AB Foamed polycaprolactone impregnated with quercetin was carried out with a batchfoaming technique using supercritical CO2. The experimental design was developed to study theinfluence of pressure (15–30 MPa), temperature (308–333 K), and depressurization rate (0.1–20) onthe foam structure, melting temperature, and release tests of composites. The characterization of theexperiments was carried out using scanning electron microscopy, X-ray di ractometer, and di erentialscanning calorimetry techniques. It was observed that the porosity created in the polymer had aheterogeneous structure, as well as the impregnation of the quercetin during the process. On theother hand, controlled release tests showed a significant delay in the release of quercetin compared tocommercial quercetin.
