The effect of a thermostable cutinase on the surface properties of PET films was investigated. PET films were incubated with cutinase at different temperatures (45-85°C) and then characterized by FTIR-ATR. Upon cutinase treatment the surface of PET attained a higher crystalline character, as denoted by the trend of the A1341/A1410, A1370/A1410, and I1120/I1100 spectroscopic indexes, the effect being stronger at above Tg (72°C). The use of FITC-labeled cutinase showed that a remarkable amount of enzyme remained attached onto the PET surface when the treatment temperature exceeded the Tg value.

Abstract:	The effect of a thermostable cutinase on the surface properties of PET films was investigated. PET films were incubated with cutinase at different temperatures (45-85°C) and then characterized by FTIR-ATR. Upon cutinase treatment the surface of PET attained a higher crystalline character, as denoted by the trend of the A1341/A1410, A1370/A1410, and I1120/I1100 spectroscopic indexes, the effect being stronger at above Tg (72°C). The use of FITC-labeled cutinase showed that a remarkable amount of enzyme remained attached onto the PET surface when the treatment temperature exceeded the Tg value.
