The working principle of thermal responsive nanomaterials typically involves a phase transition or a molecular rearrangement that triggers a functional response. For instance, certain polymers exhibit a lower critical solution temperature (LCST) or an upper critical solution temperature (UCST). When the temperature crosses these thresholds, the materials either precipitate out of solution or dissolve, respectively. These properties can be tailored by modifying the chemical structure of the nanomaterials.
