  • Fiber comprising thermoplastic elastomer and silica nanoparticle, stretchable hydrophobic fiber article prepared therewith, and method for preparing the same
    Patent number: 11713543
    Abstract: The present disclosure relates to a fiber for manufacturing a stretchable hydrophobic fiber article, the fiber including silica nanoparticles which are surface-modified such that the silica nanoparticles include a hydrocarbon chain, and a styrene-based thermoplastic elastomer, a stretchable hydrophobic fiber article manufactured therefrom, and a manufacturing method thereof. A fiber and a fiber article according to the present disclosure may have high hydrophobicity, preferably both superhydrophobicity and elasticity. Further, as the fiber and fiber article have excellent mechanical stability and chemical durability, the fiber and fiber article may stably exhibit the aforementioned high hydrophobicity and elasticity even under the harsh conditions.
    Type: Grant
