Abstract:The macromolecular architecture of strands and cross-links in a polymer network plays an indispensable role in determining its properties, such as elasticity, network dynamics, and degree of defect tolerance. However, the fixed topology of traditional networks limits their performance to a single configuration. Herein, a novel topology-switching polymer network that incorporates single-chain nanoparticles (SCNPs) as cross-links (PSNN) is proposed. Experimental and theoretical studies via microrheology and smal… Show more
