In a breakthrough development, a series of norbornene-based amphiphilic copolymers (PNPFE-PEG-x) have been engineered for superior fouling resistance and mechanical performance. These copolymers, synthesized via living ring-opening metathesis polymerization (ROMP), combine norbornene-based fluorinated monomers (NPFE) with poly(ethylene glycol) (NPEG) monomers, allowing for precise control over properties like water absorption, surface wettability, and mechanical strength by adjusting the NPEG content. Impressive mechanical and anti-fouling properties of PNPFE-PEG copolymersThe resulting films exhibit impressive mechanical properties, such as a tensile strength of 14.36 MPa and a breaking elongation of 376% for dry PNPFE-PEG-10% films. Additionally, these copolymers possess anti-icing properties, providing functional versatility across diverse applications, including marine anti-fouling and biomedical instruments. This development represents a significant advancement in the creation of durable, anti-fouling surfaces with excellent mechanical properties.
