Paper Abstract

In this research the influence of laser micromachining on physicochemical properties of bioabsorbable polymer was investigated. Poly(l-lactide) (PLLA), commonly used for manufacturing non-permanent biomedical devices, was irradiated with varying fluences by CO2 laser and by KrF excimer laser. To evaluate modification of the material, several analytical techniques were used: ATR (attenuated total reflection), XPS (X-ray photoelectron spectroscopy) and DSC (differential scanning calorimetry). We found that the laser-affected material has lower glass transition (Tg) and melting (Tm) temperatures. CO2 and KrF excimer lasers can be successfully used for cutting and drilling of polylactide.
