A class of sulfonimide salts for solid-state electrolytes can be synthesized based on successive SAr reactions of fluorinated phenyl sulfonimides: Fluorinated Aryl Sulfonimide Tags (FAST). The chemical and electrochemical oxidative stability of these FAST salts as well as other properties like solubility, Lewis basicity, and conductivity can be tuned by introducing different numbers and types of nucleophilic functional groups to the FAST salt scaffold.

Sulfonimide salts for battery applications

The present invention provides polymers and methods of preparing the same. In certain embodiments, the polymers comprise acrylate repeating units that have been derivatized (e.g., reduced and/or substituted) to form new polymeric structures. In certain embodiments, the polymers described herein self-assemble to form well-defined nanostructures. In some instances, the nanostructures exhibit relatively small d-spacing (e.g., a d-spacing value of 10 nm or less). Due to their properties, the polymers described herein are useful in a variety of applications including functional materials and biomedical applications.

Polymers and uses thereof

Methods, compositions, reagents, and systems that allow for the preparation and utilization of sulfonamide salt polymer electrolytes are disclosed herein. Methods and reagents to prepare sulfonamide salt monomers are also disclosed herein. The sulfonamide salt polymer electrolytes can be used as components in energy storage devices, conductive materials, electrochemical cells, gels, adhesives, and drug delivery vehicles.

Polymerizable sulfonamide compounds and polymers thereof

Disclosed are methods, compositions, kits, and reagents to prepare compounds (e.g. polymers and small molecules) via radical reactions by utilizing thermoresponsive and photoresponsive gels. This invention discloses the preparation of polymers via controlled radical polymerizations from an iniferter or initiator, one or more reactant monomer, and a thermoresponsive and photoresponsive gel. Embodiments of the invention show that the polymerization is reversibly activated and/or deactivated by controlling one or more of the following external control stimuli: temperature, light, and catalyst presence. This invention also relates the preparation of Gel-PTH, a heterogeneous thermoresponsive and photoresponsive gel.
