This month I prepared the paper for the conference "Advanced Materials and Technologies AMT 2013”. The concept of my dissertation and possibility to use the results of research in the medical industry were described in the extended abstract, which will be presented on the Symposium “Materials Science for the industry”. In the reporting month, I also continued analysis of the polyelectrolyte coatings structure by using the ATR – FTIR. I performed a few diffusion experiments. I’ve spent some time on visualization of polyelectrolyte films surface after Impact R tests. Moreover I prepared samples which will be subjected to microcalorimetric analysis. In the further research I would like to focus on cross-linking by genipin.
