Single-material solvent-sensitive actuator from poly(ionic liquid) inverse opals based on gradient dewetting†
Abstract
A novel and reversible single-material solvent-sensitive actuator was developed from poly(ionic liquid) inverse opals based on a gradient wetting/dewetting process combining the strong hydrogen bonding interaction between the solvent and polymer. This study will provide an important insight for the design and fabrication of novel-type solvent-actuator materials.
