Loading and Releasing of Rhodamine B from a Composite Material Based on Nanofiber Polylactic Acid and Calcium Carbonate Microparticles Doped with Magnetite Nanoparticles

The processes of loading and release of rhodamine B from polycaprolactone nanofibers and a composite material based on mineralized polycaprolactone nanofibers, both modified and unmodified with magnetite nanoparticles, were investigated. It was established that the amount of rhodamine B loaded into polycaprolactone nanofibers mineralized with calcium carbonate microparticles exceeds the amount of dye incorporated into “pure” polycaprolactone fibers by 1.5 times.
