Abstract

In this study, milife fabrics (polyester nonwoven fabrics) were used. Three common silanes including octyltriethoxysilane, phenyltriethoxysilane and tetraethoxysilane have been prepared by sol-gel technique to treat the milife fabrics with and without copper coating. The main aim of the study is to protect the conductive copper layer of the milife fabric by the silanization proces. Surface morphology have been measured by scanning electron microscope to prove the deposition of silane, surface roughness was measured by confocal microscope and electromagnetic shielding effectiveness (EMI) have been tested to prove the change in EMI values with respect to silane coating. From the results, it was obvious that EMI of the copper coated milife treated with phenyltriethoxy silane ranging from 40 to 50 dB increases about 80% of the values of copper coated milife compared to other two silane coatings. In addition, SEM showed that deposition of silane on the fabric surface depending on the different types of silane used for the sol-gel coating.
