-1 / ENG): 1.0 g of sodium alginate was added to 100 mL of deionized water, stirred at 30 °C for 0.5 h, and then 3.0 g of discarded collagen fibers were added to The above sodium alginate aqueous solution was continuously stirred for 2.0 h, and finally the prepared mixed system was poured into a mold with a size of 10.5 × 10.5 × 2.0 cm and freeze-dried to obtain a collagen fiber sponge (CFS-1). 150 mL of hydroxysilicone oil was continuously stirred at 120 °C, then 11.5 g of boric acid was added, and the reaction was condensed and refluxed for 3.0 h to obtain an elastic non-Newtonian gel (ENG).
[0019] 100 g ENG and 4.0 g benzoyl peroxide were added to 150 mL acetone for sonication for 30 min. CFS-1 was then immersed in acetone containing ENG and benzoyl peroxide for 30 min and dried. By repeating the above impregnation and drying process, CFS-1 / ENG was finally obtained by vulcanizing the composite at 50 °C for 4.0 h.

Embodiment 2
(1) Preparation of impact-resistant wearable material (CFS-2 / ENG): 1.0 g of sodium alginate was added to 100 mL of deionized water, stirred at 30 °C for 0.5 h, and then 4.0 g of waste collagen fibers were added to The above sodium alginate aqueous solution was continuously stirred for 2.0 h, and finally the prepared mixed system was poured into a mold with a size of 10.5 × 10.5 × 2.0 cm and freeze-dried to obtain a collagen fiber sponge (CFS-2). 150 mL of hydroxysilicone oil was continuously stirred at 120 °C, then 11.5 g of boric acid was added, and the reaction was condensed and refluxed for 3.0 h to obtain an elastic non-Newtonian gel (ENG).
[0022] 100 g ENG and 4.0 g benzoyl peroxide were added to 150 mL acetone for sonication for 30 min. CFS-2 was then immersed in acetone containing ENG and benzoyl peroxide for 30 min and dried. By repeating the above impregnation and drying process, CFS-2 / ENG was finally obtained by vulcanizing the composite at 50 °C for 4.0 h.

Embodiment 3
(1) Preparation of impact-resistant wearable material (CFS-3 / ENG): 1.0 g of sodium alginate was added to 100 mL of deionized water, stirred at 30 °C for 0.5 h, and then 5.0 g of discarded collagen fibers were added to The above sodium alginate aqueous solution was continuously stirred for 2.0 h, and finally the prepared mixed system was poured into a mold with a size of 10.5 × 10.5 × 2.0 cm and freeze-dried to obtain a collagen fiber sponge (CFS-3). 150 mL of hydroxysilicone oil was continuously stirred at 120 °C, then 11.5 g of boric acid was added, and the reaction was condensed and refluxed for 3.0 h to obtain an elastic non-Newtonian gel (ENG).
[0025] 100 g ENG and 4.0 g benzoyl peroxide were added to 150 mL acetone for sonication for 30 min. CFS-3 was then dipped in acetone containing ENG and benzoyl peroxide for 30 min and dried. By repeating the above impregnation and drying process, CFS-3 / ENG was finally obtained by vulcanizing the composite at 50 °C for 4.0 h.
