Smart gel
From Wikipedia, the free encyclopedia
Smart gel is a type of smart material.
Smart gel is a functional material that actively changes its volume and properties (hydrophilicity/hydrophobicity) in response to changes in external environments such as temperature, pH, light, and electric fields. They have been suggested for applications such as temperature-responsive recovery of moisture from the air as water, drug delivery systems, and medical biocompatible patches.[1][2][3]
