Hydrophobisation of hydrophilic imitation leather with polyester surface by atmospheric pressure plasma treatment

This paper investigates the parameters of atmospheric pressure plasma (APP) jet for enhancing the hydrophobicity of polyester surface in imitation leather with a precursor of tetramethylsilane. A wide range of process parameters were studied. Under a specific combination of process parameters, a hydrophobic surface was obtained on the APP-treated sample with good hydrophobicity to water, coffee as well as milk tea.
