Abstract
The present invention relates to a high performance cross-linked triblock cationic functionalized polymer for electrochemical applications, and methods of making and using the same. The invention also relates to a tunable hydrogenated polymer, that can be functionalized with a particular cation for a particular application, and the method of making the hydrogenated polymer and tuning the hydrogenated polymer for the application.
Claims4
A method of hydrogenating a triblock polymer, the method comprising:
- selecting a triblock polymer comprising a structure A-B-A, wherein unit A is selected from the group consisting of a halogenated polyvinyl benzyl or a halogenated polymethyl styrene;
- and the unit B is independently selected from the group consisting of a polyisoprene, a polycyclooctene, a polycycloocadiene, and a polycyclooctatriene;
- dissolving the triblock polymer and a ρ-toluenesulfonyl hydrazide in a solvent to form a solution;
- heating the solution to hydrogenate the triblock polymer forming a hydrogenated triblock polymer;
- precipitating the hydrogenated triblock polymer from the solvent of the solution;
- cleaning the hydrogenated triblock polymer to remove a hydrazine by-product;
- dissolving the hydrogenated triblock polymer in a second solution;
- applying the second solution to a substrate;
- evaporating the second solvent to form a film on the substrate;
- converting the unit A to a cationic polymer by quaternizing with a base.
