Composites were prepared via mixing and freeze drying method that has proved in previous studies an improved mechanical properties. Freeze drying produced foams with mechanical integrity. Foams were further peocessed via hot pressing, which produced rigid films. Resulting materials have potential use in biomedical applications, which needs to be further studied 2023-03-15 Tutored research work https://hdl.handle.net/2117/386577 ETSEIB-240.176746 eng http://creativecommons.org/licenses/by-nc-nd/3.0/es/ Open Access application/pdf Universitat Politècnica de Catalunya
