Влияние [gamma]-стерилизации на поверхностные свойства пленок на основе полимолочной кислоты модифицированных низкотемпературной плазмой

Abstract

In this work the effect of [gamma]-sterilization and their combined effect with low-temperature plasma (treatment time was 30, 60, and 90 s) on the surface properties of polylactic acid (PLA) films was investigated. An analysis of the data showed that the starting films possess hydrophobic properties with a contact angle in the range of (80-:78)°, and treatment with low-temperature plasma together with [gamma]-sterilization increases hydrophilicity and decreasing the contact angle by ( 27-33%).
