Properties of aluminum deposited chemically recycled PET fabrics

To investigate the aluminum deposition on the chemically recycled polyethylene terephthalate (CR-PET) fabrics by DC magnetron sputtering, effects of sputtering parameters (sputtering power and deposit time) on the properties of the Al deposited CR-PET fabric were examined. The variations in the properties such as wettability, optical and thermal insulation property of the CR-PET fabric sputtered under various sputtering parameters were discussed. Wettability of the Al deposited CR-PET fabrics decreased with an increase of sputtering power and deposit time, and then they leveled off above a certain condition. The light reflectance of the Al deposited CR-PET fabrics showed a maximum point with proper sputtering power and deposition time. The thermal insulation property of the Al deposited CR-PET fabrics improved with sputtering power and deposit time.
