Loading and release of rhodamine B from a composite material, based on polycaprolactone nanofibers and calcium carbonate microparticles, doped with magnetite nanoparticles

The investigation of rhodamine B loading and release processes from polycaprolactone nanofibers and a composite material based on mineralized polycaprolactone nanofibers, modified and not modified with magnetite nanoparticles, are presented. It was shown that the volume of rhodamine B loaded into polycaprolactone nanofibers mineralized with calcium carbonate microparticles is 1.5 times greater than the volume of the dye introduced into “pure” polycaprolactone fibers.
