Abstract:

In order to endue fabrics with both hydrophobic and conductive properties, washing durable superhydrophobic electrically conductive polyethylene terephthalate (PET) fabrics were prepared by performing conductive finishing on the fabrics with self-prepared carbon black (CCB) hybrid homogenous polyestersizing agent, then constructing a micro/nano rough structure on the surface of the conductive fabrics by solvent induced crystallization (SINC) , and finally modifying with methyltrichlorosilane (MTS). The influence of the PET and CCB contents and the SINC treatment conditions on the conductive and hydrophobic properties of the fabrics were investigated, and the conductivity, wettability and washing durability and the surface microscopic morphology and crystallization characteristics of the modified fabric were characterized by field emission scanning electron microscope, differential scanning calorimeter, X-ray diffraction instrument and contact angle measurement instrument. The results indicate that the prepared superhydrophobic conductive PET fabrics have the surface resistivity of 102~103 Ω orders of magnitude and the water contact angle(WCA) greater than 150°. After ultrasonic washing for 12 h, the order of magnitude in the surface resistivity of fabrics have no change and the WCA is no less than 140°.
