Effect of the photoinitiator amount on properties and structure of the hydrogel matrix

key words: hydrogels, photopolymerization, chitosan, photoinitiator, adsorption, degree of crosslinking.

Summary:

The paper presents a synthesis of the hydrogel materials by photopolymerization. A series of materials differing in the amount of photoinitiator was prepared. In these studies the ability of swelling of attained materials was determined. What is more, incubation studies were also carried out. Measurements of contact angles was conducted and a chemical structure of obtained materials was defined using FT-IR spectroscopy. On the basis of the research the impact on the amount of the photo-initiator on the structure of a polymeric material have been defined. Synthesized materials were characterized by a different degree of the cross-linking, and therefore they have different properties. Hence the conclusion that possibility of the structure modifying of the material creates more opportunities for its use.
