Abstract
Thermally responsive materials, porous membranes comprising the thermally responsive materials, and batteries incorporating the porous membranes as thermally responsive separation membranes are provided. Also provided are methods of making the thermally responsive materials. The thermally responsive materials comprise upper critical solution temperature (UCST) polymers covalently bound to a support substrate.
