Abstract
The influence of fillers on the structures of siloxane films was studied. Three variants of fillers are considered: ethyl alcohol, chitosan and sodium bicarbonate with its subsequent removal. It is shown that the use of alcohol leads to a change in the surface structure and the formation of numerous pores-“pits”. The use of sodium bicarbonate or chitazan makes it possible to create developed networks of pores intersecting with each other and having access to the surface. The possibility of controlling the thickness of porous layers by changing the concentration of the introduced filler is shown. It is concluded that the studied variants of the modification of the structure of siloxane films open up wide opportunities for creating drug delivery systems or other active agents, including controlled prolonged action.
