Study of the biodegradation of polyhydroxybutyrate, polylactide, and their blend under the influence of microorganisms using Х-ray diffraction analysis.

The changes in the crystal structure of polyhydroxybutyrate, polylactide, and their blends during biodegradation under the influence of bacteria and fungi were studied using X-ray diffraction analysis. It was found that microorganisms induce structural transformations in polymers, which occur without significant mass loss of the samples. X-ray diffraction analysis revealed that biodegradation is a complex multifactorial process that depends on the nature of the polymer and microorganisms and is characterized by microstructural changes in the film samples.
