Аннотация: Blends consisting of the poly-3-hydroxybutyrate-co-3-hydroxyvalerate (PHBV) copolymer and poly?-caprolactone (PCL) were used to prepare polymer ?lms by casting solution technique. The structure and physical-mechanical, and biological properties of the ?lms were examined as in?uenced by the ratios of the blend components. The microstructure of the ?lms was determined by the dominant component: the ?lms had porous surface if the percentage of PHBV was higher than that of PCL and were relatively smooth if the dominant component was PCL. The highest elongation at break (190-368 %) was exhibited by the ?lms prepared from the blends containing 5-25 % PHBV; at 25 % PHBV, local maxima of tensile strength (16 MPa) and Young's modulus (529 MPa) were observed. Biocompatibility of the ?lms prepared from the blends was studied in the culture of NIH 3T3 mouse ?broblast cells. Results of SEM and DAPI staining, determination of the number of attached cells, and MTT assay showed the absence of cytotoxic effects and high cell adhesion and proliferation, which in some cases were higher than on ?lms prepared from pure PHBV and PCL. Thus, PHBV/PCL blends are suitable materials for constructing cell scaffolds for tissue engineering and other reconstructive technologies.
