Thermal, and wettability properties of the PBCE-based films. Thermal, X-Ray Diffraction (XRD) and Wettability properties of PBCE*, PBCE, BDG10 and BDG30 polymer films. Thermal properties were analyzed by DSC: melting temperatures (Tm) and enthalpies (ΔHm) were calculated from the first and second heating scans, while glass transition temperature (Tg) and the specific heat increment (ΔCp) were calculated from the second heating scan. Wettability was analyzed by water contact angle (WCA) measurements by using sessile drop method in air. PBCE* measurements were from References n.22 and n.23.
