  • Publication number: 20260179956
    Abstract: Embodiments described herein relate to binders including one or more portions, and electrochemical cells including the same. Specifically, in some embodiments, binders may include a first portion, a second portion, and, optionally, a functional portion coupled to at least one of the first portion or the second portion. In some embodiments, the functional portion may also be coupled to first portion. In some embodiments, the second portion is coupled to the first portion in a linear structure, or grafted as a side chain at a predetermined location along a length of the first portion. In some embodiments, the first portion has a first glass transition temperature, and the second portion has a second glass transition temperature. The second glass transition temperature may be greater than the first glass transition temperature.

  • Publication number: 20230159435
    Abstract: Formamide group-containing monomers and polymers made by polymerizing the monomers are provided. Also provided are methods of polymerizing the monomers and methods of synthesizing functionalized polymers by pre- and/or post-polymerization functionalization. The monomers are non-toxic and can generate highly reactive isocyanate and isonitrile precursors in a one-pot synthesis that enables the incorporation of complex functionalities into the side-chain of the polymers that are synthesized from the monomers.
