Abstract
Poly(3-hydroxybutyrate) and chitosan are among the most widely used polymers for biomedical applications due to their biocompatibility, renewability and low toxicity. The creation of composite materials based on biopolymers belonging to different classes makes it possible to overcome the disadvantages of each of the components and to obtain a material with specific properties. Solving this problem is associated with difficulties in the selection of conditions and solvents for obtaining the composite material. In our study, acetic acid was used as a common solvent for hydrophobic poly(3-hydroxybutyrate) and chitosan. Mechanical, thermal, physicochemical and surface properties of the composites and homopolymers were investigated. The composite films had less crystallinity and hydrophobicity than poly(3-hydroxybutyrate), and the addition of chitosan caused an increase in moisture absorption, a decrease in contact angle and changes in mechanical properties of the poly(3-hydroxybutyrate). The inclusion of varying amounts of chitosan controlled the properties of the composite, which will be important in the future for its specific biomedical applications.

Utilisation des équipements
L’étude a examiné des films composites de poly(3-hydroxybutyrate) et de chitosane préparés avec de l’acide acétique comme solvant commun. Les propriétés mécaniques ont été étudiées avec les propriétés thermiques, physicochimiques et de surface. Le résumé disponible ne précise ni le type d’essai mécanique, ni les grandeurs mécaniques mesurées, ni l’instrument ; le rôle du Mach-1 ne peut donc pas être vérifié.
