| Popis: | In the present work, the methodology of the production of porous chitosan scaffolds with the participation of hydroxyapatite (HAp) by the electrolytic method has been presented. The electrolysis of 1% solution of chitosan in 1% acetic acid (containing HAp) has been conducted. In the process of electrolysis, chitosan acetate underwent reduction ( to NH2) and deposited on the cathode in the form of porous chitosan hydrogel containing different quantities of HAp. In order to improve antibacterial qualities, the scaffolds were covered with a 15 μm layer of nanosilver. The obtained chitosan structures were further subjected to lyophilisation. The aim of the research is to examine the influence of the conditions of the process on the rate of the scaffolds production as well as the morphology of the structures. Images (SEM) were taken in order to examine the surface structure of scaffolds, dispersion of HAp in the polymer matrix as well as the size of the nanosilver layer on the chitosan surface. |
