Nanocoatings with high moisture barrier
Advanced nanocoatings utilizing clay nanosheets provide a superior moisture barrier for PLA and PET films, achieving WVTR < 50 g/(m2*day) under tropical conditions. Ready for collaboration to tailor applications.
Overview
The University of Connecticut presents an advanced nanocoating technology that significantly enhances the moisture barrier properties of PLA and PET films. By aligning clay nanosheets at a high concentration and orientation, this solution achieves a water vapor transmission rate (WVTR) of less than 50 g/(m2*day) even in challenging tropical conditions (38 °C, 90% relative humidity). This innovation offers a robust solution for industries requiring enhanced protective coatings, such as packaging and electronics.
