The study of the structure and optical properties of gellan-PVA, gellan-PVP and gellan-PVI composites

The present study reports the results of an investigation on the preparation, characterisation and determination of optical properties of gellan-polyvinyl alcohol (PVA), gellan-poly (N-vinyl-pyrrolidone) (PVP) and gellan-poly (N-vinyl-imidazole) (PVI) composites and it represents a part of a major work dedicated to the development of new source of dielectric biomaterials for medical devices. The choice of PVA, PVP and PVI was based on the fact that their polymers are good electroactive synthetic polymers.
