Article Description

The aim of the study is to determine the effect of long-term exposure to Ringer's solution on the physical properties of biodegradable polymer coatings on the titanium 6-aluminum 7-niobium alloy substrate. 30 day, 60 day and 90 day research periods are applied. The work is performed on a titanium 6-aluminum 7-niobium alloy modified by sandblasting and anodic oxidation. Three biodegradable polymer coatings: poly(glycolide-ϵ-caprolactone); poly(glycolide-ϵ-caprolactone-L,L-lactide) and poly(D,L-lactide-glycolide), containing ciprofloxacin are used in the study. The coatings are deposited by dip-coating method. Topography, wettability, and adhesion of the coatings are analyzed. The analysis of the test results indicates that regardless of the type of coating and the number of dips, the obtained coatings are continuous, hydrophilic, map the topography of the substrate, and slight change roughness after exposure to Ringer's solution. After three months of exposure to Ringer's solution, an increase in wettability and, at the same time, a significant decrease in adhesion is observed. The poly(D,L-lactide-glycolide) coatings are characterized by the greatest adhesion to the substrate.
