... storage modulus of silk fibroin/collagen hydrogels was significantly higher than the loss modulus, suggesting that collagen and silk fibroin were physically crosslinked and then formed interpenetrating networks (IPNs). Therefore, the hybrid hydrogels behaved more like elastic solid than viscous liquid [ 96 , 97 ]. The mechanism is illustrated in Fig. 3 [95] . The findings demonstrate that the silk fibroin/collagen blends possess tunable mechanical and biological properties compared to pure collagen and pure silk fibroin, which are the candidates for cell delivery and tissue ...

To advance ecological civilization, developing sustainable, eco-friendly high-strength and ultra-tough alternatives to non-sustainable synthetic fibers, such as nylon, is crucial. This necessitates a deeply scientific understanding of the fundamental determinants of fiber strength and toughness, as well as overcoming engineering challenges for cost...
