Abstract

The invention relates to a super-hydrophobic washable conductive fabric and a preparation method thereof. The conductive fabric comprises a substrate fabric and a conductive polymer layer coated on the surface of the substrate fabric; the conductive polymer layer is polyaniline, polypyrrole, poly(3,4-ethylenedioxythiophene), polythiophene or their derivative polymer; and the substrate fabric is a blend fabric with the surface having cracks and the cross section having a cross shape, wherein the blend fabric is obtained by blending a heterotypic polyester synthetic fiber and a cotton fiber. The preparation method comprises the following steps: processing the substrate fabric with plasma, compositing the conductive polymer with the substrate fabric through utilizing an in situ polymerization method, and adjusting the molar ratio of a fluorine-containing doping agent and a polyaniline monomer and other reaction conditions to obtain conductive fabrics with different conductivities. The prepared conductive fabric which has the characteristics of high conductivity, rapid pH responsiveness, reversible super-hydrophobic performance, excellent washability and the like can be widely applied to development of wettability switching of acidity control, automatically cleaning fabrics, acidity detection and the like, so there are enormous business opportunities.

Description

technical field [0001] The present invention relates to a functional fabric and a preparation method; in particular to a superhydrophobic washable conductive fabric and a preparation method, that is, the base fabric is a special-shaped polyester-cotton blended fabric with cracks on the surface, which is treated by plasma surface modification. A conductive fabric based on conductive polymers with superhydrophobicity, fast pH responsiveness, and washability was prepared by in-situ polymerization. Background technique [0002] Wettability is one of the important characteristics of solid surfaces and is characterized by the contact angle (CA) of the surface with water. Generally, CA less than 90° is defined as hydrophilic, while CA greater than 90° and 150° are defined as hydrophobic and superhydrophobic, respectively. Generally, the surface with reversible wettability transition is usually called wettability switching (WettabilitySwitching), because of its important applicatio...
