| Abstract |
Fluorinated polymers are important functional materials for a broad range of applications, but the recycling of current fluorinated polymers is challenging. We present the first example of semi-fluorinated polymers that can undergo chemical recycling to form the corresponding monomers under ambient conditions. Prepared through ring-opening metathesis polymerization of functionalized trans-cyclobutane fused cyclooctene (tCBCO) monomers, these polymers show tunable glass transition temperatures (-2 degrees C to 88 degrees C), excellent thermal stability (decomposition onset temperatures >280 degrees C) and hydrophobicity (water contact angles >90 degrees). The hydrophobicity of the semi-fluorinated polymers was further utilized in an amphiphilic diblock copolymer, which forms self-assembled micelles with a size of similar to 88 nm in an aqueous solution. Finally, through an efficient, regioselective para-fluoro-thiol substitution reaction, post-polymerization functionalization of a polymer with a pentafluorophenyl imide substituent was achieved. The ease of preparation, functionalization, and recycling, along with the diverse thermomechanical properties and demonstrated hydrophobicity make the tCBCO-based depolymerizable semi-fluorinated polymers promising candidates for sustainable functional materials that can offer a solution to a circular economy. |
