Abstract

Monolayers of biodegradable polymers, poly(caprolactone) (PCL), poly(caprolactone) diol (PCL-diol), and poly(caprolactone) triol (PCL-triol) in the air/water interface were studied and characterized. The Langmuir-Blodgett technique was used for the monolayer transfer onto hydrophilic and Hydrophobie solid substrates. The results obtained in both cases are dependent on the functional groups incorporated in the respective polymers. The surface energy (SE), and the polar and dispersion contributions, ?p and ?d, respectively, were obtained by wettability measurements. For polymeric spin-casted thin films deposited over glass, the results also indicate an increment in the polymer hydrophilicity by hydroxyl groups insertion.
