Multifunctional phase-change hybrid materials containing paraffin waxes (PWs) within a microporous conjugated polymer (CP) film were developed for new sensor and actuator applications. The hybrid films were prepared simply by depositing various PWs onto CP films to show critical changes in FL intensity and color during the phase change of PWs. This fascinating FL response behavior to external heat facilitated various applications such as reversible writing/erasing, fingerprinting and thermometer sensors. An appropriate layer-supported hybrid film showed extremely fast and highly reproducible thermomechanical actuation.
